Stabilisation of the water in the rowing machine tank
Ideally, use the manufacturer's special chlorine tablets to stabilise the water. The high-quality maintenance tablets dissolve slowly. Simply place one tablet in the tank every 3 - 4 months and it will remain free of deposits, limescale and residues. One set contains 6 chlorine tablets and is sure to last for 1 1/2 to 2 years.
You want to color the water with a rich blue? Then the blue watercolor is the right choice for you.
