i decided to invest in the dual chamber bulk reef supply GFO and Carbon reactor...[url=http://www.bulkreefsupply.com/store/products/carbon-and-gfo/media-reactors-filter-bags/dual-brs-gfo-and-carbon-reactor.html]Dual BRS GFO and Carbon Reactor - English[/url] it arrived two days ago and i set it up yesterday... im using the regular granular ferric oxide [even though i wanted the high capacity gfo but it was out of stock] and the ROX 0.8 high performance carbon. im actually using less carbon than gfo as instructed by the site but my question is regarding tumbling.... i was under the impression that the carbon should remain still and packed into the chamber however i can not set my flow rate low enough to prevent the carbon from tumbling more than the GFO. it ran clean after about a gallon so even tumbling like that it doesnt seem to release dust... when i first packed it i tried to keep the carbon sandwiched between the foam pads but the water flow pushed the top one off.. should i try the foam pad again to pack it down? or does it even matter hat its tumbling? here are the reactants im using...
