## Features

- 【SAFELY INCREASES GENERAL HARDNESS】: NT Labs GH Minerals Up safely increases the GH providing an optimal habitat for your fish and other pond life.
- 【BOOSTS GH LEVELS IN YOUR POND】: General hardness minerals such as calcium and magnesium are essential for aquatic biological functions. Such minerals are used in fish growth, metabolism and other physiological functions. General hardness minerals can decrease over time due to influx of rainwater, soft tap water and biological processes using these minerals.
- 【EASY TO USE】: To work out the required dosage for your pond, simply calculate the volume of your pond in litres (length x width x depth (in cm)/1000) or alternatively, use our Online Dosage Calculator. Dissolve the powder in a bucket of pond water before adding to the pond.
- 【USE IN CONJUNCTION WITH NT LABS TEST KITS】: Use NT Labs Hardness Test Kit to measure the GH of the pond water. Always keep the GH above 8 dGH for optimal water quality. GH Minerals Up can also be used to provide additional general hardness where tap water is naturally low in hardness minerals.
- 【 SUITABLE FOR ALL POND KEEPERS 】: The ease of use of Koi Care GH Minerals Up means it is perfect for use by beginners and seasoned pond keepers alike.

## Questions & Answers

**Q: Can you use with pump feed ponds**
A: Yes. No probs. As far as i understand its also benificial to your filter . Used it for a couple of years now along with kh up. And koi clay. All good .

**Q: What’s is a ratio mg to ca ?**
A: No idea, all I do know if the water hardeness is well below the 8dh level the pond quality will function less,due to a depletion of minerals in the water, which in turn can affect the fish plus the PH level, best contact NT labs for more information, that's why I check mine on a regular basis along with other chemical tests
