Colombo GH+ restores the total hardness to your pond water.

A correct total hardness (GH) is a prerequisite for clear water with healthy plants and fish. GH stands for total hardness, being the total quantity of dissolved minerals in the pond.

Your plants and fish need these minerals for their growth and health.

The GH Value should be between 8 and 12 DH. When the optimal GH value is reached, stabilise the values with Colombo Balantex.

Colombo GH+ Dosage:

15ml per 200 litre of pond water increases the GH with 2 DH.

First dilute the required amount in a bucket or watering can with lukewarm water. Never pour onto plants.

Test your water quality monthly and correct if required.
