I accidentally used some bleach with surfactant in it one time. The advice I can give you is to rinse it “extremely well.” I’d personally discard it. I rinsed mine several times until the water ran clear, but managed to loose a PBT 20-30 minutes after introducing it to the tank. No other fish were affected. Surprisingly the corals did ok too. Didn’t have any SPS in the tank at that time.
You can save it, but you better rinse it and stir it about 20-30x or so in a large vat. Then the question becomes…is it really worth the risk, time, and effort?
Cheers!
