Vortex Brushes

Mountain Tree Spawning Brush

The spawning brush emulates natural koi spawning environment. During the spawning period, koi are sensitive to the environment. Without a comfy, soft home, they may spawn on hard rocks and walls. Thus providing them a comfy home for eggs growth is essential part of success spawning.

• Soft and resilient filaments, non-toxic, safe for fish egg
• Stainless steel core can be bent when being used
• 1 loop or 2 loops at ends optional , easy for installation and maintaining
• Modest density for collecting fish eggs ensure high survival rate

Comfy Home for Fish Egg Growth

During this special period, koi are sensitive to the environment. Without a comfy, soft home, they may spawn on hard rocks and walls. Meanwhile, touching coarse material in a pond can lead to a risk of injury or unsuccessful spawning.

The Mountain Tree Spawning Brush is made of soft stainless steel coupled with appropriately dense nylon filaments. Fish will feel a smooth, comfortable surface that they can lay eggs on.

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.

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.
