It's too loud !!!

The hole @ top of durso looks like approx. 1/8 - 3/16 .
The water drop into overflow is approx. 1" .
On the bright side I found my missing cleaner wrasse in the overflow !

figures that where he went my clowns love it in there, for future reference if a fish goes mia check the overflows and the sump one of those inspection mirrors comes in really handy for that. is the outlet below operating level of the sump. does the level in the overflow fluctuate much i'm pulling straws now

is your air vent adjustable on your durso or is it a hole drilled into the top.if it's just a hole ,try putting a mini ball valve on top to adjust the air

The vent on top of the durso is a nipple ! I could attach a piece of air line then control by pinching but I've been listening & reading & decided I'm happy with it !!! It's quiet but not silent . I think I'd switch to Herbies if I want it silent . So I can live with quiet right now & if it still bugs me later on I'll switch . Thanks for the input .
