Sump media question
 

I have recently added Rowaphos to my filter system (sump). I also have carbon in there too. Is this ok? Is there an order in which they should be placed? Right now i have Rowaphos on the top then carbon. Should it be the other way around? All my media is in the last section before the return pump. Any advise would be greatly appreciated.

Anyone???

that is just fine but i would put it in the first section though
if you want to put it to better use i would get a aqua clear filter
and throw it on your sump and put the carbon and rowpos in it its cheaper than buying a reactor
