Magnesium per liquid 500ml

We recommend Magnesium pro liquid for the rapid increase of the magnesium content in the aquarium water. 1 litre of magnesium per liquid contains 50.000mg magnesium = 1ml magnesium per liquid contains 50mg magnesium With Magnesium pro liquid only the magnesium actually consumed should be replaced. i.e. First the actual magnesium value in the aquarium must be determined by measuring. The missing quantity should be added over the course of the day ! After a few days you will know the consumption of magnesium in your aquarium and you can add the daily consumption via a dosing pump. Complicated ? Not really.
