API Replacement Test Tubes for Aquarium Test Kits 6 Pack Bundle

nice

Perfect for testing fish tanks

Very satisfied

The test tubes came in on schedule. None was broken in transit. Was packaged nicely.

Muy buen producto

My Betta thanks you for the glass test tubes to check his water condition. Glass just seems better than plastic in this case. Happy with this purchase and that it arrived timely and in perfect condition.

Theyre perfect! I ordered them to replace one Id broken, and then realized I had enough to test all my tanks at once! I cant tell the difference between these and the ones that actually came in the kit. They are perfect!

If you have an aquarium you know that you need these. And I have already gone thru a pack of these. This is my 2nd. I dont know if they are just thin or Im just too rough. But Ive had tanks for years and in the last 6 months Ive gone thru the original 4 from the master test kit and a extra pack of 6. I have broken 2 from this pack. Just regular use. These are labeled as API. They have the lines to where you add the water. So caution when using, especially with children.

Just like the originals that came with my test kit.

Product was great and replaced what I broke
