## Features

- Biological substrate cleaner for small tanks – ARKA Substrate Cleaner cleans the floor with live bacteria and breaks down mulm, food residue and organic deposits. For nano aquariums and targeted maintenance.
- Breaks down deposits in the substrate – Substrate Cleaner breaks down nitrate sources, phosphate deposits and harmful gaseous compounds in gravel and rock. With live bacterial cultures and replicated mangrove mud.
- Works deep in the substrate – The bacteria also reach areas under decor, roots and stones where deposits collect. This supports clear water, less odour and a stable biological balance.
- Easy to use without siphoning – Add 20 ml per 100 litres directly to the aquarium every 14 days until the substrate is clean, then 20 ml per 100 litres monthly. No hose, no mulm bell, no need to switch off the filter.
- For freshwater and saltwater – Suitable for aquariums with fish, shrimp and corals. Against phosphate deposits in saltwater, use 10 ml per 200 litres weekly together with ARKA Phos-Out 4.
