Kusuri Lithaqua

Kusuri 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 Kusuri 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.

Kusuri Lithaqua neutralises acid pH and helps to restore carbonate alkalinity.

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.

• High surface area and lightweight,
• very economical and matures quickly
• Very low maintenance
• Excellent biological filtration
• Improved fish stocks due to the extra performance over alternative media
• Can be used as a stand alone biological filter or as an add on to an existing filter system

Oyster Shells

Oyster Shells have been used for years by Koi professionals to help with the pH of the water and to maintain optimal water conditions and is extensively used in Japan.

Since the Oyster Shells will generally raise the pH level in your water, these should only be used in cases of low pH.

Oyster Shell generally will raise the level of the pH.

For those that ever ever been to Japan, Oyster shell is used extensively by the breeders in Japan, these soluble (soft) shells are used to stabilise the pH.

Oyster shells stabilise the pH / KH-value which prevents pH crash. If the KH value drops to this starts to dissolve the shells until balance is reached again. Nitrifying bacteria also grows on the oyster shell.
