Aquarium Test Tube Holder, Hand-Made Rack, with 6 Holes and 6 Drying Poles, customised for use with Aquarium Test Tubes Including API Test Tubes, by Tililly Concepts

Incredibly attractive and useful for a reef keeping wet bench, or water testing rig.

Great product!

A very nine glass item, fast shipping.

5 STARS!! I love everything about this Test tube rack. I have to test my aquarium water very frequently and this rack has made the task so much easier for me. It’s just the right size to fit my API test tubes which was also a plus but what took the cake was the drying rack.

I received this item broken....very cheaply made...not happy and do not recommend it

When only doing two tanks this is great! You can use a dry erase marker on it to mark which tank is which. And we love how it dries the tubes only wished it also had nubs for the lids too. For things to possibly look at in the future maybe doing larger ones for multiple tanks. We have 8 tanks ourselves and sometimes I like to do all my tanks at once to make it easier lol.

Simple to clean. Holds api tubes well.

This test tube holder allows me to do multiple testing on multiple aquarium setups without risk of the vial being knocked over. It is so very helpful, I don’t know how I went so long without one of these. Fits the API 5ml test tubes perfectly.

I use this to hold my test tubes for testing the saltwater in my reef tank. Tubes stand up in their slots so I can add reagents, and when I clean them they go upside down on the little drying posts. Its perfect, well made, simple and effective. I love it!

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.
