The cold-weather difference
Why a cold-water formula matters
Most pond treatments slow down or stop working as the water cools, leaving muck to build up all winter. This fall and winter formula is built to keep going.
Common approach
Stopping treatment in fall
- Standard formulas slow down as water temperatures drop
- Organic matter and sludge accumulate through the cooler months
- Ponds start spring dirtier and out of balance
- Buildup left to accumulate rather than being actively digested
