 Did you join the 2 1" pipes coming from the drains Did you use 1" pipe after join If so the 1" pipe won't be able to handle the flow of 2 1" pipes If the tank overflows when you open up the flow on your return pump the drains are being overwhelmed, 2 1" drains should be able to handle that volume What are the linear dimentions of your overflow? From Reef Central Mag 18 at 4' head with 2 90's = Gallons per Hour = 1115 Drain and Overflow sizes are calculated as Recommended minimum drain pipe diameter = 1.38 inches Recommended minimum linear overflow size = 17 inches HTH Dan

How are the baffles set up in your sump? How large is the pump compartment in your sump? You may have to redo your sump if that is the case.

The sump is 20 gal right. Did you add more water to the sump like I said to try. I think that is your problem.
Or you have the baffle to high in your sump. What is the height of your main baffle If that is the problem then tee off the pump to go into the return line. basically you are having the the return line split into two lines on going still to the tank and the other to the sump again.. THis will slow the flow down for you.

my sump is 30x13x15 which makes it a 25g. the main baffle is 10" high so that makes the pump compartment 10.5x13......ask about anything else if this isnt the problem.

SO did ya add more water to you sump yet.....Honesty looking at the picture i can't see nothing else wron. Unless its me.. Sorry i cant come over to help ya out .... i can start sitting next week so i will hopfully be able to come over and take a look for ya ok....
Ok i have to edit here i just saw something..  Ok you have 2 or 1 overflows in the tank. If you have 2 overflow why do you have it only going to one drain if that is the case. And its been mentioned before. You should have a bigger pipe drain from the 2 split lines to help with the flow. Now if you have 1 line then i think the proble is that you have to maybe lower the 2nd baffle..other then that i'm Stumped

ok.... how bout the space between baffles...
there is something wrong with the drains if your tank overflows can you take pics of the overflow then follow the plumbing down to the sump... more pics are needed to see what your system looks like Dan

The height of the standpipe shouldn't matter unless its higher than the tank I remember you said the tank overflows when you turn on the pump if this is the case then you have a problem with the overflow/ bulkheads... when you turn the pump off after an overflow, does the water level in the tank drop? quickly? slowly? not at all? this is puzzling!
