## Questions & Answers

**Q: How long does it last you and do I need to buy a syringe too?**
A: A syringe is helpful for filling the test tubes. I would get one that is at lest 20 ml that way you can fill the syringe once and use it to fill all four test tubes.

In the freshwater kit you get 37ml of each test solution except the nitrate one for which you only get 30 ml. The number of drops you use for each test varies, taking one drop as 0.05 ml gives the following approx number of tests:

pH: 245 tests
pH High Range: 148 tests
Ammonia: 92 tests
Nitrite: 148 tests
Nitrate: 60 tests

**Q: Is it single use?? if not how many times can you test??**
A: It is a whole kit with small bottles for each test. You can do probably around 40-60 tests for each of the water parimitars with this kit.

**Q: What is the expire date on this item please**
A: Have just had this product delivered July 2020 with a best before date of December 2024, so good shelf life and only drops needed for each test, weekly use seems to be the recommended

**Q: Can I get new test tubes?**
A: Contact API or your fish pet shop - they should know; the kit has 4 tubes for the 4 tests.
Or do as I did - instead of buying refill of solutions purchase another kit.

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.
