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.

Master kit comes with the tubes, but I seem to break them every time.

My son accidentally broke two of the glass test tubes that came with the ammonia and pH test kits. Just when I needed it most, I had nothing. The pandemic made it worse, where Petco and PetSmart were always out of stock. So, I made sure that I ordered a set of 24 in case of more accidents. The glass is not that thick but sheer so that you can make a good color reading which is important. Im skeptical about using the plastic bottles because Im not sure how clear they would be to make a good reading. Plus, I prefer glass for the share visibility. I wish the glass was more durable though, because the cleanup SAR another issue, tiny glass pieces can be missed and end up in your Barefoot. Ouch! Overall: good for sheer visibility color check. Value: could be cheaper as glass always needs to be replaced when broken.

The test bottles themselves are fine. No complaint. Cheapest option is buying them in bulk. But the box opened up while they were being shipped. It would take one tiny piece of tape to prevent this. It ended up in me only getting 22 instead of 24. Two broke. Thankfully it wasn’t more. There’s no way to contact the seller on Amazon and my only option for damage is shipping the whole thing back for exchange. Being that I am down to one API tube without this kit and that I am cycling a brand new tank, I can’t afford to not have these tubes so I am just left with a lesser value. Hopefully the seller reaches out after this review to send me two replacements for the shipping damage.

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!

So happy to find these. Over the years I always manage to break a few. Now I don’t have plenty of vials for all my different test for my multiple tanks.

I needed these SO BAD (and will probably need more again soon). The glass tubes just break so easily, and its REALLY HARD to find more! I got this larger box, and everyone around me wanted to buy just a few off of me! We ALL needed them!

after breaking most of the test tubes that came with my testing kit, I am so happy to find a perfect solution. Everything came and no tubes were damaged

Sad these are offered in such a large quantity but luckily I have lots of tests to do. At $0.50 a pop, not exactly cheap but the best price per unit i can find. They leak when shaken, a common thing for water tests. Not good when shaking corrosive chemicals. They do break as theyre small and glass, but not entirely frail like grandmas fine wine glasses. The caps pair nicely (minus the leaking) and the tubes can be stood up on their ends. These are OEM, come with the 5mL markings, caps, and everything, but are a bit pricey. Also they leak. Honestly a big turnoff for API tubes.

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!
