Colombo Nitrate Pond Test Kit
Colombo Nitrate Pond Test Kit (NO3), is produced from the breakdown of nitrite in the filter.
Nitrate is relatively harmless to freshwater fish, but its presence can indicate a deterioration in the aquarium environment, and high nitrate will encourage algal growth.
The only way to know what the nitrate level is, is by testing it with a Nitrate test kit.
Colombo Nitrate Pond Test Kit contains 40 tests.

Koi Medic Digital Salinity
The Koi Medic Digital Salinity Tester is the ideal way to test the salinity levels in your Koi pond. This technically advanced device gives fast and accurate results every time. It is very easy to use, simply dip the sensor into the water and read the result.
Using the Salinity Tester each time you add salt to the water will ensure that the water levels have just the right level of salt. It’s important to ensure that the salinity levels are optimised to ensure good fish health and to eliminate parasites in the water.
The Tester uses 4 x 1.5v batteries and has over 150 hours of life. It conserves energy too, thanks to an automatic shut off after 15 minutes.
Please note:
It is strongly advised that you do not add salt directly into the water in large amounts. This may burn the koi. Also check the salinity levels of the water regularly as it can be affected by wet or dry weather conditions.
