This comes with one api glass tube which is nice if you did not buy the master test kit and do not have any tubes. Also nice to get another one since they are fragile. Same stuff that in master kit, but without buying the kit.

If you keep shrimp this is a must have to make sure your water gh and kh are perfect. Without proper water hardness shrimp cant molt and if they cant molt they die.

The product did as advertised, when used properly it will give you results of copper in aquarium water.

The accuracy may depend on what you are testing but I used this with Fritz Coppersafe and found it very accurate. The Seachem copper kit was not accurate. I made a test bucket of the amount of copper I wanted for my tank and made sure the colors matched that's how it worked best for me.

If you can read copper or any test kit from experience this will do just fine

I needed to test the copper levels for the Cupramine treatment I was using in my quarantine tank. Considering I try to operate on a budget with my aquarium related expenses I felt this test kit offered a good value for the price. I did learn initially that the bottle requires quite a bit of shaking to get accurate results as the solution may settle if not used or kept in storage. Also depending on the lighting in the room (warm vs blue) you may interpret the results differently. The PPM value ranges on the test kit card don't give you the greatest accuracy but I think generally speaking can keep you within your desirable range. For just needing a basic test kit for my nano tank it fits my needs but if I had a large or valuable collection of fish I'd probably invest in something like the Hanna.

Yup it works. Tried with RO water and it was clear. Tried with my tank water and it was yellow. Now, I'm not sure how accurate it is but it does tell me I have copper in my system. Make sure to read the instructions
