Well, I just tested PH (3 times, just to make sure) and I'm at 7.8. I just did a 20% water change this morning and I tested the new water getting 8.2. The only thing new I added was chaeto about a week ago. I've never had PH problems in the past. Always reading 8.2.
How dangerous is 7.8 to inverts? Just got a giant clean-up crew after getting my NO3
to an acceptable level, now this. Do I just do several water changes in the next few days to get it down?
Also, just dosed Iron if tha matters.
EDIT: Just tested with a better PH kit (SeaChem) - and I'm getting about 7.9. Tried to test Alkalinity but I"m not digging this SeaChem Alk
test kit. The color is not changing so either my alkalnity is really high, the test kit stinks, or I'm color blind.
