As far as reef controllers go the Apex and Reefkeeper are the two big ones, opted for an Apex Jr myself. They can both control ato's, lights, pumps, skimmers, heaters, the list goes on. By water parameters I'm assuming you mean test kits. Stay away from API as there not that great but there's salifert which are good, Hannah checkers if you wanna go more high end, and I'm sure others can suggest more. Tunze ATO's seem to be the most reliable bit theres the jbj which many seem to like too. Lighting can get very expensive depending what you want. If your going led's you can get cheap Chinese black boxes, reef breeders makes a couple good ones at a mid level price, all the way up to the ecotech radions or ghl mitras which come with a high price tag. You also have the option of t-5's or metal halide. Replacing bulbs can get rather expensive and metal halide generate a lot of heat. It all comes down to personal preference and if your trying to keep mostly soft, lps, or light loving sps. If you could tell us the intentions for this tank it can help narrow things down a little better.
