Alfagrog

Alfagrog is a porous foamed ceramic material, which is lightweight, strong and inert.
It’s high surface area makes it the natural choice for colonisation by micro-organisms in biological filtration systems resulting in cleaner water.

The Alfagrog range of porous ceramic filter media is made under controlled conditions UK.

Selected clays and raw materials are rapidly sintered at high temperature to produce a foamed ceramic porous mass, which is crushed and sieved to a convenient particle size.

Alfagrog is available in a wide range of sizes giving the end user optimum media surface area in varying water flow rates.

The manufacturing process ensures that no substances are present to adversely affect the health of fish or plants. The material is pH neutral and can be used in both freshwater and marine applications.

Why is it so effective:

The key to effective biological filtration is choosing media with the highest surface area possible to allow beneficial bacteria to colonise and remove waste from the water. Alfagrog has an extremely high surface area by volume compared with other types of filter media on the market.

Alfagrog is very inert and soon colonises with beneficial bacteria. Alfagrog is made of a highly porous material that contains many thousands of tiny pockets in which bacteria can thrive making in an ideal material for biological filters

Its only draw back is its sharp on the hands when cleaning so please wear gloves..

Benefits over other filter media:

• Extremely high surface area
• Highly porous
• Inert, pH neutral
• Lightweight
• Available worldwide
• Economical
• Available in 15kg sacks

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

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.
