API Freshwater GH & KH (Hardness) Test Kit

API Freshwater GH & KH (Hardness) Test KitTests tap water & freshwater aquariums for general hardness (GH) and carbonate hardness (KH). Helps prevent fish stress caused by rapid pH shifts, the result of low levels of KH.

Tubing Material: Silicone

with a less toxic form of malachite green

Always include a drip loop when plugging aquarium appliances into the electrical outlet

dose according to a measured uptake of Calcium KH/Alkalinity and Magnesium using Red Sea’s Foundation Pro multi test kit

Slowly fill hydrometer by dipping bottom corner fill port below water surface until water flows up and over inner weir

sunrise and sunset with no additional controller needed

Iron is immobile in plants

MatrixCarbon outperforms other high grade carbons by at least two-fold when compared for total capacity to remove aquarium organic matter

for reasons typically due to sub-optimal storage and handling of the cysts

The Mag-Float’s Powerful rare earth neodymium magnets enable the easy removal of algae

It is designed to restore and maintain alkalinity in the reef aquarium and provide calcareous species with the essential carbonate needed for growth
