I can put the syphon break on the end back on, no problem, none of that pipe is glued, I just took it off because it didn't seem to do anything.

What do you mean by a bubble trap? Do you mean putting something like bio-balls in that centre compartment?

Thanks,

i am not sure there is enough air coming out of the drain to annoy the pump that much. besides you have a little bit of leeway since you are running SW. SW is thicker than FW so the bubble could just be lowering the viscosity to normal FW. an easy way to test this is to try it and if the temp of the pump goes up, than bad idea, if it stays the same or goes down than good idea.

a bubble trap is what i was trying to explain above. it is a larger diameter pipe that extends below the sump water level, nearly to the bottom. this allows the water to slow down significantly allowing bubbles to evacuate to the top. they will then be removed by the Tee above it on the drain.

Ok, what I will do is put the T back on, and submerge the pipe all the way to the bottom of the sump. I could go up to 1 3/4 pipe from 1 1/2 but that is all that will fit, do you think it is worth doing?

I will keep you posted, the good part is that since I already used that pipe in the sump it shouldn't effect my skimmer. I just put the 45's on last weekend to clean up the look a little.

Thanks,

sounds good. if you can go up a size than do it. it really will help a lot. it is much harder for the water to pull the bubbles along with it as the speed of the water slows down due to the wider pipe.
