When I first got interested in aquaculture I use a very similar product by another well known manufacturer. I found their small kit to be very good and so eventually graduated to their "Master" test kit. I found the results from some of these tests to be very difficult to interpret as the colours produced by the reagents were often too similar to be able to determine an accurate reading and so, when I needed a buy a replacement kit, thought I would try APIs offering. The bottles actually have the number of drops required printed on them so the dosage doesn't have to be looked up in a booklet every time. The bottles are also designed with a unique (at least I've never seen this before) child proof cap where a small locking collar has to be held firm with a thumb before the cap will unscrew. One of the better child-proof designs in that adults can actually open them very easily! Unlike other brands where only a loose fitting test tube cap is provided, the API test tube caps are a secure fit - essential when shaking a corrosive or irritant test solution for up to a minute. Just as important, the test tubes are easy to rinse without leaving the residue on the glass that I have found with other test kits. The tests either provide instant results or after a 5 minute "developing" period. This means that tests are easier and quicker to undertake compared with other manufacturer's kits where the waiting time for tests varies from instant, to 2, 5 or 20 minutes. The resulting colour changes are very easy to compare against the test chart provided. All in all, an easy to use and well designed kit at a competitive price.
