I have 125 g tank and am having problems getting my zoos to open up as well as keeping Turbo Snails alive. Most of my water parameters are within acceptable levels, I have changed water until I am blue in the face....15 gallons per day for the past week. I recently read that zoos can be sensitive to high alkalinity levels.....this is the only test that has come back on the high side. I am showing 16-18 dkh
and about 480 on my calcium test. Could this be my problem, and if so what should I use to reduce my alkalinity? My salinity is 1.022, Ph 8.2, 0 Ammo, 0 Nitrite, 5 Nitrate, Temp 78. Thanks for the help.
