Had mine for couple years, been a awesome reactor.

This is the model I have been thinking of going with. Thanks for the tutorial Deven.

Good video, Devin. Sometimes, it's the Suttle things that help you to understand. In this case, it was looking at when the ato pump was running to adjust the kalk dose. Thanks again for helping me understand. I know Robz is into the kalk slurry. I'm not there yet, but enjoy learning.

awesome! so far its really nice!

i used that model before I went full on slurry. It worked fairly well, don't over fill it as it can build up and become inert over time, stick to the recommended amounts and I yanked that 90 degree elbow as it was more of an obstruction over all. If you are in the market for a stirrrer, this is a good one overall.

@@scotttang6229 kalk slurry is dosing a constantly mixed solution of kalk. Regularly saturated kalk doesn't dose the white settled out kalk that didn't dissolve in solution. It doesn't fully dissolve because water has a saturation limit for kalk. When you constantly mix kalk you create a slurry that includes undissolved kalk. If you dose this into a high high flow area it'll dissolve into the water and be a more potent dose of kalk. A kalk slurry setup is more advanced and requires ph monitoring/controlling to use safely.

@@ReefDudes since it's really based off estimated evaporation rates I was putting in about a cup every two weeks. When I tried sneaking more in figuring that I could go longer in between I started to notice that it wouldn't deplete after a while like it was when I was putting less in. It would just remain as a sludge. I'd yank the unit off once every 7 or 8 months for a thorough cleaning.

@@scotttang6229 it means dosing a suspension of calcium hydroxide of 2-4% by weight instead of the normally saturated effluent that this unit would provide.

Other than the size being a factor, would you prefer the icecap or the avast. I am looking at both at the moment just not sure which one would work best in addition to my two-part dosing. I have a 100-gallon mixed reef. just in case you need that info

I'd love to learn your setup on how you get the water from your ATO to the stirrer, and then from the stirrer into the tank. I have your Apex program, but what do you have plugged into the apex that's being controlled? The stirrer, the versa pump, something else?

Hello Devin, how are things going with your kalk stirrer? How do you run it now? Are you still stirring 24/7? How much kalkwasser do you add to refill? Do you dose day and night? What is your ph and other elements like kh, calcium and mag?

Hi Devin, Do you think it would be ok to have your dosing pump pulling from the sump so you're adding saltwater to the reactor instead of rodi? My auto top off is gravity fed using a float valve so my sump is always at the correct level. Wouldn't this help keep the salinity the same all the time? Once the reactor is full initially with saltwater and the dosing pump kicks on, wouldn't it just be trading saltwater for saltwater therefore keeping the salinity constant? Looking forward to your thoughts on this.

@ReefDudes

2 жыл бұрын

You need to use rodi for kalk

Am I correct in the assumption that when you already have a calcium reactor in use that you reduce the effluent from the calcium reactor so as not to add to much alkalinity to the tank and then use the kalk to make up the reduction in the calcium reactor output to then bring the alkalinity back up to where you like and also bring up the tank PH?

@ReefDudes

Yes you reduce the carx effluent as you add kalk to keep it in balance

Hi, just curious, are you getting an improved ph with this one or the Icecap version? My system is struggling to push to 8.07-8.10 during the day and dive to 7.80 at night. That is with the KALK Mixer as well as recirculation skimmer set-up... I have since stopped the recirculation and just pull air directly from outside directly to the CO2 scrubber as of today...will monitor the levels, but I wanted your input

@ReefDudes

2 жыл бұрын

I'm not sure if there is much of a differance in PH in one over the other.. advantage of icecap is you could get it to be more of a slurry vs avast. big thing for me as i wanted the slightly smaller foorprint so i could add my 2nd carx chamber back in to help absorb more co2 from the carx

is this the type of slurry you want to dose? i imagened a more consistent milky mix in the entire container. would the Geo kalk reactor which uses a recirc pump not work for slurry?

Good afternoon. I'm writing to try and figure out why I can't get my PH up in my reef tank. I'm using the same setup as you with the Avast Kalk Stir but I all of a sudden can't get my PH to average over 7.5 even when dosing up to 10 liters of Kalk a day. When I first started the kalk the PH rose to 8.4 easily but now, no matter what I do I can't get the PH up. My skimmer pulls air from my attic through a BRS twin chamber CO2 scrubber. The windows in my fish room are open and my CO2 monitor in the room is constantly under 550 ppm. I have an air stone running full speed right below where the Kalk stir dumps into my sump. I'm out of answers or solutions. Do you have any idea what my problem might be? My tank parameters now are Alk 10.6, Ca 471, and Mag 1475 Thanks

Never used kalk but a question I’ve always had . Do you have to chance the kalk out or do you just keep adding more ? How long does it last usually?

Wast of money kalk powered that seats on the bottom does not need to move around. The kalk Leeches into the water and the power that seats on the bottom is nothing but waste.

As water gets pushed out its replaced with fresh rodi water which has more absorption capacity. At a certain point yes the powder will be exhausted and need to be replaced... Yes you could manually mix up batches and drip it.. but this is for the people who dont want to mix it up every few days. Depends how you value your time.. Time vs money!
