Aquarium test kit holder - API test kit tray

This test tube holder lets you get rid of the ugly API water test kit box, and store your tubes and reference chart in style. Space to store 4 test tubes (i'd lost one already so wish i'd designed this earlier!) as well as recessed holes to allow the test tubes to stand on the tray securely during use. (Diameter of the inset holes is 13.2mm, not sure whether it will be compatible with test tubes outside of the API freshwater test kit as haven't tested) Below the test tube tray you can store your reference chart for water quality tests. I just ripped the back page off the book that came with the test kit and it fits well in the bottom of the tray. To remove the tray, just press down on one side of it, causing the opposite side to lift up. 112mmX137mm (external measurement) Part of my Fancy Fish Accessories bundle. All of the storage solutions in the bundle have been created with the same design language and compliment each other. Check my profile for the other models.
