API Carbonate Hardness Test Kit for Freshwater Aquarium 1ea
Tests tap water & fresh or saltwater aquariums for carbonate hardness (KH). Helps prevent fish stress caused by rapid pH shifts, the result of low levels of KH.
Easy to use. I didn’t even realize how important it was not being in the bulk test kit.
The Nature Aquarium staff is so helpful and knowledgeable. I’m glad they recommended purchasing it.
