Before you can even think of playing around with the magnesium concentrations, a test kit that will enable magnesium concentrations of the water to be measured is required. It is bit of a fruitless task to be adding something when the actual concentration is not known to start with. The kits are relatively easy to use, using the titration/colour change technique to determine the concentration that calcium test kits use. Once a test kit has been obtained, then there are basically four techniques that can be used to add magnesium. Water changes Dolomite in Calcium Reactor Commercial Additives D.I.Y. Additive The dosing rate is simply: to increase the magnesium concentration by 100 ppm, add 1 gram of Epsom Salt per litre of water. As with anything change with the water parameters, take it slowly, and any sensitive corals will soon show effects when things are altered too fast for them. The following is the system that can be use to add magnesium using Epsom Salt. Calculate the total system volume, including tank, sump, and other water containing equipment. Don't forget that rock and sand takes up water volume and that tanks are not filled right to the top. By a rough approximation, it can be assume that all the sulphur present is found as sulphate, SO42-. Note that both the magnesium and sulphate exist in comparative concentrations, around 1,000 ppm. Therefore for a given increase in the magnesium concentration achieved by using Epsom Salt, a comparative increase in the sulphate concentration will also occur. In contrast if the magnesium additive magnesium chloride (MgCl2) is used the effect will be smaller. This results from the factor of fifteen higher concentration of chloride over that of magnesium. Now for as how this applies to our reef aquariums, I think that the increase in sulphate concentrations should not cause any problems. Low magnesium levels cause more, and the amount of Epsom Salt required to maintain the magnesium concentrations once they are up to the correct level is small. But having said that, it is better to strive for the conditions that our system inhabitants are adapted to and have evolved in. If a source of magnesium chloride that is not expensive and can be afforded can be found then go ahead and use it. Although because of the ease of access, price and simplicity of use, Epsom Salt is a great place to start, or even end with, maintaining magnesium concentrations. |
