Reef Ocotpus bb 2000 won't quit and I have checked the valve and it is working. Took everyting out of my sump and cleaned and repaired ( gfo refractor, carbon refractorand the blaster. Just re-started everyting and the blaster is going nuts. ALSO have a new naso in the QT tank and for the last day or so it has started to look like it is gasping...never shuts it's mouth. Till yesterday it has been 100%. This gasping thing happened to my last Naso after it has been in the QT for 12 days...didn't make it the 13th. This is also the 12th day that the new Naso has been in the QT. What am I doing wrong? Note: in both cases the Naso had been sharing the QT with another fish...........both of those fish lived. Need help, I am afraid to go to bed with the BB running this way. Thanks, Bubba:jumpy::jumpy::question:
