API Stock Tank De-Icer

The API Stock Tank De-Icer is a practical solution for keeping water from freezing in cold climates.

A 6-foot anti-rub power cord helps prevent wear and accidental damage to the cord during use.
De-icers are essential for livestock water accessibility during freezing weather. This model provides reliable surface heating to maintain liquid water, reducing the risk of ice blockages that can impede drinking and force animals to seek less desirable alternative water sources. It’s particularly suitable for larger tanks and higher-capacity setups where maintaining water availability is critical.
Consider this option if you live in areas with frequent freezing temperatures or require a robust, commercially available de-icer to supplement stock tanks and troughs. It complements large tanks while providing a safety net against ice hazards.
Buying Guide
Key purchase considerations when selecting a 3-foot tall stock tank or related livestock troughs and accessories include:
- Capacity and livestock needs: Choose a size that accommodates your herd size, watering cycles, and maintenance routines without excessive weight or bulk.
- Durability and material: Structural foam and rigidcell designs offer long-term durability in weather exposure. Polyethylene tanks are lighter and portable but may scratch or warp with rough use.
- Warranty and manufacturing location: A longer warranty and domestically produced products may indicate better support and build quality; consider your tolerance for maintenance costs and replacement timelines.
- Multipurpose use: If you plan to repurpose tanks for pools, washes, or DIY projects, assess containment shape, handling ergonomics, and compatibility with accessories like de-icers and heaters.
- Weather and climate considerations: In freezing climates, pairing a de-icer with a large tank helps prevent ice blockages, while insulated lids or covers can reduce heat loss.
- Ease of cleaning and maintenance: Rounded interiors, smooth surfaces, and accessible drainer features ease routine cleaning and minimize biofilm buildup.
- Portability vs. permanence: Lighter plastic or foam tanks are easier to move, whereas heavier steel-reinforced or rigidcell tanks offer greater long-term stability.
- Installation and setup: Ensure the chosen tank fits your space, access to water supply, and compatibility with hoses or trough stands if needed.
From a durability perspective, Rubbermaid’s 100-, 150-, and 300-gallon stock tanks provide consistent performance with USA-made quality and a robust warranty, suitable for farms of varying sizes. For smaller operations or portable needs, the Little Giant oval stock tank adds ergonomic benefits and ease of handling. In colder regions, the API de-icer complements larger tanks by maintaining water access during freezing weather. When evaluating options, consider not only the tank’s capacity but also how you will maintain animals’ drinking water, manage cleaning tasks, and plan for seasonal changes.
