I had LFS test my water yesterday. As I figured, Ammonia 0 - Nitrite 0 - Nitrate 80-90 ppm. The only thing suggested was to raise ph slightly. ph tested 8.0. This was my fault as I did so many water changes in the past few weeks trying to control the Nitrates. So I'm back to square one. The more people I talk to on-line or in person the more frustrated I get. No one can give me any idea what is going on. Some have even told me, (don't worry about it the nitrate will not affect the tank that much.) Short of trying to find a Marine Biologist, I do not know where to go from here.
