NT Labs PondLab 200 Test Kit
Successful fish keeping lies in the maintenance of good water quality. The pH, Ammonia and Nitrite levels in a pond should be checked regularly, usually weekly in a new pond and fortnightly in an established, mature pond, although more regular testing may be required in some circumstances. Poor water chemistry will cause stress to your fish which in turn decreases their immunity making them more susceptible to pathogenic infections and poor health.
See the back of the box for pictorial instructions on how to use the test kit. Colour coded stickers are provided to label both the test tubes and their lids to eliminate contamination and remove the risk of false readings.
