ro water is i think the purest water on the planet! hook it up to ur sink and let the ro filter do all the work. their well worth the money if u plan on keepin corals. at first i didnt have one,now i do u can see the difference!. no more algae and the corals are bigger and more colorful. the best 100 bucks i ever spent! look on auction sites. people buy in bulk and make there own. then sell them on the auction. helps keep their prices low.
