Waterbox 20 Cube AIO - SPS Dominant; Auto Water Changes

In my 20 gallon tank I do 5 scoops of kalkwasser stir in 5 gallon jug and dose it with a x1 kamoer dosing pump. Works great and I am even dosing even more alkalinity to boost it because corals are growing mad. Works grade I love the PH boost from kalk. I started with tropic marine all in one then moved to 2 part couldn’t balance it well. Moved on to kalkwasser and used 2 part then found calcium to be really high so now just use kalk and alk. Kalk stays pretty steady. I started with 3 scoops of powder. Slowly increased to 5 scoops of kalk. 1 per gallon as stuff grew. Everything super happy.

Made a mistake with the kalk - my pH jumped from 6.4 on Thursday to 7.7 today (+.25/day in 5 days) and I looked at the calculations and realized that I used a tablespoon instead of a teaspoon, oops. Could have been a lot worse but re-made the kalkwasser and hopefully things will level off.

Kalkwasser has a maximum concentration at a certain point (usually 2tsp per gallon). So you don't have to be super exact about how much you mix. I usually mix about 5 gallons at a time and 11 tsp just for fun . What are you dosing with? A continuous doser, like the ecotech versa is the best option as it can run all day long no issue.
