What are you adding to your tank?

I do almost strictly SPS and I add nothing other than kalkwasser. Water changes (IO Salt) and carbon dosing (VSV method) help keep parameters in check. When I started I used to dose everything but, unless I could automate the dosing (two-part dosers), it actually caused more fluctuations and hassle. And if I went away for the weekend? Everything would be out of wack. Ever since I simplified to kalkwasser and an ATO life has been great and my tank has taken off.

Agreed, another great solution. I have a small SPS tank that runs Kalk and it's doing great!


The only issue with this, for me, is you need to keep PH in check and the biggest issue is kalk can only go so far. Once you reach saturation (2 tsp per gallon of top off) you will need to supplement something else.

My 60ish gallon tank is keeping Cal/alk at 420/9 very steadily and I'm using 1 tsp per gallon of top-off.

P.S. I still have to dose MAG.
