anyone have any experience using the zeomag? i put some in my deltec reactor and now my mag is 1680. i used less than what the instructions said, which is 10% of the total media in the reactor. will running a high mag reading the tank harm anything?
yes. A few coral don't like high mag and will RTN or show signs of stress/die. On a good note, high mag is used to treat bryopsis =0) Mag works indirectly with calcium and will change the way its broken down/used in the tank.
