New Guy Card.....
I have a kit in a box 30 gal
set-up. The hang on back filter that came with it is an Aquatech...seems fine, only a few deaths over the years but I feel like I am ready to get just a little cleaner/clearer environment. I also want to increase my fish density a little.
Any thoughts from more experienced folks on the next grade up (or plus one) for a hang on power filter?
Whisper vs. Aquaclear for example?
Also how about going up one size...40 gal
filter for 30 gal
