Sludge in a garden pond

Half a Bag Treats 5,000 gallons (24m)

Sludge occurs in slow moving and static water at the bottom of ponds and lakes. It basically consists or organic waste from fish excreta and dead plants that drop to the bottom and becomes a thick brown sediment. The nutrients in it can promote the growth of unwelcome and harmful bacteria which in turn can reduce water quality affecting both flora and fauna. It can also make the water look cloudy and unpleasant. At worst it can produce noxious gases such as H2S (Hydrogen Sulphide) which give the smell of rotten eggs. All in all it is a bad thing to have and a good thing to get rid of.

RED LIGHTNING has been developed scientifically to release bacteria which colonise the layers of sludge and degrade the organic matter.

The bacteria in RED LIGHTNING have a broad range of metabolic activities producing a specific range of enzymes which break down fish excrement and uneaten food, dead plant matter and other materials which cause sludge leaving the water crystal clear.

The enzymes produced by RED LIGHTNING bacteria include Amylase which degrades starch, Cellulase which degrades plant and vegetable matter, Lipase which reduces fats oils and grease and Protease which degrades proteins.

One Acre = 4000 Square Metres requires 30 bags now and 15 per month until clear. In calculating the volume of water to be treated we have assumed an average depth of ONE METER but for water of a greater depth you will need additional treatment. Add 50% more for every additional 500 cm

Helpful hints: In hot weather you MUST keep your pond aerated. Use a fountain or other method to keep oxygen in the water. TURN OFF your Ultra Violet Lamps when using Red Lightning as the bacteria in it will otherwise not survive.

Red Lightning is a vegetable powder on which are fixed trillions of freeze dried bacteria. These bacteria come to  life when hey come into contact with water and multiply to become
huge numbers which then commence sludge treatment.

APPLICATION: Red Lightning has been designed to work in tandem with GREENLIGHTNING and consists of freeze dried bacteria fixed to a base material (maize) When these bacteria come into contact with water they become active and produce the necessary enzymes to control the sludge. Red Lightning comes in handy water soluble bags in varying weights as shown on the cart. Simply throw the bag into the water where it will dissolve and release the bacteria. The overall results are effective control of sludge and greater improvement in water clarity.

Smaller Pond Treatment

The recommended doses are listed above but please remember to store the unused Red Lightning in a dry place. Where the water temperature is low put chosen contents into a bucket of warm water and leave over-night in a warm environment. Next day tip the contents into your pond. Repeat every 2-3 weeks until all the contents are used.
