    I've got a Nat Geo/Eheim PF20 HOB filter for my 5 gallon Marineland Nook aquarium. It's a filter recommended for a 20 gallon tank hanging on my 5 gallon African Dwarf Frog tank.

    Is it ok to have a bigger filter on a smaller tank? The water sure is clear in my aquarium lol.

    Hi! It should be okay, as long as it doesn't create to much current for frogs. I don't know anything about the frogs.

    Generally you want 5-7 (or even 7-10) times the GPH of your tank. In a frog tank the water usually is lower than the half mark, so honestly a nice 10g filter would usually be accurate. But no, over filtration is not bad.

    As long as your filter doesnt run dry, and the frogs dont mind the current, all good!

    Really as long as you aren't creating a hurricane or tidal wave of some sort inside the tank you should be okay. ;)

    If the current is too strong you can always baffle the filter too.

    In your case, no, it's not bad. I wouldn't buy that filter to begin with, but meh...


    You don't need to over filter your tanks, depending on fish load and plant load if you have plants. What you got for your frogs is fine. You should think about upgrading to a 10 gallon though, they'd appreciate the extra room.

    Why do you not like the filter? I found it to be very nice. It has a flow control and a great filtration system. It's also so quiet you wouldn't even know it's on.

    I detest any filtration products that require the regular purchasing of cartridges. But if it's possible to modify them, then it's all good.
