And yeah I should have done a lot more but I trusted he knew what he was telling me cuz his tanks are beautiful. I could have misunderstand what he said to so I'm not going to just through him under the bus. I got the kalkwasser from jl it's the bigger container they sell. I had around 12 tbsp in 13 gallons of ro/di and was thrown in over night with my ato

Your ato fills 13g of water overnight or 1.3. if so then there's your issue along another of why so much water , also 1 Tsp per gallon is the Starting dose not tbsp and make sure your ato isn't dosing too much at a time or besides what you got visibly you could get get ph spikes as well.

If your going to run Kalk make sure your dosing any other cal/Alk supplement and test your water for a while to make sure it's doing it's job or isn't.
