Need help with microbubbles !

[Jim Barry]

I just finished the plumbing in my new tank and filled it a couple days ago.

I am now having huge problems with microbubbles.

The tank is on the main floor with the sump in the basement. I have 2 external overflows with Durso's. The 1.5" drain lines run down to the basement and follow 2- 90 degree turns before reaching the sump. The waters enters into a pail in the sump and then overflows to reduce the bubbles somewhat. In the sump,there is an eggcrate partition with filter material just before the exit to the pump.

The problem is the the force of the water when it hits the sump. There is quite a bit of turbulence, causing more bubbles.

I am not sure if I should be building some sort of baffles ( I don't want to drain the sump ( ), or if I can put more turns in the piping to reduced the downward pressure. Has anyone got any thoughts on this?

one other thing..............

My Dursos are also very noisy. The "flushing sound" is because the water level in the overflows keep rising and falling. I am adjusting the air intake on the top of the durso's, but it does not help maintain a steady level of water in the overflow.

Thanks

Jim

Here are some pics of the sump....
