Well now the ph is rising too high. Before Kalk reactor it was 8.0 to 8.2 after kalk reactor it is up to 8.8? I go through quite a bit evaporation due to halides and fans but what do most people do to fix this? My tank is a 180 and is an upgraded tank from a 65 gallon. The 180 has only been running a couple weeks. Livestock is about 12 sps frags and 5 different branching lps colonies. Right now I have pulled the hose out of the water allowing the kalk water to hit the air making it much less effective.
