API REPLACEMENT TEST TUBES WITH CAPS For Any Aquarium Test Kit Including API Freshwater Master Test Kit 24-Count Box

Two original tubes were broken during the tests. I hope these last much longer. Good price.

Good value for the price. I just wish the caps were tighter. If I shake too hard liquid leaks from the caps.

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.

Needed more than just the 4 tubes included in the master test kit. This was exactly what I needed!

These tubes are exactly like the ones in the aquarium test kits and are sold in abundance of 24 tubes and caps for almost nothing! I highly recommend this product and seller!

I have too many tanks and like to test them all at once so I needed more test tubes. Came intact and just the same as the tubes I from the freshwater master test kit.

Good value and quality.

I got these extra API Test Tubes because I have 3 tanks to do water tests. All 24 pieces of tubes are intact. Non are broken from the delivery. One downfall I noticed is one new tube I used lightly leaks from shacking the tube. That’s why I have extras! Overall, they are worth it!

Perfect tubes! :) Sure, sometimes they leak if I dont fully push the top closed, but thats a me problem, not the tubes problem. Having all these extra tubes helps me out on water change day so I dont have to keep rinsing out the same 4 tubes to test all my tanks :)

These are the ones to buy! Everything is perfect, as expected.
