I have a new 30 gallon tank with a canister filter, bubbling fish statue, bubble curtain, and soon I'm putting a small powerhead in near the surface. I have 5 goldfish of varying smallish sizes in there temporarily until I move. My question is whether its possible to have too much oxygen in the water? What are possible problems that could arise from overly oxygenated water? Mold?
