i have three tanks, that I have had running for a year and a half. Lately I have had some fish deaths, and some of my fish in my 30 gallon look a little off. I had a dead tiger barb, and a dead gourami within a week of eachother, with no sign of illness. water parameters are as follows;
ammonia 0, nitrite 0, nitrate 10ppm.
temp 78 degrees.
i feed a balanced diet and keep regular water changes. just bad luck? or could there be an illness that i can't see in my tank?

the fish died about a month ago, and now everyone seems fine, except one other tiger barb looks pale and a little lethargic, but still eating.

what is ideal or acceptible nitrate levels??

The gH and pH would have to be wayyyy off...something I didnt think of earlier, what do you feed them? If its something other then flakes, what is the source of that food?

It very well could just be bad luck. Do your fish seem off in color at all or acting any different from normal behavior?
