The method of testing the tap water was to let it sit for 12 hours in a bucket with an air stone and then test all the parameters. Will a Ph of ~8.3 have a negative effect on my Otos or other species I want to add?
I understand wanting to use only additives needed by necessity, but are there other things I can do that will allow the water to maintain a close to ideal condition? Out of curiosity and quest for knowledge, how do the pros with very sensitive and picky fish do it?
Also, for the record, I purchased the stress zyme on accident and am only using it until it runs out. I hate wasting anything.
