Pumice Stone Filter Media

NT LABS Zeolite 5kg

Zeolite is commonly used in pond filtration systems to help absorb and remove ammonia and other nitrogenous compounds. Recharging the zeolite helps maintain its effectiveness over time. For best results, use NT Labs Zeolite throughout the year and recharge it regularly. Consider recharging and topping up when water quality begins to decline.

How to use:

1. Place the zeolite into the filter bag provided and rinse it under the tap.
2. Position the zeolite in the filter in an area with a strong flow of water.
3. Test your water quality using NT Labs Test Kits regularly.
4. Recharge the zeolite in spring and every 6 weeks unless poor water quality is detected. When recharging, replace 50% of the zeolite.
5. To recharge, prepare a salt solution (4 tablespoons per gallon of water) and soak the zeolite chunks for 24 hours.

Black Knight Spawning Brushes

Pack of 2 specially designed soft spawning brushes each brush measures 1.5m by 140mm diameter.

Spawning is made easy with the help of these specially designed brushes. The breeding season is normally from April to July depending on the weather.

Place the Spawning Brushes just below water level, one above the other, at the edge of the pond, this will
encourages your fish to spawn, usually in the early hours.

Spawning takes several hours with the eggs sticking to the brushes.
After spawning, separate the brushes from the broodfish to avoid the eggs being eaten.
Place the brushes in filtered water of the same temperature and the fry will hatch in 3-6 days.

Small fish should be kept separate until they are large enough to be introduced to the pond.

Please Note: These spawning brushes are made from a soft material that won’t harm your fish. DO NOT USE filter brushes for this purpose

Kusuri Lithaqua Media Sack

Kusuri Lithaqua Media Sack is used with Kusuri Lithaqua Media 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.
