I was at FFM and talking with the Tropic Marin scientist regarding the carbon dosing in a mature reef tank. Ive never done carbon dosing but many have sung the praises of the carbon dosing method over the years. He peaked my interest with its ease and commitment to how exceptional the product is...I guess hes a good salesman too. Has anyone used this product before? I know you need to get the P04 levels in the tank into the optimum range before starting the method, so Ill have to raise my P04 from ,03 to .08 but that shouldn't be too hard with their NP+ product he so gallantly provided. Are their potential side effects or concerns with this method which could result in nuking my corals (my major concern)? any experiences or advice would be appreciated. TY.
