How Many Gph?

  1. GibbyMcGibz Member Member

    Hi! I am slowly but surely getting the supplies I need for my 20 long. I plan on getting a BN pleco and I heard they produce a lot of bioload. Heres the fish I am confident on having so far.
    -1 BN
    -5 Cherry Shrimp
    -1 Mystery Snail

    How many gallons per hour would you recommend for my filter? I plan on having a hang on back one.
    Thanks.

    HOB suggested gph is 8-10 times the tank volume, so 160-200gph on your 20. The Aquaclear 50 is 200gph and I love Aquaclears ;)
