I have been using API test kit and it was looking to me as though it was at about 8.2. I had a Chromis go on me so I took a sample to my LFS
and they rated with a pen and showed 7.5 which I was told was very low and advised to dose.
I am of the same opinion when adding any chemicals but given the advice i thought it would be ok
Both corals seem to be ok now as they are slowly coming back out but still was the advice I was give good?
