Treat your natural pond to a green water treatment!

So, you either decided you wanted a pond but didn’t want an expensive pump or filtration system, or you have moved in to a house and inherited a pond that doesn’t have a pump or filtration system. Either way, you’ve now got a hole with dirty water and algae and you’re sick of the sight of it.

Good News! You’ve come to the right place to create a healthy pond.

How to keep pond water clean without a filter

Envii Natural Pond Klear contains billions of beneficial bacteria whose job is to give your pond that well needed makeover. The innovative bacteria will concentrate on digesting unwanted organics in your pond that act as a food source for algae. By eliminating these organics, Envii Natural Pond Klear will clear green, murky water and starve algae of its food source.

Capable of working down to 4°C, the bacteria in our green water treatment improves the clarity of your water and the quality. By creating biologically balanced water, it provides the perfect water conditions for the fish in your pond. As a result, your fish can now enjoy their new, clean home and you can have peace of mind that they are safe.

If you’re a keen gardener and have a natural pond, keep it habitable and encourage frogs to live in it. Frogs are a great, natural way of protecting plants by killing slugs and snails. So, by using this natural pond algae treatment you are killing two slugs with one stone!

How to get rid of blanket weed

If you have algae that is floating on top of your pond, you have blanket weed. Whilst our Envii Natural Pond Klear will eliminate this by starving it, Envii Blanketweed Klear is a quicker way of getting rid! Learn more in our guide on how to get rid of blanket weed here.

If the algae is submerged and looks like string, or hair, you’ll need Envii Algae Klear Xtra to kill it quickly.
