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.
There are a couple different designs:
Master Kit: stores 8 test liquid bottles and 4 test tubes with the typical labels
Master + Hardness Kit: 12 test bottles and 6 test tubes
Bought this to keep my API kit tidy and it’s been great. It’s good quality and holds all the bottles well. Easy to read the levels on the card behind the test tubes too.
Super service and quick delivery
Fantastic thank you! Makes testing the water MUCH easier now I'm not knocking the tubes of water over everywhere. Very well made and loved the free sticker! Thank you
Made water testing so much easier
