Algae growth uses oxygen and causes the generation of a stagnant body of water. Stagnation changes the balance of life within a pond or lake resulting in the die off or movement of the local ecology to more favourable areas. Stagnant areas are also the preferred breeding grounds for pests such as mosquitoes.

“Competition keeps the algal growth in check and enables

the system to remain naturally balanced

and oxygenated via photosynthesis.”

Once oxygen has been depleted, biomass within the water body will begin to be anaerobically degraded by specialist microorganism. One such class of microorganisms are the sulphate reducing bacteria which breathe sulphate instead of oxygen, and produce sulphide instead of carbon dioxide.

Sulphide – which is perceived as a rotten egg smell by humans – is particularly unpleasant and can be detected at very low levels by the receptors of the nose. And as sulphate is present in most groundwaters within the UK, the probability of the generation of sulphide gas from stagnant water bodies is high. Further, this anaerobic microbial action can also turn the pea soup into an unsightly murky black/brown as dying algal biomass is degraded.

A common method of tackling odour issues is through aeration, whereby a piece of equipment such as a fountain causes movement of the water to enable a greater contact with the air. This method, although capable of impacting the growth of algae and tackling sulphate-reducing bacteria, might not be able to adequately or cost-effectively service an entire body of water. Using our expertise in bioscience, we have developed innovative complementary solutions

which can help improve water quality and keep it clearer and smelling fresher for longer.

Genesis Biosciences provides biological products containing stable, environmentally friendly and safe bacteria, which are capable of growing in a range of different environments from ponds to wastewater treatment facilities. These bacteria, combined with our unique eco-beniyn chemistry, deliver an effective treatment option which  aesthetics and the local ecology.

The aim of using biological products in this instance would be to outcompete the problematic algae and sulphate- reducing bacteria for nutrients and impact their growth through the production of antimicrobial compounds. By adding additional bacterial cells to a system, the available nitrogen and phosphorous has to be shared amongst the actively growing population. As the Bacillus microbes within our products can be supplemented in large numbers and have very fast growth rates, much less food is therefore available for algal growth. This competition keeps the algal growth in check and enables the system to remain naturally balanced and oxygenated via photosynthesis.

As well as outcompeting algae, the supplementation of additional Bacillus—which expands the metabolic potential of the system—will decrease the substrates available for sulphate reduction. This coupled with the production of antimicrobial

compounds keeps the generation of odours to a minimum.

Through their colonisation of the system our blend of Bacillus is able to reduce sludge and combat turbidity issues, keeping the water clear and sparkling for longer.

Dosing these products is easy and safe, with our biological products able to be dosed directly into water bodies. Pre-emptive dosing creates a robust system able to greater withstand and buffer a system against nutrient loading, thus preventing the occurrence of algal blooming.

Naturally, such products aren’t purely  but also facilities across the leisure industry at large. With ornamental and recreational ponds and lakes often valuable aesthetic features utilised by hotels, spas and luxury restaurants across the entirety of the UK, biological products like our Evogen Pond Maintain and Evogen Clarity have the potential to put the issue of retaining crystal clear waters to bed for good.

Whether it’s lucky pennies at the bottom of a fountain or irretrievable balls resulting from unlucky shots, the ability to see the contents at the bottom of your water feature shouldn’t be a hope, but an expectation.
