Why Do Ponds Go Green In The Spring?

28th October

Ponds turn green in early spring. That’s pretty much gospel among pond keepers; it’s just the way things are.

Why does it happen?

Basically, there are two types of bacteria in a pond – aerobic (good) and anaerobic (bad).  These two types of bacteria are in a constant battle to digest the organic debris that ends up in the pond (twigs, leaves, fish food etc). When the anaerobic (bad) bacteria digests it, it takes a lot longer and produces gases like nitrogen and phosphorus which, in turn, act as a food source for algae. When we add aerobic (good) bacteria to the pond, they overcome to the anaerobic (bad) bacteria and digest the organic debris a lot quicker and don’t create any harmful gases. This is why, when you use bacterial pond treatments you are getting to the source of the problem; rather than just eating the algae, you are starving it of its food source.

The problem is that anaerobic (bad) bacteria can digest organic matter as low as 6°C, whereas aerobic (good) bacteria treatments traditionally work around 10-12°C. This means that all winter your pond is losing the battle against algae and when spring comes, the algae starts to feed.

It’s all about to change

Envii Winter Pond Treatment is a new type of aerobic bacteria treatment.  It works as low as 4°C which means that you can win the battle of the bacteria all year round.  Its task-specific bacteria digest the organic debris meaning that when you come back to pond in spring, it will stay clear. Then continue to treat with Envii Pond Klear and your pond will never go green again!

This is the first pond treatment designed to work all through the winter!
