The Problem

Spring sunshine is a welcome change in the weather, but with the onset of warm weather, your clear pond may become green due to unsightly algal growth. The nutrient build up over the winter months, actively feeding fish in warm weather and sun rays penetrating the pond surface create suitable conditions for phytoplankton to thrive.

Phytoplankton or single celled algae, make the clear pond water turn green or like pea soup.

Algal blooms are not only visually unappealing, but excessive algae also compete with fish and other aquatic creatures for dissolved oxygen during the night.

On cloudy days when single-celled algae are unable to replenish oxygen with photosynthesis, depleted oxygen levels prove harmful to the fish and other water plants.

The Solution:

How to Get rid of Green Water

Hydra Crystal is a unique mineral-based formulation that acts fast on the algal cells causing them to cluster together and descend to the bottom of the pond where it could be picked up by the pond filters. It is important to have the filters running and regularly cleaned during the treatment.

Hydra Crystal used in combination with Bio Aquatic Boostkeeps the single-celled algae from returning. Hydra Bio Aquatic Boost is a blend of favourable bacteria that feeds on excess nutrients (on which algae survive) and thwarts algae growth.

Green water treatment
Monday, 5 August 2019  | 

On my first application of hydra clear green water treatment I seen a slight difference but not enough, after 24 hours tried again with a 10% water change still the same, so onvwaiting 2 days thoughtvid try again but had changed my filter sponges around 1st then instead of pouring the solution onto the pump put it all over the water including my water fall where there is a little pool at the bottom, to my surprise within 5 mins my small water fall pool was clear and after 20 mins my pond was still particles floating but I can actually see my fish even the writing on my pond pump, very happy now I will be buying this product again to keep on top of my pond water and will advertise this product and company , very happy fish mum,👍🏼👍🏼👍🏼👍🏼

Hydra Crystal (Green Water Treatment)
Saturday, 1 June 2019  | 

I recently (May) visited my relation in Cornwall and the pond I had renovated in December was totally green and they couldn't see their fish. I purchased this product and I had a phone call yesterday (2 weeks later) and they were over the moon as they can now see their fish swimming around at the bottom of their fish pond.
I have been using Hydra blanket weed products for the past few years and they are excellent.
