Full Instructions on the label.
Duckweed or Lemna Minor is a small perennial aquatic plant that thrives well in shallow water bodies that are rich in nutrients (usually because of decaying organic matter). It floats on the water covering the water surface in the form of carpet like foliage. The thick covering of duckweed cuts out the sunrays from entering the water and therefore killing all other underwater plants. Duckweed multiplies very quickly matching the growth rate of higher plants. In ponds with excessive presence of phosphates and nitrates, duckweed can double itself within 2 days. Stagnant ponds, sheltered from winds and current also encourage duckweed infestations. Duckweed easily spreads through water birds and is small enough to be carried around with strong wind currents. Duckweed has even been reported to be found inside of hailstones.
Hydra DR-64T is a biological treatment containing a powerful blend of enzymes and bacteria. The product removes and suppresses the duckweed growth and resumes the ecological balance of the water.
Hydra DR-64T modifies the water quality and reduces excessive nutrients on which duckweed thrives; thus starving off the existing growth and preventing new growth. A biologically balanced pond does not experience duckweed problems.
Hydra DR-64T can be used safely for duckweed control in gold fish or large koi fish ponds. The product is suitable for use in boundary water courses, zoo ponds and leisure fishing lakes. Water bodies undergoing intensive aquaculture operations including angling clubs, fish farms or live stock holding tanks also experience duckweed problems, where Hydra DR-64T proves to be a perfect solution.

Hydra DR-64T 100gm is stated as being sufficient for 5 sq meters surface area. Could you tell me if this is for ONE application only. ie. no repeats doses over that area.
Is this a new product? I tried your last one with a little success. When I tried to get some more i seem to remember it wasnt available so I tried your blue dye without any success. Thanks Robert Coombs
How Hydra DR-64T is different from other duckweed treatments available in the market?
Hydra DR-64T is a completely biological product unlike other available treatments which may prove deleterious for fish and ornamental water plants. The powerful bacteria and enzyme blend removes the essential nutrients on which duckweed thrive. The product improves the water quality and dissuades the return of Duckweed bloom.
