I dose Flourish Iron about only 1-2 ml every other day. But I screwed up, and accidentally overdosed my 30 gal medium planted with about 15-20 ml by complete accident! And now it appears to be a bacteria-bloom severity of clouding. So, will a chemical HOB filter media assist in eliminating the cloudiness? If so, which media? Purigen? I mean I could do a water change as well. It's been cloudy for about 2-3 days now ever since I halted the iron dosing, out of sheer hesitance. Thanks for your help everyone!
