Review on 🧪 Enhanced API Replacement Test Tubes with Caps - Ideal for API Freshwater Master Test Kit - 24 Count Box by Isabella Baez

I have 3 reservoirs and my friend has 3 reservoirs so this kit is great for not having to constantly unload, clean, dry and refill new tubes after each set of tests for each tank . I would suggest placing a $6 test tube rack somewhere on the Revane so you don't tip it over and break it like I have in the past. I love these test tubes though. You can tell it is genuine API brand with correct 5ml sizes and well sealed caps on the tubes. No complaints here. If you are an experienced aquarium owner who tests as often as I do, or even have more than one aquarium, then this kit is for you. They are genuine, seal well and have a volume of 5mL, which is enough to test multiple reservoirs at once.
