    As some of you know my 40 gal. Breeder project is almost done [​IMG] I bought Return Pump as last piece to finish… I decided to buy new version of Jebao DCT 4000 which max flow is little over 1000 gal/hour. But Im confused now. Either pump is defective or…. no idea. Pump has 10 speeds but on full power it is still little flow in the tank. I don't know whats going on. I have a 3/4 PVC return pipe split with tee and then pipes go to two corners. Nothing fancy just regular plumbing. I will try to return it and get 6000. Will see if I can do it. So Im back on market for Return Pump. Any idea what I did wrong? thanks.

    That last pic shows how small inside diameter is. I can't believe it. Looks like less then 1/2". I went to Home Depot and bought some PVC and change that part with inside almost 3/4". It did help a lot but still not what I would like [​IMG]

    There may be nothing wrong with it. I assume you have head height, etc.
    I would think you'd need at least one power head in the DT also for flow.
    It's a rare thing when someone relieds solely on the RP for DT flow.

    Good luck

    TEES AND ELBOWS WILL DRASTICALLY EFFECT FLOW AS WELL.

    I thought that it will have more flow even after head loss and tees and elbows. I understand that I need power head or two also. I should buy 6000 version. Thanks.

    Time it to see how long it takes to fill a 5 gallon tub at the same height.

    I use the DC12000 in my 90 gal tank. I run 1 inch pvc return line and off that return line I have my recirc skimmer plumbed in. They are pretty good pumps for the money. This is my second one I bought. My first one quite after a year of continous service without even cleaning the thing. And even when it quit, I don't think it's the pump that died, but the controller that went on it. Just don't forget the head pressure on a larger diameter line will increase a bit more because of the weight of the water. I have my headpressure at about 5 1/2 feet and it runs at about 1200gph 3/4 speed.

    I have a DC6000 on my 66 gallon tank and the most I can do with it is about 1/2 speed. otherwise my overflow is too noisy. they are good pumps, but i woudl check yours. something doesnt sound right.

    I see a lot of plumbing restrictions; the section of clear vinyl tubing being one of the biggest. That reduces cross-section quite a bit.

    Can we see the rest of the plumbing? If you have a check valve in there, that's another sizable restriction.
