We’re constantly being asked – Will Envii Pond Klear work on a pond without a filter?

The short answer is that it does work on ponds without filters.

Here’s the longer answer…

The bacteria in Pond Klear eat the organic matter (i.e. twigs, bird poo, fish food etc) that decays causing algae and sludge. However, it would be a tall order for them to eat all of the algae and sludge created so they also detach it from any surfaces and clump it together allowing it to be caught in the filter.

So Pond Klear WILL work in a pond without a filter but it won’t work anywhere near as quickly.

Because of this we generally recommend that people use Pond Klear Xtra and Sludge Klear in a pond without a filter. These products together have a far higher concentration of bacteria and work in tandem to eat the organic matter. While it is more expensive, you are guaranteed results.

It’s also worth physically cleaning your pond as best you can by removing anything from the surface. This will give the bacteria less to do and make it work quicker.
