Hydra Parameter Control System

Controls GH and KH with a simple and predictable solution.

Choose Parameter Control if you measure GH and/or KH below the desired value and accurate to remineralize or stabilize the water.

includes Hydra GH+ + Hydra KH+ And it was designed for aquariums with osmosis water, very soft water or parameters that need controlled correction.

It's for you if...

• use reverse osmosis water
• Mediste GH or KH lows
• need to increase overall hardness and/or buffer power
• Do you want to keep the adjustments separate and measurable?

what includes

✓ gh+ - Increases overall hardness by providing calcium and magnesium

✓ kh+ — Increases carbonated hardness and buffering power

important before buying

This is not a product of universal use. Measures first GH and KH and sets the target value according to the fauna and flora of your aquarium. Do not adjust parameters by routine no need to measure.

How to use — Reference for 100 L

GH+: about 10 ml to increase approximately 1 °DGH.

kh+: about 10 ml to increase approximately 1 °DKH.

It makes gradual corrections, measures again and avoids sudden changes.

expected result

parameters more stable and suitable for fauna and plants, with greater control over the mineralization of water.
