Most usually the pH between 6 and 8 is fine... but as long as it is stable, which it would not be if your KH is too low for instance or if you have huge accumulations of organic detritus.
15-20 ppm nitrate is fine.
Any ammonia reading and nitrite reading over firm zero ppm is not fine. Use a test tube filled with an ammonia-free water (tap, bottle, filtered) as your reference because 0.25 ppm is not easy to tell from zero ppm by using the color chart.
We are not here to flame you or point fingers and call you names or even judge you. We'd be shooting ourselves in the foot. We have all been where you are now and find ourselves there every now and then even after decades of fish keeping, so what? We all keep our fish on life support. We keep water really, not fish. If you want our help, Niki is right, you gotta read the protocol and our posts and then give us all you can.
... If you cared enough of course and willed. I, for one, have no expectations, whatever, and I am just glad to have you as a peer on MFK.
