🔴 KH PLUS – Increases Carbonate Hardness

COLOMBO KH Plus increases KH (carbonate hardness). Adequate KH helps buffer aquarium water against sudden changes in pH, contributing to more stable water conditions.

Main purpose:

✓ Increases KH / carbonate hardness

✓ Helps stabilise aquarium pH

✓ Supports more consistent water parameters

✓ Useful when aquarium KH is below the desired level

What is KH?

KH measures the carbonate/bicarbonate buffering capacity of the water. When KH is too low, aquarium pH can be less stable.

COLOMBO GH Plus is designed to increase GH (general hardness) by increasing salts and minerals in aquarium water.

Main purpose:

✓ Increases GH / general hardness

✓ Adds minerals and salts to aquarium water

✓ Helps achieve appropriate mineral hardness

✓ Useful for aquariums where GH is below the desired level

What is GH?

GH indicates the concentration of dissolved minerals associated with water hardness. Different fish species have different preferred GH ranges, so test your aquarium water before adjusting it.
