A very helpful piece of equipment to have on hand.
Before, when I was using my various API freshwater test kits I was just sort of propping the testing vials here and there, scattered about my table top.This litte rack really helps complete the aquarium water testing task!It is solidly made and works very well holding the test tubes while tests are being performed, as well as helping to dry the rinsed-out tubes for storage.Plus, it really looks nice; you can tell care was taken in making this product. I really like its appearance!

Wow
To be honest I bought this because it had an elephant on it and it was WAY more appealing than others offered on Amazon. It arrived as promised 2 days (but swear it was sooner).The packaging was awesome thick cardboard securely taped with another thick piece of cardboard inside, a perfect fit!I was amazed at how sturdy it was and well made. All the edges are clean just perfectly made and sparkly. The two dainty white elephants on the sides are a perfect touch and made me smile. Just ordered two more.

Awesome little rack, perfect for API test tubes
This little rack holds your API test tubes while you are testing and stores your empty ones while they dry. It makes water testing so much easier and reduces the risk of breaking test tubes 10x over. It’s well made, well packaged and shipped with a nice little note from the seller. I highly recommend it for anyone who keeps aquariums and uses the API Master Test Kit.

Great Product!
I didnât even know I needed this, now I donât know how i lived without it. Before, i used to just keep all of my test tubes bouncing around in a red solo cup. Now, I have a great place to keep everything organized. And no more accidentally knocking over test tubes! Every serious aquarist should own one. Bonus: it comes fully assembled!

Almost perfect after design change, needs additional improvement.
This is a great little test tube rack that fits the API aquarium test tubes perfectly. Many previous reviews mentioned that the drying posts were useless as the older design allowed no air flow into the inverted tubes for them to dry. This newer design has apparently added a riser on one side of the posts to lift the tubes off the base to allow for that air flow.But, as some other reviewers had also mentioned, the six staggered positions are not in the best configuration. It would be nice to have a straight line of holes, with spaces in between, so that water parameters can be read against the reference card without removing them from the rack. As is it, the tubes cannot be easily aligned with, or compared to, a reference card held behind.Future design should have a straight line of appropriately spaced holes, and a post in the back so that the reference card can be held in place behind the tubes for easy reading.Still, a nicely made tube rack for API test tubes.

stable and clear
works well, doesn’t fit the API test tubes completely but does the job.

Exactly what I needed for aquarium testing!
I cannot tell you how many glass test tubes Iâve broken over the years because I just stood them on the counter. One bump and one would fall into the other like dominoes and theyâd roll to the floor. Not anymore. These will stay happily nested in their stand!It has 6 spots that is the perfect amount. Iâll test ph, kh, gh, ammonia, nitrite, and nitrate. Donât need any more than that usually. I can easily see the colors as they develop.Also, I used to dry them upside down on power towel. But I notice it just makes the humidity build inside because itâs not airing out properly. Now I have a drying rack that keeps the bottom open for the water to run down.I donât know why I went so long without getting this. The cost alone pays for itself since I wonât be breaking the tubes anymore!

A fish product you actually need.
If there is one thing I would recommend all new fish keepers get, this is it. I cant tell you how many test tubes I’ve broken. Its so easy to take the cap of just a bit too hard. Or to put a tube down on the counter only to hit it with your hand grabbing the next one. This holder has saved me breaking any more tubes, and gives me a spot to place them to dry once I’m done. I love this product.

This is a great test vial rack for the API aquarium test vials. The acrylic seems to be quality stuff, and it is well designed and put together. It feels solid and durable. The size and design are perfect for the API test vials. It holds 6 vials securely in place in two staggered rows so you can clearly see all 6 vials at once. The drying posts are solid and are a great place to store the tubes. There is enough space for you to insert the colour reference card(s) between the test vials and the drying posts, so the rack convenient holds up the reference cards right behind your vials. This is very convenient for interpreting your results and making a colour match on the scale. Really the only small drawback to the design that I can find to pick on is that there is nowhere to hold the vial lids. You can place them on the flat surfaces of the rack, but there’s nothing to keep them in place if you’re moving the rack around. This is a minor concern, really. I just use a small plastic box ($1 store fodder) that fits very nicely between the two shelves of the empty rack. I keep my vial lids and magnetic stir bars in it. That works very well. Having a little box in the design to put the lids in would be a nice touch, sure. Not having it is really only enough to justify loosing maybe half a star at the absolute most, but not nearly enough to cost a whole star. Since you can’t deal in partial stars here, my review rounds up to 5 stars. The quality workmanship on display here soundly trumps my nit-picking.This same seller, Tilly Concepts, also sells a really nice set of replacement glass vials for the API test kits. Quality glass, accurate 5 ml markings, but the real must have feature is by far the screw on caps. Finally somebody has solved the 2 biggest problems with the stock API vials – they break easily and the lids leak like crazy. The TC vials do neither of those things. They’re great. Get a set to pair up with this rack and you will not be disappointed.

There is nowhere to store the test tube caps.
