Captain Hemo, The powerhead doing that is an 802. the output is in first chamber.
Marc,
With the snapper at 1/3 on both lines, there is alomst no flow. yes, after a day or two the bubbles would dissipate. but there would be next to no flow in the tank.
there is no fluval running on the system at all.. in the pic its just hose running from a 802, through a uv steralizer, and back to the tank.
I had a lengthy phone call with Marc from Hidden reef already, and tried some stuff. It was hard because obviously if anyone could "see" the setup, im sure they would see the problem, or have a great fix to it. He suggested some foam blocks that are used in the sumps, and it was just accidently forgotten, so i should be seeing that soon.
I am unable to find the socks to fit this sump here in kelowna so im gonna have to order them up.
Microbubbles do go into the third chamber, however, not because water flows over the first weir, they just go through the entire sump .
Im positive there is no leak in the pump side of the plumbing. I used an eniter can of the weldon 705 yesterday.
My main tank flow is now the problem. when i bought this, i bought it because i did not want to use power heads anymore, and was told this would be the route to take.
Arghh. the frustration.....
