Healthy Ponds AquaSphere PRO Biodegradable Water Treatment — 500,000 Gallons

Healthy Ponds AquaSphere® PRO Biodegradable Water Treatment is an all-natural dispensing system made from a corn-based resin that introduces beneficial bacteria into the water, reducing excess nutrients and breaking down organic matter that clouds water. This sphere will treat areas containing up to 500,000 gallons of water. It's important to use the correct treatment size for your specific water feature. To calculate the size of your pond, take: Length x Width x Average Depth x 7.5 = Total Gallons. You cannot over treat water, but under treating may not yield desired results.
