Pond Water Renewal and Maintenance, 32 oz for Medium Established Ponds Supernatural ReNew provides regular biological support to keep established ponds in good balance through the season. The 32 oz bottle covers ponds up to 1,000 gal (3,800 L) through a full season of biweekly maintenance, making it the practical size for most residential koi and ornamental ponds that are already performing well and need ongoing support rather than active treatment. Right-Sized for Regular Maintenance ReNew works as a steady biological top-up rather than a correction product. The 32 oz bottle provides enough for a full season of treatment at biweekly intervals for a 1,000 gal (3,800 L) pond, or a full season of weekly treatment for a 500 gal (1,900 L) system. Having a full bottle at the start of the season means consistent, uninterrupted maintenance without mid-season restocking.

Ideal for ornamental ponds and koi features from 500 to 1,000 gal (1,900 to 3,800 L) in good biological health that need consistent seasonal maintenance rather than active corrective treatment.
