Pin point Ph & zoo issues
I have two problems right now.
-The first is that my favorite blue zoos have 95% dissappeared! I don't know why because all of the other zoos in the tank are fine. I've ruled out predators because the colony sits right beside another type that are thriving, and I find it hard to believe that a predator would be picky about the color of zoo they would eat. Am I wrong?
-The other issue is with my Pin point PH monitor. PH read 8.42 on average about a week ago. Bought some calibration solution and tried to adjusted it, I got it as close as I could, then my PH read 7.98. Out of curiosilty I got a different kind of calibration solution from a friend and re-tested last night. It was way different and after getting it as close as I could my PH now read 7.67. I did the ol' lick test on the battery, lots of juice left.
Is my probe worn out? Its about 1.5 years old now. Also, I leave the probe in the sump and only turn on the monitor when needed.
