Small Pond Biodegradable Biosphere Pro For Ponds From 6,000 to 50,000 Gallons

These changed

These used to come with string for attachment. No string any more. We liked being able to keep the raccoons from taking the ball out of the pond. That's harder to do without the string.

Continuously working

Put it in last week after cold MT winter and is already has at least half of the algae from the surface of the pond.

Working extremely well! Very pleased!
