API Replacement Test Tubes for Aquarium Test Kits 6 Pack Bundle

Original came broken but was replaced for new ones within 24 hrs. Overall good same as original

Just like the originals that came with my test kit.

Broke both of the tubes that came with my test kit and these are exactly the same. Survived shipping due to extreme caution of shipper (was wrapped in multiple layers of bubble wrap and packaged in a large box).

Theyre the same exact ones that come in the test kit. I just find it so annoying that they break so easily when trying to get the cap off. You have to be super careful because the cap starts to grip the glass tightly after a few uses, and if you squeeze to hard, the glass breaks in your hand. Ive learned to be ultra careful and gently twist back and forth. Im very petite, with small hands, and Ive definitely drawn blood a couple times after breaking a tube (its fun when you break a tube of chemicals into your hand). Not a good value if they break so easily. Use at your own risk.

The API replacement tubes were bought to replace a tube from the original test kit which became stuck in the rack and broke upon its removal. Not only was this purchase a perfect replacement tube, the extra tubes also greatly augment the kit which actually has more potential tests than tubes, if the PH test range nears the overlap point. Having extra tubes is a time saver when testing multiple tanks and ponds.

N?A

These did not come in the box pictured in the listing, but they are exactly like my original API test tubes. I broke two of my originals so I needed to order these. The price was somewhat reasonable. Nothing to complain about here.

Perfect

All I needed was one. What am I going to do with the rest?

I used it to keep the water safe for my fishes, it was easy to follow directions and the price is great
