Well I tested my Mg and was suprized at the results. I have not added anything to the aquarium to increase the Mg so I figured I would test it and then add some if needed. I do not need to add any because the Mg is about 3000ppm!!! Twice the maximum amount the aquarium should have. So now the only way I can think to lower my Mg is to do water changes or add some mangroves. At the time of the Mg test the Alk was about 3.43ppm and the Ca was about 450ppm. Any other ideas on how to lower the Mg.
