Colombo GH Plus

A correct General Hardness (GH) is essential for clear water. GH is a measurement for the total amount of dissolved minerals in the water; these minerals mainly consist of Calcium. These minerals are essential for the well being of your fish and plants.

Colombo GH+ increases the concentration of salts and minerals in the water. These minerals and salts are necessary for healthy plants and fish. The GH value should be in the range of 3-12DH. You should not increase the hardness faster than 2DH per day. 

Use: Add 1ml GH+ for every 5 litres of water to increase the GH by 2DH. The cap holds 10ml. Shake well before use.
