Make a 50-75 gallon sump and turn over 1200 GPH.
A sump is a much better choice that an FX5, IMO they are overrated, I had one for a while and don't get me wrong, they are great filters for the money but a sump completely outperforms them. A sump is more convenient to clean, allows storage space for heaters, C02 etc. and can be filled with way more biomedia than a canister. Just my 2c worth
