    Don't dose more mg, let it come down on its own as your tank uses it.

    @mitchel Purple Up is the problem as it also contains Magnesium. so besides the Mg that you add with your water changes you also add more with this product. i found that magnesium is one of the elements that take the longest to be consumed by the tank and thats why its so difficult to get the levels down. stop using Purple Up as its pretty useless supplement IMO that contains very little amounts of trace elements and do a large water change.

    Just for interest sake, test the magnesium levels on freshly made salt water, before you add it too the tank.
