Setting up sump help please

[Sflynn313]

I'm setting up a sump for my 150 gallon tank can I have the water overflow into the sump pump, then into uv sterilizer back into the main tank?

Not clear on your question. It comes out of the display through your overflow into the sump and then you have your return pump pumping the water back up through the uv sterilizer into the display? If so that is one way of plumbing it. That's how I have mine, but there are other ways.

Yes that is how I want to do it thank you

Make sure you don't exceed the recommended flow rate of the UV sterilizer. Also don't forget to use unions on each side of the sterilizer so you can remove it for any maintenance.

what size return pumps are you going to be using on the 150 gal? I am in the middle of a 150 gal build right now. I have tap water in the tank to check for leaks and function. the tank has 2 durso overflows on the back (not corners). I called aqueon and they say the overflows are rated at 600 gph. I have 2 mag 9's for the return and it is just noisy. I have tried putting the rigid tubing down the durso's, I have tried making stockman returns and they are just as loud. The only thing I can think of doing is going with smaller pumps. The mags are rated at 680 gph at 5 feet, which is the height of the return line outlet in the display tank. One of the returns run through a UV sterilizer, and I can physically feel the difference between that line and the one that is going straight into the tank, so it's got to be at least a third less. the 40 watt Smart Uv Lite I am using gives 2 ratings, 98 gph to 164 gph for Protozoa, and 589 gph to 983 gph for Algae and Bacteria. I was using it for the latter but if I use a mag 5 the gph with a 5 foot head would be 325, which is somewhere in the middle of the 2 ratings. how would that effect what I am doing? would it kill anything that passes through it, like cope pods and ampipods? anyway, the question is how much flow do you usually shoot for on the return pumps? I plan on using 3 vortex mp40's for the powerheads, so overall total flow is not really my concern. everybody keeps giving me the same formula of 10 times the capacity of the display, for total flow. Which doesn't help with my question of "what is the minimal and what is the average return pump size one should get for a 150 gal display???? can I cut it to 600 or 700 total? would that hurt or diminish the overall system in anyway if I make up for the overall flow with my power head????

thanks for any light you can shed on this...
