sera gH-Test

sera gH-Test

Makes it easy to monitor the total hardness

·         reliably determines the total hardness

·         easy to use

·         supports mineral balance

·         recommended action for too hard or too soft water

·         for approx. 420°dGH measuring capacity

For approx. 420°dGH.

In case of too low GH values we recommend sera mineral salt. High total hardness levels can be lowered by mixing in R/O water.

For creating soft water we recommend adding sera blackwater aquatan or filtering through sera super peat.
