Biological mulm breakdown in the garden pond – ARKA Substrate Cleaner Pond breaks down mulm, sludge and organic deposits on the pond floor. For cleaner bottom zones, less sediment and a stable pond environment. Breaks down food residue and plant waste – The bacterial blend with replicated mangrove mud reduces typical waste in the pond and eliminates harmful gaseous compounds. Particularly helpful on stone and gravel floors.
