The thing I need to know is if I do add second filter to my 20 what size should I get ?
And for my 26 gallon I want to way over filter that also but id rather just use 1 in that just over rated size. And what should in get aquaclear it C series?
For the 26 the c3 would be perfect. I had a c3 on my 20 long set on the lowest setting and it was perfect. On a 26 bow the flow could be adjusted to need your needs, its a really great filter I think a c4 even on the lowest setting might blow some things around. For the 20 since you already have a good filter just get the fluval ac30 which is what they recommend.
