I am starting my journey into the world of SPS and i was wondering if dosing anything is necassary or if nice clean water is going to do the trick? I dont dose my tank as of now and everything is growing and doing well. I keep Softies and LPS at this time but would like some of those colored sticks aswell. My lighting is Dual 250watt 12k reeflux bulbs with T-5 actinics and this is in a standard 90. Thanks for the help in advance.
