Replacement tubes are great, just wish the caps were leak proof.

Bought these for back ups Incase the tubes in the kit broke or if I needed to test many tanks at once.

this is like a bad joke. The lines are not at 5ml in these tubes. not only that they don't even match each other. Some are at 3.5 ml, some at 4ml, some at 4,5. Please see images with the lines.

This nice value pack. It is amazing how easily these tubes can break. One time I had one crack in my hand. Always a good idea to have extras.

I have 3 test tube holders so I can hold 24 tubes. Sucks to have to wash tubes during a session of multi-tank testing. Do all the testing, was all the tubes. Easy.

I dropped all of my test tubes and they shattered, I bought this as a replacement, they are the EXACT same tubes (with 5 mL mark) that come with all API test kits, caps included

These are perfect for people like me who have enough aquariums that the tubes that come with the original test kits are not enough. They are the same high quality tubes API has in their kits, this way you can do more tests at once while you wait for the others to finish their wait time.

Accurate to 5ml line. Tops are just a bit leaky like mentioned. Most irritating to me was I only received 22 of the 24.

All the tubes came in perfect condition. No broken tubes and even the box is in perfect shape. The tubes themselves are just as they should be. They have lines marking 5mL and caps. A wonderful purchase to make water testing my tanks easier.

Because, you know, you might have broken a few. Much better deal to get the pack than a 3 or a 6.
