Features & Advantages

  • Hydra Lake Clear is an eco friendly composition of sequestrants and natural minerals that quickly removes blanket weed, string algae and slime.
  • Completely biodegradable product with action similar to that of barley straw minus the long waiting periods.
  • No need to wait for weeks to get results, no bad odour or decaying straws to remove from the water.

Usage Rates

Initial treatment

Full instructions on label.

Hydra lake treatment gives you fast and effective results for lake algae removal. You should be able to see the results soon after the application. Broadcast the product as per the suggested “initial treatment” dose.  Wait until blanket weed dies or turns grey after which it floats free on the water surface. You may now remove the dead lake blanket weed manually or leave as it is on the water surface. The dead weed sinks to the bottom eventually where it decomposes over time.

Some stubborn growth of blanket weed may require re-treatment. Re-apply Hydra Lake Clear on such difficult patches after one week.

Note: Wait for 5 days after the treatment before using the water to irrigate greens.



Hydra Lake Clear is a special formulation for lake weed control that removes slime, string algae and blanket weed in lakes or other large bodies of water. It is a favoured product of various ground keepers including those taking care of fishing lakes, stately homes, golf courses, leisure parks, angling clubs and boat docks.

What quantity would be sufficient to treat a small lake, 80 x 50metres, 30cm deep? Thanks Ben


  • Posted by Simon Reid on Wednesday, 2 July 2014

    According to the dimension provided, area of your lake is approximately 4000sq.m.
    So, 25kg-50kg Hydra Lake Clear would be sufficient to treat your pond.

Is the water treated with Hydra Lake Clear safe for birds, fish and visiting animals?


  • Posted by Aj Edgar on Wednesday, 4 December 2013

    Yes, Hydra Lake Clear treatment is safe on fish, reptiles, birds, mammals, animals and water plants. However, use the treated water for irrigation purposes after five days of product application.

How many days does Hydra Lake Clear take to show any visible effect on the blanket weed?


  • Posted by Aj Edgar on Tuesday, 3 December 2013

    Unlike the traditional barley straw method to remove blanket weed, Hydra Lake Clear works instantly on the blanket weed causing it to die and float free on the water surface. Free floating blanket weed could be easily removed manually or left to sink and decompose at the bottom of the lake.

Posted by on Monday, 2 December 2013


Is it safe to use Hydra Lake Clear repeatedly, as blanket weed is a known to reappear even after treatment?


  • Posted by Aj Edgar on Monday, 2 December 2013

    Components of Hydra Lake Clear include natural minerals and sequestrates that are completely bio degradable. Hydra Lake Clear is non toxic. Therefore it is safe to use the product frequently. Once the blanket weed disappears you can continue with the low monthly maintenance dose to prevent re-appearance of blanket weed. Please follow the instruction for dosage rate. It is important to calculate the correct product amount required for treatment according to the expanse of the water body.

Great product!
Hydra Lake Clear is nothing but a great product. We tried it on my cousin's fish sanctuary and were speechless in days. We couldn't believe in our own eyes how it can rapidly removed all slime in just few days.
Review by Matt
Safe and effective!
This product is priceless. I never thought that for under £200 I would be able to clean my whole swan lake in no time.
Review by Imogen
So fast and so perfect!
I can say I'm an expert when it comes to pond supplies since I have been in the business for years. This is why I can say Hydra Lake Clear is very impressive. I've never seen a product work so fast, especially in removing blanket weed from my large pond.
Review by Alice
Delighted with the results
As a committee member of an Angling club in the North East, Blanket weed was becoming quite a problem around the edges of our lake. After speaking to Hydra and getting some slid advice from Steve, we decided to give this treatment a go and have been delighted with the results.
Review by Karen Kyme
Great product.
Great product. Keeping the water system in our golf course away from disgusting blanket weeds is critical to the club. Having it clean every month would cost us a lot of time and money. With Hydra Lake clear, however, cleaning it became so easy low-maintenance.
