The TOM filter looks like it'd be perfect. Thanks. Any suggestions on lights also? Looking for some type of clip-on. I was looking at the Finnex CL26SL, but I'm really not sure if thats a good light or not...TOM internal filters are great. 45gph and very small and compact. If the tank is tall enough an HOB would do. A marinleand mini biowheel is a good choice.
I have this filter on my 3.5 gallon. It's perfect, but on a 7 gallon, I would go with something a little bigger. Maybe the 511 ZooMed.I personally don't like internal filters. On a 7g cube I'd recommend an HOB or canister filter.
Also a ZooMed 501 on the well priced canister side.
I hope this isn't considered hijacking, but would a ZooMed 501 be considered sufficient for a 5 gal tank? And what does everyone put in their's instead of carbon? Sintered glass? More ceramic "macaroni"?
