It's not just what I need for filtration but most of my fish are not from still waters. They aren't exactly river fish but would prefer current and I'd like to keep them happily spawning as they currently are in the 55g waiting their move. I like the higher gph
and would prefer up near 8times the tanks volume an hour but I doubt I'll make that. I use carbo plus co2
and it has done fine with the 2 biowheel filters. My co2
level isn't way up there but it's enough to keep the plants growing and the algae not growing. Better to keep the tank balanced than to trim it constantly.
Last question is the output and intake connected on the odyssea filter or can I put the intake at one end of the tank and output at the other? It would probably improve filtration to move the water across the whole tank and would give a more unidirectional and natural flow for my fish.
