Hello everyone,
I just saw a picture of someone who had their overflow filled with (what I assume are) bio balls. the overflow still flowed down to a sump.
Now on to my question, is this something that is worth doing? also what would be the pro's and con's of adding this additional biological filtration to my tank?
thanks!
