I am ready to make the jump to saltwater after several years of keeping african cichlids. I have 4 tanks, a 75g, 55g, 30g and a 20g. I am going to use the 75 for the conversion. Equipment already have is as follows, 260 watt power compact and a 120 watt strip, fluval fx5 and a fluval 405, 2-250 watt heaters, 2 aquaclear 70 powerheads. I am going to go with a fish only with live rock tank. Do I need anything else to get up and running besides the salt and testing kits? I want to cycle the tank with damsels and live rock, is this a good idea? or should I just go with the fish until it cycles? all info everyone can give will be greatly appreciated as I am a newbie to saltwater.
