Breathtaking amazing ❤
Which brand you think is the best ?
Out of the ones I've tried it's definitely APT.
It takes time for that bacteria to form
This is 8 month old matrix. It doesn't work. It literally can't work as claimed in oxygenated water like an aquarium.
Keep testing
I agree with you. It has been 2 weeks in my filter and my nitrates are still very high. Thete was no change.
This is what I want to learn .. I want to be able to go out and find these plants in specific places and just add them to my tank
Just experiment. Most will be growing in wet areas like the sides of waterways. One thing someone taught me was that most aquatic plants won't even be in the water. They'll be near the water. There's way more CO2 in the air so they grow better out of the water.
@@underwaterjungle thank you so much. .. I just got into aquariums but I work as a organics removal.. so I get rid of moss, algae, mold, etc… although they are diff .. they are similar.. point is.. all these areas I work in have so much moss it’s unreal. I’ve got a job coming up that’s filled with ferns, moss, plants growing on moss.. it’s beautiful tbh but I’ll make sure to take most of it home before I eliminate it.
@@LesDL69 There's quite a few mosses and some ferns that can grow submersed. I would totally take some plastic bags or something to collect a bunch of different samples. CO2 is going to increase your success rate too
@@underwaterjungle thank you so much
It does. My 30L aqua tank , nature style. I use totally 2L matrix. 1L in slow flow additional filter. Nitrate in my tank is zero. I just figured it when i regconised that my plants stop growing up ( with strong co2, and new substrate). I tested and i were shock by the result because I just use matrix , not denitrate. I accidently set up anaerobic barteria cycle in my tank. Now i have to keep fertilizing 3ml seachem Nitrogen everyday to keep NO3 in my tank 15 ppm to feed my plants. Wasted money 😅
It's the plants consuming the nitrogen. Matrix is a fraud.
@@underwaterjungle Actually, i have 2 tanks, similarly. Both using matrix, and have the same fertilizer doses. Thats why i know the problem come from the "matrix slow flow system". Now, i have to add 2ml / day seachem nitrogen to keep it stable. 1ml and 3ml is a big difference. You can search and try to set up slow flow filter system. It would be an interrested experience.
Have you tried the same experiment but start from day one with Excel? I would home no one would let their algae get that out of control in the aquarium before acting on it. I feel your experiment was doomed from the start and asking too much of the product.
I haven't but of all the comments, this one actually makes the most sense. My initial motivation was that people often desperately grab some Excel once things are out of control so I was trying to make something really nasty to see if it would kill it. It would definitely be interesting to see if it would even ever get to that bad a state if dosed regularly.
It takes 3 months to work. I've tested it.
this was using 8 month old media. it doesn't work under any normal scenario. you could concoct a low flow, low oxygen setup but there wouldn't be enough oxygen in the water to actually keep your fish alive.
You should have added some fertilizer
Great explainer…thanks.
Not a control experience. But I'll tell you one thing not a real wold experience I used matrix in a tank 80 gallon cichlid heavy stocked tank and definitely worth the cost now that being said also used lava bbq rock and took a year instead of 6 months if your not feeding the tank your not getting anaerobic that MATRIX Builds on so heads up seachem does work and ill do the challenge any day hit me up seachem and yourself I'll start a new tank and use seachem products and will gautee prove you wrong or the tank will be yours sound fair ?
LOL. Seachem will be very pleased with your experiment because they most certainly don't like everyone using their product as an algae killer when it's marketed purely as a liquid carbon for plant health and growth.
Damn no comments on this?
Nice to see such great experiment. But let me ask one simple question. When we are speaking about Nitrogen (N), I'm not sure that any kind of established filter-media (full of bacteria) will remove and decompose Seachem Nitrogen into Nitrate and Nitrite. Simply because it's not pure organic Nitrogen. Just read about it, what formula they used. I'm thinking that Seachem Nitrogen is fertilizer used by plants. Only organic waste would be used in nitrogen cycle in order to get Nitrite and Nitrate, but not Seachem Nitrogen. I think I read about it somewhere... Can you try to add a water with organic Nitrogen, Nitrate and Nitrites and try to remove it with established filter-media? However I assume most of industrial products are there just for make us to buy it, and thanks again for this nice experiment.
What about a second aquarium without matrix for control? So during the time of the experiment we could see what happened with and without matrix?
It's not really necessary. The inability of nitrates to be removed without water changes or plants from a normal aquarium setup is well established fact so it makes a control somewhat pointless.
thank you for doing the test, much appreciated.
if I can see the flow rate of the water and really look nice ! it mean alot of Oxygen there ... slowing the process and help to kill nitrifying bacteria
It seems to work better with fish as between leftover food and fish poop the pores get clogged, then creating anaerobic condition in the clogged pores for anerobic bacteria to grow. If the pores don't get gunked up, then there will be minimal if any anaerobic conditions.
This matrix was taken from an established tank many months old with plenty of fish and plant waste. The truth is it simply doesn't work as advertised. I'm sure you can contrive a scenario where there's super low oxygen and get some anaerobic bacteria to grow but those are real world situations or how anyone actually uses this product. Also, if you did have a situation with low enough oxygen you really wouldn't need the matrix at all.
@@underwaterjungle Ahh, interesting. That's a shame.
You started by adding 10 times more Prime than you said and should have. Not sure how scientific this test will be...
Hmm. I didn’t know about cleaning the plants. Thanks. I have a special needs daughter who has started with an aquarium and it’s been educational for her.
I did try aswell for about 6 months and not working at all. West of money and stress.
Your plants are unhealthy if theyre eating them
You start with the misconception that it will remove nitrates from the start. Same as with other filter media that provide areas for anaerobic denitrifying bacteria, it needs time to actually eastablish a sufficient bacteria population. This will take months, not weeks. It highly depends on flow rate, oxygen levels and media volume, too. This is not a resin or chemical adsorbtion process. Please make sure to do a little research prior to conducting an experiment and potentially misleading viewers, thank you!
Kitty litter for anoxic filtration works better than this.
What about seachem denitrate?
Good question. I did not explicitly test denitrate. It's my understanding that it's still pumice stone just smaller rocks. Seachem themselves claim you need very slow flow for it to work; so essentially a contrived environment that wouldn't really exist in any normal aquarium setting.
So right! It can be frustrating when something specific unvanted takes over, or tries to. I have been unfortunate enough to have introduced some illness into two of my tanks from a specific shop. I've lost four Corydoras concolor, four Microrasbora erythromicron and 1.1 Endlers. 😢 I'm pretty sure it's nematodes or some other internal parasite 🪱 Fingers crossed I am treating the right thing! I hope your BBAs and the rest resolves soon. 😊
Great job!!........New sub :)
Thanks for the sub!
Looks great
Yes it does reduce nitrates after the bacteria has grown for 6 Months. But it reduce nitrates on a relatively low level. It is great to use it against nitrites and ammonium. For Aquascapes it is a nice filter material because of low reduction of nitrates.
Did you even watch the video? I show it does nothing against nitrates.
@@underwaterjungle the bacteria which reduce nitrates needs up to 6 Months to grow. Did you even read my commentary?! And did you read the instruction manual of Seachem Matrix?! Calm down a bit. Your experiment is incomplete, I‘m sorry! 🤦🏻♀️
I have been keeping fish for many years and have never heard of such things.....LMAO 😆🤣 Um, probably guilty of all 5 things at least once.
I've had Seachem matrix in my saltwater aquarium for 1.5 years and it has not removed any nitrates. Hmmm... *sarcastic*..maybe the bacteria is still growing? I have 4L of it for a 100L aquarium. Just use it for the purpose of any biomedia and not for the purpose of removing nitrates because it's not going to do any of that!
Exactly. It's decent biomedia at least.
@@underwaterjungle When I first added it into the water, I saw tiny micro bubbles coming out of it. So indeed it is porous. But to be honest as it's only effective for removing ammonia and nitrite, it's providing the exact same fuction as pretty much all biomedia. So I really don't know how "effective" it is actually. Like will there be a difference if i buy a really inexpensive biomedia online compared to this? i.e those plastic balls and ceramic media. The only real positive thing I can say as a hobbist is that this media doesn't breakdown unlike some which would crumble. Then again there are lots of inexpensive media that doesn't break down also. The rest of it's claimed benefits we can only trust as we can't really prove. I feel that in today's mordern world, you can't really just trust everything you read anymore including those from name brands and expensive items. You just have to do your own checks and take their claims with a pinch of salt as everything is a form of marketing. Sales vs Belief vs Truth. Thanks for reading, I just had to rant... Thanks for your video! Purigen didn't do anything for my saltwater tank also haha...
@@youronlycow I'm always down for a good rant! I entirely agree with what you said. It's really no more effective than simple sponges. What I do like is it's nice grabbing a handful of established media and seeing a new filter/tank with it to jump start things but beyond that..meh. I bought it specifically to reduce nitrates in a tank I was having problems with and it completely failed. I doubt I'd ever buy more. I have had similar failures with purigen to reduce nitrates but purigen is great at removing tannins however.
Gorgeous shop. I need context tho! Do you have property in CR?
I live in Costa Rica but just a renter.
@@underwaterjungle Muy Bonito!
Thats was really dope
What kind of substrate do you use ?
In this aquarium it's a Dymax base layer capped with silica sand. The back part is elevated with lava rocks in mesh bags under the aquasoil layer.
imo, the nature style of fish keeping dont make a whole lot of sense. In the wild, displacement of water happens very regularly. Ponds, lakes and of course rivers discharge loads of old water from evaporation and intake through surface run offs and rain. Which is why aquascapers change a lot of water. This removes debris, organic matter and other particulates in the water column, which ironically mimics rivers, with high turnover rates. Livestock: Also, the ratio of water surface area to fish is enormous. Say in context of our aquarium, could be as high as 10 gallon per fish. If we want to mimic nature, even for still water and ponds, water change is still necessary to mimic nature. Substrate: To mimic deep substrate, we would probably need more than a couple of inches, as in the wild, it could be several feets deep. The elitist nature of no water change and walstadist to preach their au naturale style is ironically not natural. In the wild, nature is not as contained as our glass boxes. It is constantly affected by temperatures, climates, weather change and fauna (birds, mammals and other inhabitants). Its a dangerous slope to preach as a fit for all solution, as some fish keepers could have high metal content, thus needing conditioners, or high calcium content, which accumulates over time. What i do agree with nature style keepers are that they do their own in depth research and studies to back up their claim. We as hobbyist should do our own, and realise everyone on KZread has an agenda to push, monetary or otherwise (fame etc.). So we should take everything we consume with healthy scepticism and apply ourselves
All excellent points. Thanks for the comment. I agree with you. No water changes feels entirely unnatural. Sure there is probably some stagnant puddle trapped in a cave somewhere entirely isolated from incoming water but it is definitely an edge case not the norm. I really like ecosystem aquariums but they lose me at no water changes. I almost think people aren't watching or understanding their fish much to not notice they really do love water changes. There are breeders though who don't do water changes on their breeding tanks to induce fish to spawn. It mimics the dry season when many species spawn. The fry hatch and move on as the rains start so breeders quickly move fry to grow out tanks where they do water changes like normal. It promotes growth. I enjoy water changes. It's part of my weekly maintenance ritual. It gives me time to ignore everything else and get my hands wet.
Yes, conversely water changes also induce spawning too! If you see most no water change or filterless setups, plants mostly survive rather than thrive. Though most live stock seem to do fine visually. I suspect plants are like sponge filter, where their nutrient uptake is diminish or even impeded once there are too much malm and detritus in their root level. Remember, our glass boxes are self contained, unlike natural water bodies where the new sediments are introduce through erosion, waterflow, run offs etc. replenishing the substrate level while our substrate remains the same in the tank’s entire lifecycle. Also, there are other hormonal and byproduct from respiration by livestock that are not detectable in test kit, which i suspect may saturate the water. What I am trying to say is, if we were to displace “old water” in tanks and “new water” in tanks, both with same chemical compound and parameters, the livestock can notice the difference, and some will induce spawning.
WOW... watched that video 10 or more times in a row
great video...a pitty you don't have more followers. you're doing a proper job man and in my opinion, more of this "fan-scapers" should see you articles. thumbs up
Thanks! It's always great getting positive feedback. I'm glad you are enjoying them.
thanks for infos but your own tank doesnt look crystal clear!
Right...
I think Matrix works best in canister filters based on what I have seen from these tests people of done.
I do intend to redo this experiment again sometime in the future with a canister full of Matrix. Maybe we'll see different results from that one.
@@underwaterjungle It should be interesting because in a canister filter it has no light exposed to it at all and it can hold a lot more media but also I'm sure there is a difference in the oxygen levels because it's not exposed to air in the same way. It's essentially pressurized in a way. I don't know if that reduces it much or not but I know high pressure areas like high altitude have less oxygen in the water. So maybe it reduces in oxygen in the filter and oxygenates as it comes out. Maybe that has an affect on how anaerobic bacteria grows in the center of the matrix in a canister filter or maybe it has more power passing through it to push it out of the center so that it can have an affect on the water passing through it.
All excellent points! Higher pressures inside a canister should actually allow an increase in dissolved oxygen levels rather than a decrease. Higher altitude have less oxygen because atmospheric pressure is lower. That being said, there so many different variables between a canister and a HOB that it certainly justifies further investigation. Hopefully I'll be ready in the next few months.
I had it in my sump for about 3 mths my Nitrates were about 20 ppm had 2 do a water change to keep nitrates at bay put in in a canister filter running about 30 gph within 2 mths my nitrates are reading 5ppm or lower maybe cause im forcing water thru the media im not claiming 2 be a scientist but been in the hobby over 30 years that being said it worked in that manner for me didnt do anything else at all besides change filter pads
I'd wager changing filter pads had more effect than than the Matrix did. There was probably a nitrate source built up in the pads so changing them caused your nitrates to drop. There's quite a few extra variables in a live system that cause people to incorrectly conclude it was Matrix. This is why I tried a more controlled setting. I will rerun this test eventually with a whole canister of Matrix and see if I can get better results but I'm skeptical.
ty!
You have NO clue how to keep fish and a healthy tank. People please don’t listen to him. Water changes destroy the health of the tank and fish. Go to Father Fish on KZread and see the proper way to set up a tank with dirt and sand substrate. You will literally only have to top off water from evaporation. Good luck to anyone who listens to this guy.
I'll keep your disrespectful and ignorant comment up for educational purposes. Water changes have been a staple of the hobby and for professional breeders for decades. Now suddenly they kill fish? My next video will deal with this issue. Maybe you'll learn something.
@@underwaterjungle you have been brainwashed by the big box stores just to sell more and more crap to make money off of the hobbyists. Please do me a favor and watch the videos from Father Fish and get a different perspective on the proper and healthy way to keep fish for years. If you have a balanced food web tank your fish will be healthy and happy. I have multiple dirted with sand cap tanks which are also heavily planted. My 55g community tank has approx 60 small fish and it is filterless for over 2 years and all I do is top offs from evaporation. The last time I did a water change was about 7 months ago and I changed 5g of water. So please look in the mirror and learn facts of keeping fish healthy before calling someone ignorant!
Beautiful aqarium pozdrawiam z Polski👌
Thanks! Witaj na kanale, Polsko!
A fresh and so clean clean tank kills fish. Nature is dirty.
This view is just incorrect. There are many different ways to keep fish alive and healthy. I'll be diving into this more in my next video so stay tuned!
