APIPhosphate PO4 Freshwater & Saltwater Aquarium Test Kit 150 Count

This is about the easiest phosphate test kit I have ever used, and the company that makes them has really great customer service. One of the test tubes arrived broken (not a huge deal, there are two in the package) so I reached out to the customer service email to see if they had extras available for purchase. They took a while to get back to me, but were very apologetic about the wait and went above and beyond to make it right. They sent me a brand new test kit, and a hand-written note expressing their apologies for taking a few extra days to get back to me.I, myself, work in customer service, so I have pretty high standards for how I am treated as a customer. This company exceeded my expectations and then some, and the product they make is, in my humble opinion, one of the best available.I can't wait to try some of their other products, because I really do believe that if I ever have any issues they will be sure to make it right. I actually haven't really had issues with this phosphate test, it seems very accurate and the user experience is significantly better than competing tests. It's easy to read, with a nice, clear color card, and very clear instructions. A+ product, A+ customer experience. Well done!

good

very poor item test result not come poperly

I use this mainly in my tanks WITHOUT live plants as there isn't anything to absorb/use the nutrients in the water. My cichlid tank was having some issues with cyano and I read that phosphates could be part of the problem. I use this weekly to keep an eye on the levels giving me a good idea of when a water change is needed. No issues with cyano since.

Easy to use. Wish it had smaller increments.
