Does it job
I believe it tests right. Ofcourse only got this to test the water so nothing to compare. It comes with a very handy plastic 5ml test tube that got a lid that is attached. Prefer using this one.

Easy to use test kit
Use api test kits all the time easy to read results. Used on both my marine and freshwater tanks with no problems.

API phosphate tester
Good value when you consider the number of tests you can carry out. However, not great if you need to be super accurate in the lower end of the phosphate scale as may do with saltwater tanks.

Good Test to have in reserve.
I suspected high phosphate was the cause of my sudden growth in velvet algae. This test proved it. But moreso, that our tap water which I was using for water changes was also high in phosphate- so needed to use a phosphate remover. Test has come in very useful.

Perfect like all the products from API

useless
These are completely useless and would warn anyone against using them. These almost always show at least a 1 phosphate reading even if no phosphates exist I tested this against pure ro water, distilled water and de-ionised water, all of which read correctly with other tests. Regardless of the water type the test always shows the same meaning the test is completely useless for intended purpose

Planted Aquarium -- Water Testing
This is perfect for hobbyist like me that enjoy discreet nutrient supplementation. Makes it fun watching over time the depletion of phosphate. I then experiment with different dosaging of phosphate based not only on quantity added but also seeing what is measured in the water The results of this product using drops of reagents seems more reliable than another product that I purchased that works by inserting of a strip in a test tube filled with the sample under test. However using a competitor strip test product is more convenient. I use the competition brand strip test as a quick way to determine whether phosphate is measurable. Then I use this API drop test if I want to investigate the ppm further

Pod test kit
If you have a pond, you need API products. They are the only ones my husband uses.
