Aquarium Test Tube Holder Rack API Saltwater & Freshwater Master Test Kit Marine
Test Tube Holder Rack for the API Freshwater Test Kit. This is just for the rack/base - TEST KIT NOT INCLUDED.
The API Freshwater Master Test Kit is the gold standard for checking the water chemistry of your aquarium.
But it comes in a really poor quality container that is impossible to use regularly. Using this design and a syringe, I am able to keep test time to under 2 minutes.
This version is the "Master + Hardness" Kit: Holds 12 test bottles and 6 test tubes
