⚙️ HYDRA PARATER CONTROL SYSTEM

Technical assistance for GH and KH control.

System for precise adjustment of general hardness (GH) and carbonate hardness (KH) in aquariums.

Who is it for?

✔ Aquariums with reverse osmosis water
✔ Aquariums that lose parameter stability
✔ Fauna and flora sensitive to variations in GH/KH
✔ Advanced technical models

Includes

• GH+
• KH+

What it does — benefits

✔ GH+ — increases overall hardness (each 10 ml increases ~1 °dGH)
✔ KH+ — increases carbonate hardness (each 10 ml increases ~1 °dKH)
✔ Helps stabilize pH buffer
✔ Facilitates remineralization in reverse osmosis water.
📌 Information based on the formulation of Hydra products; ideal for fine control in planted aquariums and sensitive fauna.

How to use (100 L)

GH+
• 10 ml → +1 °dGH

KH+
• 10 ml → +1 °dKH

Adjust according to GH/KH test readings and the aquarium's needs.

Estimated duration

Depending on the original water and hardness goals, these solutions can be used as needed (usually weekly during adjustments).

Expected result

👉 Stabilized GH/KH control
👉 Ideal water for demanding wildlife
👉 Better support for plant growth and biological processes
