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, bacteria and sequestrants. 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:

Please can u tell me exactly how DR64t is different from your Eliminator of two years ago? Is it a different chemical or what? Thanks Ann

Answers:

  • Posted by Kate Griffins on Wednesday, 16 July 2014

    Dr-64T is a different product as well as bacteria it includes ingredients to sequester the micro nutrients necessary for duckweed growth thereby speeding up the elimination of duckweed.
    So it is completely different product as compared to what it used to be 2 years ago.

Posted by Yvonne on Tuesday, 27 May 2014

Question:

When is the best time of year to start using Hydra DR? Should it be quite early in the year ie, would it be effective now (end May)? Is it safe for frogs?

Answers:

  • Posted by Zoe Thomson on Tuesday, 27 May 2014

    Minimum water temperature for Hydra DR-64T to be effective is 10°C

    Yes, it is completely safe for Frogs, but as a pre-caution its best to use any pond treatment ONLY when Tadpoles have legs or Newts have passed the larvae to Juvenile stage

Question:

How long after I have applied the treatment do I have to leave it before I can turn back on the UV Filter/pump?

Answers:

  • Posted by Robin Newman on Thursday, 15 May 2014

    Switch off UV lights for 2 days after adding Hydra DR-64T and then you can restart it again.

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.

Duckweed
After trying all sorts of products this did the trick , brilliant took a while but chat line was so supportive. Well done . Review by Lorna
Looks like I have finally found a product that works!!
The pond has had two doses and (fingers crossed) it seems to be working, ask me again in a couple of months and I might give it five stars.
Review by Byron
All duckweed has been removed
Having used only 2 applications of DR-46T all duckweed has been removed. An excellent product with results far exceeding my wildest expectation.Would highly recommend to all. Review by Terry Dinsdale
Weedless at last
"This product is easy to apply and seems to be very effective. I have applied it twice and no more weed has appeared.
"
Review by Peter
Remarkably good
I've used the blanket weed treatment from this seller for years but never thought of trying the duckweed treatment. I was so bored with scooping it out and so reluctant to do so when I had a lot of tadpoles that i simply lived with a pond which looked like a large lawn. The duckweed ruined the lilies too.
At first I thought this was no good because there is no "instant" effect as there is with the blanket weed but after about a week WOW! The surface of my pond is now clear, I can see the bottom, the lillies are starting to flower. I'm delighted - many thanks
