    Default Undergravel Jet (UGJ) Experience anyone?


    0 Not allowed!
    I'm designing a Undergravel Jet system for my 300 gallon tank. The output of the return pump in the sump will be directed into the UGJ system. I have read what I can find online and while I feel that I understand the basic concept well enough, there are some details that I'm not sure about. Like... how many jets should I use? What is the ideal location to position them?

    Given the size of the tank I cannot easily do a lot of trial and error, so I'm trying to do as much intelligent planning as I can before I get started. Anyone have any personal experience running a UGJ system?

    I wish I could help, but I am interested to follow this thread and learn more.

    Would this effect the flow rate from your return pump ?
    If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.

    I imagine if you have too few jets, you'll restrict the flow rate, and each jet will have more force than you want. Too many jets, on the other hand, and each one might be too weak to create the proper lifting effect.
