AQUAEL DECORIS Dolomite Gravel 2–4 mm 2kg – Natural Aquarium Substrate for Hard Water Aquariums

AQUAEL DECORIS Dolomite Gravel is a high-quality natural dolomite substrate specially designed for freshwater aquariums that require hard, alkaline water. Unlike inert aquarium gravels, dolomite gradually releases calcium and magnesium minerals, helping to increase and stabilise pH, GH, and KH, creating ideal water conditions for African cichlids and other hard-water species.

The 2–4 mm grain size provides a stable and attractive substrate that supports aquarium décor while allowing good water circulation. It is thoroughly cleaned, safe for fish, and free from harmful impurities. Before use, simply rinse the gravel under running water to remove any transport dust.
