I’ve had this Oxydator for a few years but haven’t filled it in a year. Last night I decided to get it running again. When I finally got it open because of encrusted corals I noticed it was full and the plastic was black. I rinsed it out and filled it with 12% hydrogen peroxide. It was smoking a little. I put it in the tank and a lot of bubbles were coming out and didn’t look right so I pulled it after 5 minutes. I woke up this morning to a cloudy tank and a fishy smell. What should I do?
