Kalkwaser

[Aquattro]

I used it for years as a super saturated mix (with vinegar) in my top off, no complaints. I had lots of MH lighting, so lots of evap, but it worked well. I upgraded to a reactor after this and wouldn't look back, but at the time, it was a good solution.

The problem I found with running it in a gravity fed ATO is it would constantly gum up the float valve that I was using. So I built a reactor and now I run it with a pump fed ATO system. Kalkwasser alone won't keep up with my calcium carbonate needs so I also use a Ca Reactor. The two complement each other nicely because the Ca reactor lowers the pH and the Kalk reactor raises it.

Good information, thanks

At this stage I am running a very low demand setup, but I want to get a system in place for future expansion.

I think I'll grab an auto topoff unit tomorrow and run it that way for now.

I can see the seasons affecting evaporation. It's dry here in the winter. So it evaporates faster obviously.

So the question is how do you know what to dose if you don't use it in an ATI setup?
