Green or Dirty Water Treatments
|
Green Water: What has happened?
Microscopically small algae, also called killer algae or algae bloom, reproduce explosively in rising temperatures (above 15°C) and colour the water green.
What can happen without treatment?
Underwater plants die due to lack of light. Fish suffocate due to lack of oxygen (although algae produce superfluous amounts of oxygen during the day, they use this up during the night). |

I-tronic electronic algae control |
 |
- Developed from space technology, copper anodes generate pulses of positively charged copper ions which form a natural barrier against algae
- 230/9 volts, 5 watts with adjustable power and timer functions - Energy efficient
- Clears green pond water, particularly string algae (blanket weed) and algae bloom
- Harmless to fish, plants and animals
- Facilitates healthy balanced eco system and improves pond odour
- Suitable for ponds up to 75000 litres

Extract of Barley Straw: 500ml treats a 9000 litre pond for 6 weeks |
 |
Naturally clears green water and blanketweed (string algae) from ponds. The extract works at least one month quicker than ordinary barley straw and is far easier to control. It provides the bi-product of the straw breakdown that kills algae. It is also harmless to all vascular plants and all water bourne wildlife. |

Clear Pond: 1 litre treats a 22,730 litre pond |
 |
Murky Ponds are unattractive and prevent viewing of the fish. Suspended particles also affect fish and plant life because they block delicate gill membranes in fish and cut out light to submerged aquatic plants. Clear Pond clumps together the fine suspended particles and quickly clears dirty; cloudy water and aids filtration. |

Filter Zeolite: 5kg |
 |
• Zeolite binds Nitrates and Phosphates. It is a high performance natural product, a proven filter material thanks to its crystalline surface , which is a 1000 times greater than sand. This large surface area promotes settlement of micro-organisms and hence the breakdown of toxic ammonia that occurs through fish waste and unconsumed food. It also withdraws the nutrient base for green algae and thus prevents turbidity.
• Can be used in filters and moving pond water, 35 x 40cm fine mesh filter bag supplied.
• Sufficient for 5000 litre pond without fish, 2500 litre goldfish pond, 1250 litres Koi pond.
• Effective for 3 - 4months; change mid season for optimum pond water quality.
• Ideal for replacing Phosless in Oase Biotec Screenmatic Filters. Biotec 12 = 6kgs max; Biotec 18 = 9kgs max; Biotec 36 = 18kgs max. |

Phosless: Filter Media Tube Set: treats up to a 10,000 litre pond |
 |
Oase Phosless is a natural product which reduces algae growth by binding excess phosphates. Twin tube set fits Oase Biotec 18 and 36 filters , the Oase Proficlear Phosphate Binder Module or can be placed directly in moving water (i.e. filter or watercourse outflow).Supplied as a combination pack including one Phosless CA media tube and one Phosless FS media tube.Phosless CA is a white, porous calcium mineral for binding phosphates and heavy metals (such as copper and lead).Phosless FS is a brown, grainy iron mineral which effectively binds phosphates and sulphide.Particularly useful during warm or summer months. Active for up to 60 days. The bound phosphate can be disposed of as a fertiliser additive to potting soil if desired. |

|
Phosless LM: 30 litre Bulk Set for ponds & lakes up to 600,000 litres |
 |
For effective nutrient withdrawal and green and string algae prevention, Phosless LM is supplied in a combination pack with one bag of Phosless CA and one of Phosless FS. The use of two different materials is ideal because the binding mechanisms for phosphate are extremely complex and they can be prevented by competing reactions with other ions, low oxygen content or low PH values. The contents of the bag can be introduced wherever it can be carried away by moving water - we recommend introducing Phosless LM in the flow area of the Aqua Air 250 LM Aerator for maximum efficiency. |
