well, a little story first, i had a pretty tank with xenia and many other beautiful corals, until one day when i had swine i realized "my calcium levels are a little low, lets top it off with this gallon jug of kalkwasser" so right now all i have is live rock, my clown a damsel fish and my C.U.C., i hvae pc lighting 108 watts, but i believe this should be fine since my tank is about a foot tall so it will always be close to the light, also what would a good size haddoni cost? im looking for the size range of 5-8 inches
