History
Frank Sawyer MBE pioneered the use of chalk as a fishery management tool. He conducted large scale chalking projects on rivers and lakes in the 1960s and 70s based on his observations on the benefits of chalk made from the 1930s onwards. These chalking experiments were repeated in France and other countries with similar results. Sawyer was never able to work out completely the science behind his observations but he was adamant chalking was a highly beneficial fishery management and river keeping tool. He wrote about his observations in various magazines and in the groundbreaking book 'Nymphs and the Trout' while Sydney Vines expanded the subject further in his biography of Frank Sawyer 'Man of the Riverside.' Sawyer observed the following benefits from chalking:

• Rapid fish growth
• Healthy and vigorous fish.
• Improved levels of oxygenation.
• Greatly improved fly hatches.
• Clear, sparkling water.
• An explosion in snail, crayfish and crustacean numbers (important food sources for trout).
• Significantly reduced levels of organic sludge.
• A decrease in algal blooms.
• Reduced water acidity.
• Decreased fish mortality.

OxyChalk® is based on the same high purity chalk used by Frank Sawyer but has important natural and biodegradable additives that enhance the beneficial effects of chalk. The unique manufacturing process also imparts important properties to the product. OxyChalk® is 100% biodegradable, environmentally safe and harmless to humans, fish, birds, animal life, pets and aquatic plants when used in water at the specified dosage rates.

How OxyChalk® Works
OxyChalk® works by boosting the natural beneficial biological activity of the water being treated. Although immediate effects will be seen, such as a reduction in water turbidity, it takes 3-4 weeks for the water's natural biological activity to be boosted to maximum levels. This boosted activity will continue for 2-3 months after the initial application.

OxyChalk® should be used on all waters that require intensive care to bring them back up to a high standard. Problems that OxyChalk® can improve include discoloured and smelly water, poor oxygen levels, algal blooms and bottom sludge.

Application
OxyChalk® should be applied evenly by surface scattering at the rate of 250g per m2. Larger or repeat applications can be made for waters in poor condition. OxyChalk® is biodegradable, natural and harmless so there is no risk of overdosing.

OxyChalk® should be used on waters in poor health as a means of improving conditions for fish keeping and can be used generally on all waters to maintain and enhance the condition of the water. The special additives in OxyChalk® include a natural flocculant that causes suspended matter to sink to the bottom where the special chalk and beneficial microbes rapidly decompose organic waste.

OxyChalk® can be used at any time of the year but will have most effect if used in the spring. Ideally, the main application should be in the spring with maintenance doses of half the initial application made every couple of months thereafter.

Some species of fish are particularly sensitive to any change in the environment. No fish have ever been reported harmed by OxyChalk® as it is gentle and natural product, but fish owners are advised to dose ponds by section if particularly sensitive species or specimens are present. By dosing a quarter of the pond every 24 hours, sensitive fish can move slowly from a non-treated to a treated part of the pond in their own time.

On initial application the water will take on a cloudy white appearance. This will dissipate within a few days and a light covering on the bottom will then be observed. This will slowly disappear as biological activity increases. Filtration systems should, if possible, be switched off during application and for a few hours afterwards.

Ingredients
OxyChalk® is a specially formulated mix containing fossilised coccolith powder, powdered calcium montmorillonite clay, beneficial microbial spores and essential microbial nutrients, enzymes and minerals. All components of OxyChalk® are 100% natural and biodegradable.
