Got Live rock from MArco Rocks (great looking rock which I love!)and have been curing in my empty tank for three weeks. HAve had two powerheads going for good water movement and the protein skimmer going as well. Been doing 20% water changes one to two times a week. PRoblem is I sill have a low level of Nitrite and ammonia whne I test. Am I being impatiant thinking should be cycled sooner? Friend said I tun o the MAgnumn 350 filter and biowheel to help promote good bacteria and will lower the Nitrite and Ammonia but have heard other wise as well. Any thoughts?
