I thought you decided not to mess with the pH?
I did, but then I really wanted to try the PH Down before I added the stock, so I did and it lowered it and stabilized at that level. So that's when I added the fish. I have a system worked out now where I have an extra bucket I use to do refils from evaporation and later for water changes. In the system I add new water to the bucket from the tap, then add my water conditioner to it, put in the PH Down, and let it hold for a few mins before adding it to the tank water. So far it is working, my PH is not fluctuating and the little guy seems to be really happy and active.
