After lots of searching I think I've come across just about all of my filter options:
Canister ( thnx Ian)- This would be by far the easiest but in the long run I think it would fall short of my needs.
Sump- I like the idea of more water volume and I'll be able to hide an acrylic stand pipe behind the root pretty easily. The only "problem" is the sump itself. This is a small house and floor space is at a premium. So, I'm going to man-up and drill through my maple floors (I know I can convince myself to do this) and set up a 29 gal. tank in the basement.
From what I've seen -FW protien skimmers, bio-balls, charcoal and filters. refugiums, and algae skimmers- I like the latter the best. I also like the idea of a refugium and thought the sump would be set up in this order- intake from tank flowing over scrubbber, baffle, refugium, baffle (in this area I would make space for heaters or CO2 diffusers if needed), and finally outflow back to tank. Do I need any more? Mechanical filtration? Any input here would be appreciated and give me the courage to drill through my floors- they already have patches- I know I can do it.
Thanks!
