“As an ammonia test I think it's great although when unpacking the tester the protective film on top it's glued so well that by pulling it you risk damaging the test itself and at time it does happen that you peel some of the middle part off, not sure if this will impact on the performance of the test. But overall I'm happy with it and the test it's working for a year”
“Easy to use but the quality of the indicator disc can vary as some are perfectly smooth and others have a ripple in them which makes it slightly difficult to read. Correlates to what the water tests are saying so appears to work, although I've not seen mine change colour because of no ammonia in the tank water.”
