TestPro Alkalinity (KH)

Stable carbonate hardness is one of the parameters a marine aquarium keeper has to track regularly, alongside calcium and magnesium. This Aquaforest test kit is intended for reef and marine tank owners who need to check KH at a defined interval and compare the result against the target range.

Why it matters

• Target range: the kit is aimed at marine systems, where the recommended KH is 6.5–8.0 dKH.
• Test capacity: the supply is sufficient for 78–100 carbonate hardness determinations, within the measurement range shown in the manufacturer's table.
• Parameter scope: it covers carbonate hardness only, so calcium and magnesium need separate testing.

What it works with

The kit belongs to the water chemistry and test category for marine aquariums. It is designed for routine KH checks in saltwater systems, where the target range of 6.5–8.0 dKH applies. Pairing it with calcium and magnesium tests gives a fuller picture of the water chemistry in a reef tank.
