Ok. Has anyone tried raising their magnesium levels to 1650 to deal with hair algae issues? I got a frag from a fellow reefer and a pretty invasive HA got a good foot hold on my tank and my tangs aren't touching it. I've heard and read about this method to take care of many forms of hair algae. Are there any negative side effects to doing this for an extended period of time until the HA is gone ? I know i need to raise it slowly. Testing each morning and night to see the effects of dosing does on the tank. Just curious if anyone has tips or tricks. Or maybe a better idea. Thanks
