hi again!! just want to share my opinion on the new range of red sea supplements. im thrilled!! been doing alot of experimenting in the shop on our various display tanks and tried the coral growth program, and the coral color program. the results are unreal! ive been testing daily and dosing accordingly, and have not seen such stunning colors in a sysrem before. the no3 po4- has worked brilliantly, dropped the phosphates and nitrates so low can hardly get a reading when i test, so feeding my scaled friends extra now they love me more lol. value for money, and ease of use the new range i think is one of the best you can get. worth trying, come in and see our red sea max displays, and the growth of the corals in the main show tank.
