Gurgling POC overflow

[Doug]

Its just the large model Coralife skimmer. Skims well, esp. for my small tank but pump vibrates and hums noticeable. Perhaps once I silence the air intake it may be better. The price was right, {a trade} and I was the skimmers original owner, so figured I would give it a try.

Hmm. A nice quiet BK mini may do the trick.
