I have a 180gallon system with a wet/dry and coralife 220 protein skimmer. This is my first saltwater/reef tank. I started out with my sand bed adding about 240 Lbs of fine Bermuda sand (forget the brand name, maybe araglive or something) and 5 Lbs of Live sand. When that settled I added my 160 LBs of live rock. I have had my lighting running 10 hours a day and everything else running as well. Dont know the exact size of my wet/dry filter but it is overkill (big enough for 300g tank. Im 2 1/2 weeks in to cycling the tank and have a full on diatom bloom going on. My tank just started running hot today at 86 degrees but i added fans and took off 1 glass lid for cooling. Ive been testing the water the past few days and im at 0 Ammonia, 0 Nitrites, 20 Nitrates, 500 calcium, 11 or 196.9 alkalinity. I wanted some input from experience people whether they think the cycle is finished and it is safe to start with a cleaning crew? I know every1 stresses patience but i would like to get them in there to take away some of the mess. And im just excited to get it going. Or should i just wait it off?
