The return side is basically one inch pipe all the way back to the bulkhead fitting then it has 3/4 line loc tubing once inside the tank. The pump i have now is rated 1105gph and it puts a lot of water movement into the tank. Do i need that much? I dont have any corals yet as for i just set the tank up but eventually i would like to have some....like frogspawn, hammer, and other thigns of the such... what do you guys think i need?
ps also...how are the JEBO pumps? i found a used one rated at 1300gph but i dont know hwo loud or well built they are.
You should only run 3 to 5 times your system volume through your sump, so as far as a return pump anything 225 to 375 GPH once you allow for headloss.
The 1260 should work quite well and is 65 watts. If it still a little too much you can use a valve to throttle it back.
Depending on what you plan to keep youll need 30 to 50 times total in tank circulation(2250-3750 GPH), You can use in tank powerheads, wavemaker, closed loop or any combo of these to accomplish this. The proper amount of overall flow is a critical factor to your tanks health, better more than not enough. My system is currently running 40X turnover, and could use a little more.
I dont know about the Jebo pumps but, 1300GPH is too much for both your sump and likely your overflow as well.
