DescriptionTNC GH Boost contains Calcium and Magnesium salts. Added to your tank it will increase the water hardness and the levels of these two essential nutrients - both of which are essential for healthy plants.
GH stands for General Hardness - sometimes referred to as permanent hardness. It is the measure of salts dissolved in the water supply and is measured in degrees (°GH or dGH)
Although both Calcium and Magnesium can be found in most domestic water supplies, the quantities can vary depending on where you live. If water is described as 'soft' there may be very little, if any, of either. This can result in plants showing signs of Calcium and / or Magnesium deficiency.
If RO water, rain water or soft water from the tap is used in the aquarium then Calcium and Magnesium should be added. For most plants a GH value of 6 is about right.
To check the hardness of your water, you could use a test kit or you could check on your water suppliers web site if you are using tap water
1 tspn of TNC GH Boost will increase the hardness of 140 ltr of water by 1 dGH
(If you are using TNC GH Boost as a supplement to an EI dosing system, add straight after your weekly water change. You will not normally need to add any additional Magnesium Sulphate)
CaO 17.9% (Ca 12.8%) MgO 7% (Mg 4.2%)
