So I have a 60g cube with a 20x20x13 sump. I'm estimating around ~60g total volume. I'm trying to determine a good starting point for daily Alk/Ca dosing assume both are added equally. I'm using the BRS Alk/Ca mix it yourself stuff (not the brand new package version). Here are my Alk readings right after a water change 3/5 - 8.1 (day after water change) 3/6 - 8 3/7 - 7.8 3/8 - 7.7 It seems to deplete at ~.1dkh/day. With this as a starting point what should I be dosing in Alk/Ca per day assuming I want to keep it at 8.1?
