POND BOSS Waterfall Spillway

Easy installation makes it simple to add a waterfall or a disappearing water feature to an existing pond. The spillway is designed for smooth flow and quiet operation, connecting to a pump rated between 800 GPH and 2500 GPH. A built-in water baffle and 8-inch wide spillway ensure a gentle, visually appealing display. UV-resistant, durable plastic construction provides long-term performance and stability in outdoor settings.
MICROBE-LIFT AUTPREP Autumn and Winter Prep

This two-part system (liquid plus dry packets) is designed to winterize ponds and support healthy fish through colder months. It helps maintain a balanced internal pond environment and accelerates debris breakdown, contributing to a clearer, healthier winter habitat for koi, plants, and decor. By preparing the pond for spring startup, it supports reliable restart and ongoing water quality during off-season periods.
CrystalClear Spring & Fall Prep

These pre-measured water-soluble packets supply natural bacteria and barley to replenish winter losses and aid spring startup. The formula accelerates the decomposition of leaves, twigs, and sediment throughout winter, helping maintain water clarity and a healthier pond ecosystem for returning aquatic life in the new season.
The Pond Guy Seasonal Defense

This 12-pack delivers a combination of beneficial bacteria and barley enzymes designed for cooler temperatures. It accelerates the breakdown of leaves, scum, and sediment that create pond muck, while barley helps keep water clear. The product is intended for autumn, winter, and spring when pond temperatures fall below 50°F, and treats up to a 1,000-gallon pond per packet.
Blue Ridge Koi Fish Food 5lb

These cool-season, wheat-germ-based floating pellets are designed for koi and goldfish when water temperatures drop below 60°F. The pellets are easily digestible, reducing waste and supporting healthy growth during spring and fall transitions. They provide a practical nutrition option for ponds with koi or goldfish in cooler months.
Buying Guide
Key considerations when choosing waterfall-related products and seasonal pond care items:
- Water flow and compatibility: Match spillways and pumps to pond size. A spillway with an 800–2500 GPH range pairs well with mid-sized ponds for a steady waterfall effect.
- Seasonal maintenance needs: For temperate climates, prioritize products that support winterization, spring startup, and year-round clarity, such as autumn/winter prep and spring/fall bacteria blends.
- Water clarity and filtration: Combine natural bacteria with barley or other clarifiers to reduce leaves and sediment buildup and maintain clear water during seasonal transitions.
- Fish health and nutrition: In cooler months, select foods and supplements that are easily digestible and suited to low temperatures to support koi and goldfish without overloading the system.
- Ease of installation and durability: Look for UV-resistant, durable plastics and straightforward installation steps to minimize ongoing maintenance and maximize longevity.
- Combination use: Many ponds benefit from a mix of a waterfall component (for aeration and aesthetics) plus seasonal treatments to sustain water quality across seasons.
Consider your pond’s volume, fish load, and local climate when integrating these products. The right combination can improve sound and visual appeal from a waterfall while maintaining a healthy pond ecosystem year-round.
