LITHAQUA is a marine mineral with a high content of minerals, trace elements and carbonates. It brings them into your pond and thereby adjusts the mineral balance and improves the water quality. Use it as pond substrate for bacteria to grow on and for fish to play in, or use it as a filter medium.
Modern multi-chamber filters contain mainly plastic media. Those are excellent supports for bacteria but they do not add anything to water quality. It is important to fill at least one filter chamber (preferably the last chamber) with LITHAQUA. It provides an enormous surface area for bacteria (10 to 20 times more than most plastic filter media) and provides the bacteria with essential nutrients.
LITHAQUA neutralises acid pH and helps to restore carbonate alkalinity.
