I've been trying to raise my nitrates. They've been in the 0-1ppm range since I started the tank 3 months ago. It's a 40 breeder and I have 4 fish. Two clowns about 1.5" long, a filefish about 2" long and a long nosed Hawk fish about 3" long. I've been feeding heavy to try and bring the nitrates up but that's now working. Should I take my skimmer off line?
