I am setting up a 75g discus tank soon and was wondering if 2 SunSun302 filters would be enough filtration/flow for a planted discus tank? I know their flow rates aren't exactly what they are advertised (~260gph) so that's why I'm a little skeptical. I plan on replacing the spray bars with 2 of these http://www.amazon.com/Hagen-A20001-F.../dp/B0002Z7UFG
- also I want to put a 200W Hydor ETH on both filters and add an inline GLA diffuser to one. I'm sure my inline additives will reduce circulation even more so what are yours thoughts/experiences? Should I just go the fluval route or add a nano power head?
