Aquapill WinterPill Pool Winterizer for up to 30,000 Gallons — 6-Month Slow-Release, Scale & Stain Protection

Keep your pool low-maintenance through the cold months with a single floating capsule engineered to gradually dispense a four-part formula. WinterPill combines scale and stain inhibitors with enzyme boosters to limit buildup, minimize scum lines, and help preserve clear water under a winter cover. Its floating design and simple pierce-and-place activation make it compatible with all pool types and filtration systems.

How do I activate and place the WinterPill?

Activation is a two-step pierce process using the included blue tool and white push-pin. After shaking the capsule, use the blue tool to open the cap, then pierce a single dot with the white push-pin and place the pill in the skimmer or over the water so it can float freely.

• Shake the capsule before use to mix contents.
• Use blue tool to break the cap, then pierce one dot with the white push-pin.
• Place the pill where it can float under the cover or in the skimmer if directed.
• One pill remains active up to six months; discard and replace in spring.

What does the WinterPill protect against during winter?

The formula addresses common winter issues without daily attention. It helps reduce scale formation and surface staining, keeps organic debris from causing cloudiness, and minimizes scum lines along the waterline.

• Scale inhibitor reduces mineral deposits on surfaces and equipment.
• Stain inhibitor guards vinyl, plaster, and tile from discoloration.
• Enzyme enhancement breaks down organic contaminants that cause cloudiness.
• Slow-release action maintains consistent dosing for months.

How many WinterPills do I need for my pool size?

One WinterPill treats pools up to 30,000 gallons; for larger pools, simply add additional pills proportionally. Use one pill per 1,000 square feet of surface area if covering area is your measurement basis rather than volume.

• Up to 30,000 gallons — one pill per pool.
• Larger pools — add one pill for each additional 30,000 gallons or per 1,000 sq. ft. of cover area.
• Position pills so they float freely for even distribution.

Will WinterPill work with my pool equipment and cover?

WinterPill is formulated to be safe with all common pool filters and surfaces when used as directed. It’s intended for use with winter and safety covers and won’t interfere with normal filtration systems while releasing its active ingredients slowly.

• Compatible with sand, cartridge, and DE filters.
• Safe for vinyl, plaster, fiberglass, and tile when used per instructions.
• Designed to float beneath winter covers for continuous dosing.
• Removes easily in spring; discard as household waste and follow spring treatment recommendations.

Who is this for? Aquapill WinterPill is aimed at pool owners who want a low-effort winterizing solution that reduces spring cleanup. It suits homeowners with in-ground or above-ground pools, those using winter or safety covers, and anyone seeking to limit stains, scale, and organic build-up over the off-season. For spring reopening, replace WinterPill with Aquapill 2 Clarifier Plus (AP02) to resume regular maintenance and water clarity.
