although i use it in freshwater plant tanks with alot of success, i agree,never ever on the saltwater unfortunately, i strategically put my first reef, a 29 gallon, right under the brightest window in the house thinking i would approach it like a freshwater planted tank, it was an allout disaster within a few months,after moving it to the other side of the room its like night and day. _________ Believe it comrade!  |
