Aquavascular Kalrich is an easily utilizable potassium fertilizer for aquatic plants.

Potassium deficiency is manifested by pinholes in leaves, yellowing of edges , chlorosis and necrosis. Kalrich quickly replenishes the deficiencies of potassium. Kalrich works effectively and results can be seen in a short span of application.

Compatibility

Freshwater planted aquariums. Kalrich is a single-element fertiliser: potassium, in a form Aquavascular describe as readily utilizable, and nothing else.

Use it when the plants show it. The symptoms Aquavascular name for potassium deficiency are pinholes in the leaves, yellowing along the edges, chlorosis and necrosis. Pinholes in otherwise healthy older leaves are the classic tell. Aquavascular say the response is quick once it is dosed.

Where it fits alongside the rest. Potassium is the one macronutrient a tank does not generate for itself — nitrate and phosphate arrive from food and fish waste, potassium does not — so it is the element most often short in a planted tank that is otherwise fed. It is a natural top-up next to an all-in-one such as Complete Nutrition, and unlike a nitrate or phosphate dose it does not feed algae in the way those two can.

Pack Size

250 ml.

Aquavascular do not publish a dose for Kalrich, so there is no honest way to say how long a bottle lasts — see the note below.
