Does anybody use purigen by Seachem in there systems , if so is it a good nitrate reducer, and does it have to be run through a reactor? I have had a nitrate problem in my 55 since I set the tank up in Feb. I have a ETSS skimmer that's rated for 250 gal and I've cut back my feedings to every other day. I have a small yellow tang small juvie lionfish a couple black swallowtail damsels and two small maroon clowns I keep the skimmer free from detritus and don't use filter sock unless I'm blowing off the rocks. I've been reading the 80+ page thread on remote deep sand bed bucket in RC so that will be my next venture if I cant find a good filter media besides Chemipure elite which I use now and love I never have Po4 I just cant get my nitrates below 40-80. Please if anyone knows a good filter media that doesn't require a reactor its much appreciated. Happy Reefing !:frusty:
