I have been dosing magnesium. I am currently at 1350. I dosed 20 ml in my 60 gallon tank and my turbo just dropped and died. My nassarious is now not looking good. I use the sailfert test kits. I have been dosing under the recommended amounts. I wanted to get my magnesium up to 1400. From what I read, this level should bother them but it seems to be killing them
