Building a 8x4x2 plywood tank and want to know what filtration I should use I don't want to use a dump and also what amount of water I would need to change weekly it roughly works out to 1800 l
I was gona suggest this same setup. 2 fx5s by Fluvalyou don't need a 200g sump for a 500g tank.Alot of your filtration is going to depend on what your stock is. I filter my 450 gallon tank with two FX5s and a 40g sump, and have no issues whatsoever.
