Magnesium buffers

Blended magnesium buffer in powder or concentrated liquid

Powdered additives

Magnesium buffer powder supplement.

Mixing, storage and dosing instructions

Mix 100g with 170ml of RO water to produce a liquid buffer solution that can be added to a reef aquarium to raise or maintain the magnesium level. Add powder to water slowly and mix or shake to dissolve. DO NOT add powder directly to the aquarium as the initial reaction generates heat. The dissolved liquid solution is easy to dose by hand or with automatic pumps. If the liquid is stored open to the air evaporation will occur, increasing the concentration and can allow powder to settle out of solution. If this occurs replace the evaporate losses with RO and remix. To avoid this happening, only produce enough solution for 4 weeks of use at a time. 1kg makes 1.7 litres of solution.

17ml solution/100 litres raises magnesium by 13.4ppm Mg
1.3ml solution/100 litres raises magnesium by 1ppm Mg
Do not raise levels by more than 10ppm Mg per day in an established reef aquarium. Add in a high flow area such as a weir or sump. If calcium levels also need adjusting then adjust the magnesium first.

Storage and dosing instructions

The liquid solution is easy to dose by hand or with automatic pumps and can be stored indefinitely between 10°C and 30°C in a closed container. If the liquid is stored open to the air then evaporation will occur, increasing the concentration which can allow powder to settle out of solution. If this occurs replace the evaporated losses with RO and remix by stirring or shaking.
