API Pondcare Ecofix Sludge Destroyer Bacterial Pond Cleaner

API® Pond Ecofix Sludge Destroyer is an all-natural bacterial cleaner that reduces pond maintenance by breaking down fish waste, dead algae, and organic debris that settle at the bottom of your pond. Live bacteria continuously work in warm water to clear sludge, improve water clarity, and reduce odors — without harming your fish, plants, or biological filter.

Available in three sizes for any pond:

• 16 oz — small to medium ponds, spot treatment
• 64 oz — mid-size ponds, season-long use
• 1 Gallon — large ponds, best value per ounce

Use API for a clean, healthy pond all season long!
