Update... Going to work on getting my PVC pipe and I'm going to measure all the necessary measurements. Buying my sump this weekend. going with a glass sump.

Two questions:

should I wait on placement for my skimmer when I get my sump or is it a better idea to buy the skimmer and start on measurements?

How much Gph should I have for my return pump? Might go with 1" PVC pipe.

Your return cannot exceed the overflow capacity or your sump will be pumped dry. A 1" drain should provide about 600 gph depending on your DIY syphon. So if your return is more than that (after headloss) you will need to use a valve to reduce it a bit.

My syphon will look like a HOB type bc I can't drill my tank. I will put a check valve and a couple of valves to reduce the water levels.
Kind of like this guy...

Question on the overflow box... What does it do necessarily? Is it just syphoning the water from the aquarium to the sump? The only reason why i am questioning an overflow box is because wouldn't a canister filter be useful in a sense? For example... If I kept the intake bar in my tank where it's at and I placed the spray bar in the sump and placed a return pump inside my sump to the tank. Wouldn't it be doing the same thing? Granted I'd be using the canister filter as extra filtration or just as a water circulator. Does that make sense? I mean I'm utilizing the things I currently have rather then making more of a mess. Is this possible or does it sound like a headache ?

Sorry for the bad drawing but can you see what I'm saying? Or if you need water to just be skimmed off the top I could just reverse the tubing of the spray bar in tube. What are you thoughts????

If you would do that then you would have to match the two pumps EXACTLY or else one will be working harder then the other causing one of your tanks to flood. The reason we let gravity take care of the overflow is because it will be able take more water if needed as the pump returns the water to the DT. Do you get what I'm saying?

Ahhh I get it. The Gph on both the return and overflow has to be the same... I guess that makes sense. In order for me to have the same Gph on the return would be madness. Haha.. Ok I give in to the overflow box. Lol

In addition to what Mrc said, if you have a power outage in that configuration, you'd actually creae a siphon through the canister filter until the siphon broke at the canister filter intake, likely overflowing your sump.

As far as the Eshopps v. CPR, I've heard good things about both. I've used one that looks a lot like the Eshopps version on my 37 for years with no issues. I beleive you have to use some kind of pump on the CPR version like an aualifter or powerhead with a venturi to maintain siphon.

I am using a CPR and so is my roomate. They work great! You will want to get a aqua lifter though to keep the air out of it so it doesnt break suction. I have the CP90, I run a MAG drive 7 pump on mine and it handles it running wide open and could take more.


The overflow you will want...
