I have no clue what you are really asking...Are you asking if you can use this system on a reef tank? Normally these setups are used with FOWLR setups and frowned upon for reefs. This is due to the bioballs creating excess nitrates if they aren't maintained properly, I'd say cleaning them at minimum monthly. We usually stick with refugium setups in reef tanks to export nurtients instead. Is it possible to use on a reef tank though? Yes, but I wouldn't try it myself.
