I'm just not sure. I just took apart the fan cover on the pump and put some padding into it where it touches the metal body. Haven't restarted it as I'm fixing a few spots where my unions needed to be "tightened".
If I can't get it to be quieter, I might take apart the return plumbing just out of the pump and try black spa-flex. The stores tell me it shouldn't be used salt as in salt pools, it degrades quickly. I'm also watching for the Blowhole 2750 pump as it might be enough to replace my Blackfin (with less watts and better head pressure abilities). I hear they may be out in March.
