Colombo Natura Mearl 2500 ml

Natural minerals for a clear and healthy pond.

Granules for easy dosing based on lime from sustainably harvested algae.

Maerl has 2 main properties: it stabilises the hardness of the pond water and with it the pH.

Due to its natural origin, Maerl contains important minerals and trace elements.

These are not only beneficial for plants, but also for the development of bacteria.

Both properties will ensure a healthy and stable biological balance in your pond.
