Gurgling POC overflow

[Doug]

SO, first time I run my 30 cube w/ its new sump and stand, the old sand leached something or the pump I was using did. Anyways, lost several of my sps. Basically all my Snappy frags.

So moved the rest to my 20g before I lost it all. Took my time and redid lots of work on my stand/sump and cube. One was dumping the overflow I had build and going back to Duraso. {I have no room for a Herbie}.

Now I have been building and using Duraso,s since Rich first showed us how. So this time, I run the cube for 3 days on fresh water first to check everything out. Just dandy. Duraso is as quiet as can be and works like a charm.

So, finally moved my stock back to my cube today and the overflow stinks. same problem others have. Runs fine then sucks down and gurgles then fills up again and so on and so on.

What the heck. Fresh water is different than salt for an overflow. Sheez, all these years using one and I have never had the problems others mention with them, until now. Is that because I read about them or what.

I quit.
