API test kit holders - mountable
API Test Kit Holder - Mount these inside your aquarium cabinet or on the outside of aquarium stand to hold your API test kit bottles. Old and new sized bottles fit in these. These are 3d printed to order and come with mounting holes to screw in place. See the photos for how I have installed them Updated - Nitrite & PH holder added for those who only use the standard PH test, this combines well with the Nitrite test which is only 1 bottle Price $15 each holder or 5 for $60
