Im currently running 2 fx5's and a Eshopps 300 wet/dry filter on my 500 gal. ray tank, I have 2 overflows which both run to my wet/dry filter. So my ? is should I run a wet/dry or sump to each overflow, maybe go with one very large wet/dry or sump, or go with a large pressurized pond filter. I have young rays at the moment but want to go with something that is going to plenty for when they mature, i dont want to have to upgrade again in the future. Eventually I will Only have 2-3 adults in the 500, thanks for the help.
