API Replacement Test Tubes for Aquarium Test Kits 6 Pack Bundle

I honestly cant even tell the difference between the original and replacement tubes. The picture is me using them while testing my cycling tank.

I ordered these because my original test kit already has two test tubes that broke. I ordered these because I thought they came in the box to store them but to my surprise they came in a small bag. The bag was bubble wrapped and that’s the only way they got here without breaking. Actually it’s a small miracle they were not broken but I expected it to look just like it shows on the ad. For the price I paid it should’ve come in the original box. Maybe I’m the only one that got it shipped this way. Just be aware. That’s actually not being accurate and rather deceptive I think.

When I do weekly water changes, I like to check the levels of everything in my tanks. Seeing as I have 5 tanks, there was not enough vials to go around in the Master Test Kit. I ordered a few of these and problem solved. They have held up well over a few months, except for when dropped. They like to break when dropped onto anything other than carpet, but they’re glass so I’m not really too surprised by that.

The packaging was very poor. Considering these are fragile glass test tubes, they were just wrapped in a thin plastic bag and thrown in a box with other, heavier items (I ordered multiple items from Amazon at the same time). I expected for them at least to be bubble wrapped. I am still amazed that none of them broke! Other than that, a good genuine API product, as expected.

These tubes are exactly like the tubes that come with their master kits. No issues with the tops or inferior materials. I will be ordering more when I wear these out.

Love these tubes and they came without being broken. Will say that maybe the packing could be better? Was delivered in a box (thank god not a soft pack) but tubes were in a plastic sealed bag that was rattling around in the negative space in the box. Maybe wrap in bubble too? Could have definitely been broken when we got.

They’re ok with caps; but there’s no measured fill line for the tests! Since they’re API- they should have the fill line on each vial for the each test.

Comes in good condition. Easy to read when doing test for fish tank.

Buyer beware!! Item does not come shipped in box as advertised in photo. Item comes wrapped in bubble wrap and tossed into a shipping bag or box and gets tossled around and arrives damaged. Otherwise item is exactly as described as long as you can receive without being damaged from shipping.

I finally broke enough to need replacements and these were perfect!
