rowaphos is a very dangerous product to use in an aquarium. it has some very nasty affects to corals. energy has used it in his aquarium and bill has also. but the side affects are not worth it. energy lost alot of corals because of using rowaphos in his system. bill had problems too. i wouldnt use it at all. not woth the chance of wipping the entire tank out with the stuff. there is alot safer ways to get rid of phosphates with out killing the corals. i have used the salphert phosphate eliminator with good sucess. it make phosphates skimmable. you just have to stick with the dosing regiment to eliminate all the phosphates in the rock work.
