Relief to Use
These are relatively easy to use and accurate. They are the same tests my LFS uses and my tank maintenance person uses. It is a great value for the money and a good accurate test kit for the average aquarium owner. My LFS still does testing once a month to ensure accuracy but this helps to catch anything going south with the tank in between maintenance visits.

Good for the money, tells you where your water quality is.
Work pretty well, not always the most accurate but if you know basically what you're looking for these work great. They don't always measure traces correctly, but traces don't mean much. Fast easy and gives you a good idea of tank water condition.

Tried and true even over Hannah
I have all the Hannah checkers and guess what? I still revert back to the easy drop tests. Some of the Hannah checkers are cumbersome and it is easy to just fill the test tube and add applicable drops and shake. Hope they don’t stop making these test kits. Everything is included to use. Very efficient.

Perfect for cycling
I didn’t want to buy expensive handheld testers for parameters I would only be consistently checking during cycling so this kit was perfect for that. Like any colorimetric test, reading the results introduces some error but that’s what you will get for most lower end test kits anyway. As far as accuracy I would say test strips < this test kit < handheld expensive test instruments android this is a good bang for your buck. The tests are easy to set up quickly, I wish I purchased this sooner!

A must have for aquatic maintenance
A must for aquarium and biofloc maintenance. Please mind that this kit is salt water or high ph kit, hence you will receive only high ph testing reagent. If you require low ph testing reagent, then go for fresh water testing kit. Although high range ph testing provide you with results from 7 and higher ph, which is enough to serve the purpose of aquarium and biofloc (since 7-8 ph is necessary to maintain). Overall good product.
