The reef style tanks are expensive and you could probably do ok without all the wet/dry filters. Underground filters are ok but must be cleaned to stay effective. and additional filter or 2 would add a margin of safety. a hang over the back and/or a cannister would be good. Good luck.

thanks james....agreed!

Hi
Think if I were to do it particularly for Discus Instead of
the w/d filter would spend the money on a auto or semi water change , along with a RO system.. if ornamental you could go heavily planted or for breeding bare bottom .
You'd always have ideal water conditions as well as save you a ton of work gary
