So on Saturday I bought 5 honey gourami, brought them home, acclimated them to the tank (which had just had a water change), and released them. One looked bad on Sunday morning, and I could not find it Sunday night. Monday morning I found it dead, and Monday night a second one died. My LFS has a 3 day health guarantee, so today I brought it in with a water sample, as required. Ammonia 0, nitrite 0, nitrates 10, Ph 7.5 (as always), and Phosphate 1. They said my PH was way too high and the nitrates were bad and that I had to bring in a water sample next time I wanted to buy fish. They also said to go home and do a water change, which I planned to do anyway (I couldn’t do a water change before I took the water sample if I wanted it to be accurate). In reality though is there anything wrong with my PH? This tank consistently has less than 5 ppm nitrates, I’m guessing that the dead fish caused a spike in ammonia, which was handled by the fact that the tank was cycled and just left more nitrates than the plants could handle in a short period of time. Right?
What does the phosphate mean? Is 1 too high? What can I do about it?
