pH=7.8 — Ammonia=0.25ppm — Nitrites=0.0ppm — Nitrates=50ppm

I have been doing some water exchanges and this has lowered the Nitrates. More will need to be conducted. The pH rose some probably due to adding the new water. I have been using city water, but have it oxygenated for several days with an air pump pumping air into it through a diffuser stone. We have just lost our second feeder fish in the system; RIP “Mohawk”. A couple weeks ago we found our first floater, “Charlotte”. So far the girls have not noticed Charlotte missing.
