Hey man, no need to quarantine in the reef. I just had the same problem after a tank crack. Use a product called medic for 10 days and it will not harm you filter bed, fish, corals or inverts. My hippo is spotless already. Get it at marinedepot.com. The chemists that make it are polyplab.com. Really a solid product and no I don't work for them. The active ingredients are metronozonol (flagyl) and peroxic acid. I probably spelled them wrong.

So was I but all is well in tankland and this saved my a*ss. Totally his call.
I am just saying what worked for me in a pinch. They are very accessible to discuss as well.
Nada, you can keep your skimmer on the entire time you treat your fish as well. I ran carbon (Rowa) in the sump for a few days after I finished to clear the tank.
