Question

Answer
Dear George,
I think you are fine with what you have now. There really isnt too much worry with too much oxygen. It is very rare and I am not sure if it is possible to have too much oxygen in the aquarium. I haven't heard a case yet of too much oxygen in the aquarium.

Plenty of oxygen is essential for all fish. And you have some good working filters that should do the job nicely for you!

Best wishes and I hope this helps!
Happy fishkeeping!!!
