How to dose RO water for planted tank
Үй жануарлары мен аңдар
In this video I tried to make the information I explain easy to understand on this confusing concept. If you need measurements for a lesser or a greater amount of water all you need is some basic multiplication or division. Please don’t hesitate to leave any questions you have in the comments.
Interested in the under water world but could use some info before creating your very own Aquascape?
Here’s a link to my play list. I add videos every week and getting better every time!

Really useful video. Simple and straightforward. Thank you! I can scale this up for my 80 litre barrel and always have water changes ready to go.
Tip for the equilibrium take a bit of the 5 gallon ro water and boil it, to that add the desired equilibrium and dissolve it!! Otherwise you’ll find little chunks of the powder at the bottom of the container that never really dissolve fully
Great video!! Very easy to understand info and 'recipe'. Very helpful!
Thank you for this. This was straight forward and exactly for the qty of water I'm wanting to mix up at a time.
Thanks again for simple clear instructions. Wishing you a speedy recovery next week!

Thank you for the clear instructions.
Cut some parchment paper to use as a weighing paper on the scale. Refold in half and then flatten to weigh. You can then fold and pour.
WOW! Thanks man. You are the only one online that shows and help everyone on this. Great job!!!!! Cheers!
thanks for the great video. I have super hard water. (off the scale hard). I do have an R/O system. I have been adding just a little well water to my R/O. It is still way too hard. This will be so much better. I ordered all the products already!
Thank you for sharing! This is really helpful! (I use a digital spoon scale so I don't have to mess with lids, etc.)
Oh man thank you so much for this!
Hi thanks for the vid! As an added tip you can use the inside of each cap to measure just tare it out before you start that way no mess on the scale.

Great video…. It’s good practice to pay close attention to the KH as 3-5 is ideal….get it to low like 1-2 will cause PH Rollercoaster swings.
Thanks so much for the video
This really is appreciated. I e been struggling trying to properly remineralise my to water.
This video is exactly what I have been looking for for a while. Subbed. Keep posting content like this! How would you go about dosing this with a doser like a DOS Neptune? On water refreshes how do you adjust the dosage for the new RO water?
Thanks
Good job! With this set up, could you share kh also? Thanks.
Thank you so much. I have been searching high and low for an easy explanation and demonstration. I am filling a 32 gal. Brute container with 20 gallons, so I was able to work out the math on the quantities for this. Question: When trying to hit 6.8 Ph. if the quanties given don't quite get me there, can the Acid buffer be added a small bit at a time to hit this level? Thanks
Nice vijeo...
Please do a video on remineralizing RO water ( barrel ) in the aging process for discus tank. Anything more than 4dKh stress the discus.

So, based on the chart on the buffers it says to divide kH of your tank and then it also has a “add this much to lower pH.” What was your starting number to determine your measurement?

Question... couldnt you just use a mix of RO water with declhorinated tap water to re mineralize it? For instance, a 10 gallon tank would use 8 gal of RO water and the remaining 2 gal tap water?
When water evaporates, do you top off with RODI water or that conditioned water?

Dang! Wish I’d found this vid a month ago! Our well water is liquid rock with a hint of ammonia so RO is the only way I can have a tank.I had to figure out the math myself for a 3 gallon and even just 1 gallon because water changes are so small.

I don't see why not. Preparing 5 gallon at a time you will have 4 months worth of water changes assuming that you will use the first one right away. You just need to keep it in a sealed black bucket to prevent any algae bloom.

You can certainly adjust the measurements to meet the parameters that you prefer. My main goal in this video was to give a base knowledge on dosing RO water. You could use less equilibrium to possibly meet this goal however it does depend on how dense the planting is.
The company should pay u for this
Using acid buffer and alkaline buffer at the same time is pretty funny. Seachem has you buying lots of unnecessary chemicals. Alkaline buffer increases both pH and kH. Guess what acid buffer does? Lowers both pH and kH 😂. Its easier and cheaper to just cut your tap water with RO water and figure out the best ratio than to keep buying that stuff.
We use fluval stratum - a buffering soil. Should we stil do the alkaline/acid parts? Or just the equilibrium? Our RO (not RODI) water is already around 6.5ph

I'll be honest, I never really considered that. I personally do add the buffers and from what I understand that is the correct way. The directions for the mixture are referring to a planted tank so I have full confidence that you should definitely use the buffers. For sure the alkaline to keep the PH from dropping to low.

CO2 injection will change the PH, but we have to consider the number of plants available to use the CO2 and if the plants have access to the needed nutrients, plus the age of the aquascape. We should also consider the size of the tank and if we are using the correct amount of CO2. Larger tanks are more stable so I would rather everyone be mindful and watchful when using CO2 in a smaller tank.

Equilibrium dose have most nutrients that fish and plants need however you will still need to use liquid fertilizer for the plants if you are using injected CO2. At that time I was doing water changes every day because it was a new set up and the soil was still leaching a lot of ammonia do to high nutrient content in new soil. If daily water changes are ignored algae will appear

I know the buffers state they are for RO water mostly, but they do mention you can use them with normal tap water. My water is very low in KH about 2dkh and PH is around 7. GH is 5 or 6 I already use equilibrium to buffer my GH up a touch but I recently bought the other 2 buffers I wanted to try and target a KH of 4-5 and a PH of 6.8 ish do you think that’s achievable without using RO water? I’m quite comfortable converting my KH from Dkh into meq/L for the seachem dosing calc and adjusting slowly. From my understanding to target that KH from 2dkh to say 4 Dkh will raise PH considerably so I’d need to adjust that 2 to 1 with the acid buffer. Is my thinking on the right path or way off?
@novaaquatics9137
Жыл бұрын
You can achieve this, but for all the alkalinity and acid buffer, you add, it will also raise your GH and TDS. With tapwater in a bucket add the alkaline buffer until you reach the KH you want, and then slowly add acid buffer to reach the pH you want. After which check your GH and TDS to make sure it is safe.

I have a moderately heavy planted tank. When your target ph is 6.8 to 7.0 I assume that is without any CO2 injection. For example, since I inject CO2 I would measure my ph level at night when there is no CO2 being injected into the aquarium. During the day, if my ph starts at 7.0 and I'm injecting 30ppm of CO2 then my ph will drop to 6.0, If I just have some community fish do I need to worry that the ph is dropping that low?

It’s very much depends on what the inhabitants are living in the tank. For example, shrimp require different remineralizer’s and buffers. I believe they use a salty buffer.

I do want to make it clear that the ratios mentioned in the video are for RO DI water and has absolutely nothing in it except H2O. If you are cycling a tank with RODI water or RO Water I would add the needed mixture. And yes you can add the mixture to the tank after adding the water if you prefer. I would add twice the ratio I mentioned in vid for 10 gallons.
This works well but I don't get your math. If your goal is about a 4 dkh, then that means for 5 gallons your multiply factor is 1.43 [4 ÷ 2.8 = 1.43]. You then would multiply this 1.43 by 1.5 [5 gallons is 1/4 of 20 gallons therefore if 6g = 20 gallons then 1.5g = 5 gallons]. 1.5 × 1.43 = ~2.1g of alkaline 2.1g alk ÷ ~ 1.8 [from chart to reach ph of 6.8] = ~ 1.2g of acid So this means 2.1g of alkaline and 1.2g of acid. Also equilibrium suggest 16g per 20gallons for 3dH. So for say 5dH in 5 gallons wouldn't that be closer to 6.5g of equilibrium? I'm not doubting your dosing suggestions as I've used them but why so much lower than instructed?
