Lithaqua is a marine mineral high in trace elements and carbonates, ideal for raising KH values. A superb filter media of porous construction, allowing a huge surface area for the growth of beneficial bacteria.

Modern filter chambers contain many and varied plastic media, these provide good support - but Lithaqua goes one stage further. Not only do the beneficial bacteria draw on nutrients from the mineral support, the media has a massive surface area up to 20 times greater than most plastic media. Lithaqua is a biological media not intended for mechanical stages. Use Lithaqua in a clean water chamber after mechanical removal of waste. Lithaqua is far more efficient than crushed oyster shells, and the high level of carbonates will improve carbonate alkalinity in soft water regions, neutralising low acid pH and buffer swings in pH.
