Help with my DIY skimmer

[tava716]

Hello,

My tank is 10 weeks old. 90 gallon with 10gallon sump, and this DIY skimmer. 3inch pvc. 4 feet tall (can't) see whole thing in photo. Only getting what you see in the photo for skimmate every couple of days. running 2 3 inch limewood stones with a double output pump per stone. Can anyone see an issue with this?. 3 damsils, 1 royal gramma , 1 brisstle star, 55lb live rock. Should I add 2 more airstones (being that I can run 4 with the 2 pumps if I need to)? Water level is at the bottom of the piece of pvc fitting where it starts to taperoff. Please advise.

thaks a lot folks!!

Try backing your water off a little to wet your foam up.

Seems like a better, single air pump, and better air stones would produce more foam.
The water level is what makes the foam go over the top into the cup. So a higher water level would work better than a lower water level. IMO.
