NT Labs GH – Minerals Up

Low general hardness (GH) can leave pond water unstable, especially after heavy rain or large water changes. NT Labs GH – Minerals Up is formulated to raise and maintain GH levels, helping you create a more stable environment for koi and pond fish.

General hardness refers to dissolved minerals – mainly calcium and magnesium – that support water balance and fish wellbeing.

Why GH Matters

• Supports stable pond water conditions
• Replenishes essential minerals
• Useful after rain dilution or water changes
• Suitable for ornamental ponds and koi systems

If your source water is soft, GH can drop quickly. Keeping it in the right range helps maintain consistency in your pond.

When To Use GH – Minerals Up

• After significant water changes
• Following periods of heavy rainfall
• If water tests show low GH readings
• When maintaining mineral levels in soft water areas

Always test your pond water first so you’re dosing accurately.

How To Apply

• Check current GH using a reliable test kit.
• Calculate dosage based on pond volume and test results.
• Distribute evenly around the pond with good circulation running.

Avoid sudden large adjustments – gradual correction is safer for fish.

Safety Notes

• Use as directed on the product label.
• Do not overdose.
• Store in a cool, dry place away from children and pets.

Maintaining the right mineral balance keeps your pond stable, clear and comfortable for koi.
