Frequently Asked Questions (FAQs)

1. How do you keep wildlife pond water clear?

During hot calm days where the water's still and warm from the sun, you can try breaking the surface with a brief spray of a hose, to disturb and aerate the water a little. Introducing plants like waterlillies, which have floating leaves, can also help, by reducing the amount of sunlight the algae can get.
