ALGENKALK

Marine algae to improve the pH of the potted soil. This makes marine algae, in contrast to a softer dolomite lime supply and raising the pH. In addition, it contains many trace elements that are valuable to the plants.

Angel trumpets consume calcium from the Erdsubstrat and the ground gets in the long run too low pH value when there is no longer present lime. This always happens when only soft water (rain water) is poured.
The plants then begin to look after some time, even when adequately fertilized. The low pH prevents the absorption of nutrients and the leaves usually show in the first third of the leaf a light green color.

From time to time in the water of dissolved marine algae prevents this negative development.
