Hold old is the test kit? I would test again.

With the setup you describe O2 should be high enough. No Co2 at the moment correct?

EDIT: Excel shouldn't be a problem. I've gone overboard with dosing without harming fish. Although it's really not necessary with Co2 as it's liquid carbon. How many bottles of Co2?
