silent overflow

Brandon42 · Oct 31, 2015

my tank is only drilled with one hole is there a way to plumb this where the water will run quietly?

not really bud. at this point all you can do is slow or speed up your return until its quieter, but its going to be a constant battle. I've tried to run a single overflow in the past and I will never do it again. your best bet would be to get another hole drilled. itll save you a lot of issues in the long run.

No way to run a herbie but to one pipe?

Dtackett · Nov 1, 2015

no a herbie requires 2 pipes. 1 pipe the only thing you can do is put a gate valve on the pipe and slow the flow, or match your drain and return. its not easy.

Any of the standard single-pipe solutions (Durso, Stockman, Maggie Muffler) will help, sometimes a lot. But you'll never get them completely silent since you always end up with some air getting sucked down along with the water.

You can absolutely make it silent. A modified Stockman standpipe with a piece of airline tubing stuck down in the flow and slowly adjusted can make it totally silent. Been doing it myself for 13 years now in my 100G with a single 1" Stockman and a Waterblaster HY5000 return running unrestricted from the 30G sump. It can be done with about $5 in PVC parts.

would you post a pic or 2 of this? ive never seen a silent, single drain overflow, that didn't require frequent adjustments to maintain proper flow.

Stockman directions are on Richard Durso's website. The only change I make is to drill a hole in the cap large enough for a piece of airline tubing to fit snugly. I cut a foot or so of tubing then slowly stick it down I the standpipe about 1/16" at a time until the flow picks up and it becomes totally silent since it has the optimal air/water mixture. Haven't moved the airline up or down in years. Lots of reefers use the same setup.

when I read this I thought about the glass holes kits!
