Do you dream of having a healthy pond? Yes!

The most common problem for an unhealthy pond is, ‘Organic Silt deposition’ which is fairly unavoidable in most water bodies including ponds. Organic silt or sludge build ups are a result of organic matter (fish excreta, fish food, fallen leaves, etc.) that sinks down.

Cost effective and eliminates;

  • Waste products of plants.
  • Uneaten fish food.
  • Dead algae.
  • Excess nutrients.

Hydra Silt-less All-in-One is a natural solution to your pond related problems!

It is an excellent product to decrease organic deposits levels in your pond. It is an effective pond organic silt remover, eliminates bad odour, mud, cloudy water and enhances water clarity. The beneficial bacteria present in Hydra Silt-Less All-in-One promote aerobic activity and reduce the production of toxic gases such as methane and hydrogen sulphide. As a result, you can see a reduction of the smelly organic silt layer!

It’s a safe and ideal solution to reduce sludge from ponds with a high number of fish!

It acts as a source of calcium, essential for plants and aquatic animals. The calcium carbonate base enhances water quality by clumping suspended solid particles causing them to settle down. The alkaline property of the base balances out the pH level of the water by neutralising the acid in organic silt and water.

Yes! net over your pond to trap leaves and removing blanket weed from the surface will also help! but if you don't fancy vacuuming out the bottom of your pond the aerobic bacteria in Hydra Silt-less All-in-One will decrease organic silt-levels by stimulating micro-organisms to break down the waste organic matter.

Good results

I was recommended this product which gave good results. I applied the treatment and within a few days I could see visibility within my pond. Further on from those days it was very clear. Will definitely buy again.

This product is for real

This is a really good product. I needed to rectify the residue that was left from another treatment to my pond. I had tried other brands that failed. I researched this product that had great reviews and I too was successful with the use.

Game changer

This product really is a game changer. Hydra products are excellent and have saved my pond. My once pea soup pond is now beautifully clear and free from silt, sludge and I once again have happy fish.
