Hey Guys, I have had my 47 set up for about a year now with about 15 inches of fish, live sand and about 20 lbs of live rock. (yeh I know I am still adding live rock as money permits). By what I usually read my nitrates are not too terrible but I would like to keep them below 10 PPM. Currently 40 PPM. I have a CPR bak pak hob skimmer and a aqua clear hob filter with the foam block, carbon, and bio max. Could I reduce some nitrates by changing to differnt media in this aqua clear? Or should I wait until I get more live rock? And by the way I change 20 gallons of my water once every four weeks.
