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

The picture is not what I got. What I got was the API testtubes which I am happy with. They are the exact same that came with all the API tests that I already have. And to make your life easier if you have a bunch of these get one of these: Karter Scientific 208V2 Plastic Test Tube Rack for 12/13mm Tubes, Holds 50, Detachable Its a perfect fit.

First, I hate that you have to buy a package this big. I wish they made smaller packages with maybe 4-5 tubes instead of 24. This was packaged very poorly. It was thrown into a huge box with some fish food I had purchased and had 1, I repeat ONE, air packet protecting the product. 3 out of 24 of the tubes were broken and there was glass all over the box. If I had received 20 or less I would have sent it back. Over all the test tubes are clean and the caps are very snug. I use these with my API master test kit. I suppose I will order again if I ever need to.

Its nice to have extra test tubes on hand when testing my tank parameters. These come in handy when I accidentally drop one. Whatever you do, dont soak them in vinegar to clean as it takes the white marker line off, so you wont have the 5ml line as a guide.

I am glad that I ordered these. I have the API mater test kit for Fresh Water and I dislike running out of test tubes. This solves that problem. Now I can wash them all at once and be ready to go. The lids are nice and tight on the tube so that I dont spill while shaking the solutions. They are durable and I can tell that they will last a really long time.

Needed new vials as my old ones were a bit cloudy. These are perfect and exactly the same as what comes with the testing kits.

I broke a few tubes in my API test kit and was very relieved you could buy replacements. These seem to be more solid than the ones that came with the kit, or maybe I’m just more careful now. You get a whole lot of tubes in this box so I don’t think I’ll need to buy any more for awhile. Very convenient, good purchase!

My clumsy self cant seem to stop dropping these darn things, so being able to buy 24 replacements is a blessing. These test tubes have given me new motivation to track the water quality in my three tanks. Straight-up magic, I swear.

of course these are great but I (or anyone I know) would ever need 24?! Should really make a smaller box. I only wanted a few extras since I broke one of my own. Also there was no bubble wrap around them. This box was thrown into a large amazon box. I have no idea how none of them managed to break.

Just as expected.
