Hi everyone, I've been keeping a mixed reef for 3 weeks approx with a load of mixed coral frags. While all my calcium and magnesium levels are spot on my alk/kh has dropped which I expected. My weekly water changes are being done with water that brings kh to around 7dkh I'm aiming to reach approx 8. Now it reads about 6.9 after water change and drops throughout the week to about 6.5 before a water change. Now I have a new auto dosing pump which I'm ready to try out. Can someone pls help me as how to figure out exactly step by step how to work out what ml to dose and when to dose. The tank is 350litres with around 100kg of rock so I'm gonna safely say I have between 200 and 250 litres actual water content. Can someone help pls, any help would be much appreciated
