Description

The Problem

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.

Solution

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.

Question:

You do not state amount of DR-64t to mix with what volume of water to sprinkle onto the pond? Thanks Brian Portch

Answers:

  • Posted by Simon Reid on Monday, 21 April 2014
    Dilution rate is mentioned at http://hydra-aqua.com/duckweed-control.html, so you just need to wet the powder out so that it sinks to the bottom, rather than lying on the top of the duckweed.

Question:

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.

Answers:

  • Posted by Simon Reid on Friday, 7 March 2014
    You use 20g per 5sq metre treatment, therefore 100g is sufficient for 5 treatments.

Question:

How Hydra DR-64T is different from other duckweed treatments available in the market?

Answers:

  • Posted by Aj Edgar on Monday, 6 January 2014

    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.

It worked
I always knew that keeping my pond healthy would keep the weeds away, but what was the solution if the spores do fall in. I am against any chemical treatment that would disturb the water chemistry in my pond. Hydra DR solves all my problem. It is as effective on the weed as any chemical and at the same time safe like any biological product.
Review by Benjamin S.
worth the money
I was always worried about the duckweed nuisance and never knew a solution that would work without killing off my plants I seems Hydra Hydra DR-64T is the final answer.
Review by Horace Gladstone
Worked wonders
I was alarmed at the rate Duckweed covered my pond quickly. I searched the net for solution and came across chemicals that promised to kill the weed. But I was worried about my lilly pads too. Therefore I chose Hydra DR which claims to a be biological treatment. It was effective in my pond. i am waiting to see whether the promise of keeping away the duckweed is also fulfilled
