20g Frag tank

[lolgranny]

What would u suggest for filtering a 20gallon frag tank. All i have ATM is a wet dry which i used for my 75gallon, so i assume that is OD. What would be ideal? a smaller wet dry? A hang on the back filter? I havent worked with smaller tanks so im unsure...

why not a small overflow, into a refuge which would have some sort of mud to restore nutrients and minerals that your frags would use up. Put some chaet in the refuge and a bit of rubble to help with a good bacteria base. The overflow would cut down on water flow that couldn't be adjusted to give you more room for power heads and flow that you can adjust and direct as needed.
