Ok so I have two tanks, one is roughly a month old the other is about 3-4 months old, both tanks come out between 8.0 and 8.2 PH on my API master test kit. Yesterday in order to get my first fish for the newer tank I tested at home then I took a tank water sample to my LFS, they tested using an API master test kit (at my request) and the result for PH was 7.8. Is it possible my test kit is dud? Or could my PH have fluctuated that much within half an hour of each test being done?
