🔥 How the Blue 400M GeoBubble Cover Works

This isn’t just bubble wrap for your pool – it’s engineered thermal protection.

The GeoBubble Technology Advantage

Traditional bubble covers fail quickly because standard round bubbles have weak stress points. GeoBubble technology uses a patented interconnected bubble design that:

✅ Lasts 25% longer than conventional bubble covers (4-year warranty vs. typical 2-3 years)
✅ Distributes stress evenly across the entire surface, preventing premature failure
✅ Resists UV damage better than standard materials
✅ Maintains insulation properties throughout its lifespan

400-Micron Thickness: The Smart Middle Ground

The 400M thickness strikes the perfect balance between:

Heat Retention → Air-filled bubbles create an insulating barrier that traps warmth in your pool water
Solar Transmission → Blue tint allows beneficial UV rays through while blocking algae-promoting light wavelengths
Durability → Thick enough to resist tears and UV degradation, light enough for easy handling
Cost-Effectiveness → Budget-friendly price point with professional-grade performance

How It Saves You Money Daily

During the Day:

1. Sunlight passes through the blue material, warming the water by up to 3-5°C* in good conditions
2. Air bubbles trap heated air against the water surface
3. Blue tint filters out excessive light that promotes algae growth

At Night:

1. Insulating air bubbles prevent heat from escaping into cooler night air
2. Cover acts as a physical barrier against wind-accelerated cooling
3. Dramatically reduces evaporation (which causes up to 70% of heat loss in uncovered pools)

The Result: Your heating system runs 60-70% less frequently*, maintaining comfortable swimming temperatures while slashing energy consumption.

❓ Common Questions About This Cover

How quickly will I see savings?

Most pool owners notice reduced heating costs within the first month. Depending on your current heating expenses, typical payback periods range from 6-9 months*, after which all savings go directly back into your pocket.

Can I use this cover with my existing equipment?

Absolutely! This cover works perfectly with:

• ✅ Heat pumps (maximizes their efficiency)
• ✅ Solar heating systems (complements solar gains)
• ✅ Gas/oil heaters (reduces runtime significantly)
• ✅ Pool pumps and filters (safe to operate while covered)
• ✅ Manual roller systems (lightweight 400M thickness)

Will the blue colour affect heating performance?

The blue tint is strategically designed. It allows beneficial UV rays through to heat the water (gaining 3-5°C* in good conditions) while filtering out wavelengths that promote algae growth. You get solar heating benefits WITHOUT increased algae risk.

Is this thick enough for good results?

Yes! The 400M thickness provides excellent heat retention for UK conditions. While thicker covers (500M-600M) offer incrementally better insulation, the 400M delivers outstanding value – typically 65-75% of the performance at 55-60% of the cost.

When to consider thicker covers:

• Exposed locations with high winds (500M+)
• Pools that struggle to maintain temperature (500M-600M)
• Maximum possible heat retention needed (600M Gold)

How do bubbles facing DOWN work better?

The air trapped inside the bubbles gets heated by the sun. When bubbles face down, this heated air sits directly against the water surface, transferring heat efficiently through conduction. Bubbles facing up would create an air gap that reduces heat transfer effectiveness.

Can I leave it on while the pump runs?

Yes! As long as the cover is properly secured, your pool pump and filtration system work normally underneath. In fact, keeping the cover on during filtration maximizes heat retention and reduces evaporation even while circulating water.

How long does it really last?

With proper care (storing during winter, avoiding harsh chemicals on the cover surface, using a roller for removal), expect 4-6 years of reliable performance. The 4-year warranty reflects GeoBubble’s superior durability compared to standard 2-3 year cover lifespans.

What’s the installation process?

Simple!

1. Unroll the cover across your pool surface
2. Position bubbles facing DOWN into the water
3. Trim if needed for exact fit (though made-to-order sizing should be precise)
4. Optional: Attach to a manual roller system for easier handling

No special tools or professional installation required.

Will this fit my pool exactly?

This is a made-to-order product manufactured specifically to 16ft x 32ft dimensions. For best results, measure your pool’s waterline dimensions (not the outer edge) and allow for a slight overlap onto the pool surround for complete coverage.

Non-standard size? Parts4Tubs offers bespoke sizing – use their solar cover calculator to get exact measurements.

What about winter use?

Solar covers are designed for swimming season (typically May-September in the UK). When closing your pool for winter:

• Remove and store the solar cover in a dry, protected location
• Switch to a winter cover designed for harsh weather protection
• Proper storage ensures your solar cover remains in excellent condition for next season

This approach maximizes the lifespan of both cover types rather than forcing one cover to do jobs it wasn’t designed for.

Does it prevent debris completely?

While this cover dramatically reduces debris (leaves, insects, pollen, dirt), it’s not a rigid safety cover. Light debris may collect on top but won’t enter the water. Simply sweep or hose off the cover surface before removal.

Important: This is NOT a safety cover and cannot support the weight of children or pets.

🌡️ Temperature & Comfort Benefits

Extend Your Swimming Season by 4-6 Weeks*

By maintaining water temperature more effectively:

• Start earlier in spring: Reach comfortable temperatures 2-3 weeks sooner
• Swim later in autumn: Retain warmth 2-3 weeks longer
• Comfortable morning swims: Water stays warm overnight instead of cooling 3-4°C

Consistent, Comfortable Water Temperature

Uncovered pools experience dramatic temperature swings:

• Day-to-night drops: 3-5°C cooling overnight
• Cloudy day impacts: 2-4°C cooler after overcast weather
• Windy day losses: 4-6°C on breezy days

With this cover: Water temperature stays consistent within 1-2°C, meaning:

• ✅ No shocking cold plunges in the morning
• ✅ Predictable comfort levels day after day
• ✅ Less “should I turn the heat up?” decision-making

Better Swimming Experience

• Cleaner water: Less debris means clearer, more inviting water
• Fewer chemicals needed: Reduced chlorine use means gentler on skin and eyes
• Stable pH levels: Less evaporation means fewer dramatic pH swings requiring adjustment

---

💡 Maximizing Your Cover’s Effectiveness

Best Practices for Maximum Savings

Do:

• ✅ Cover your pool every time you’re not swimming (even during the day if unused)
• ✅ Use a roller system for effortless daily deployment (makes consistency easier)
• ✅ Keep the cover surface clean (hose off debris weekly)
• ✅ Store properly during winter in a dry, protected location
• ✅ Combine with a heat pump for optimal efficiency (saves up to 7,000 kWh annually*)
• ✅ Ensure proper fit – cover should rest on water surface, not stretched tight

Don’t:

• ❌ Leave cover off “just for a few hours” (you’d lose 3-4 hours of retained heat)
• ❌ Walk on the cover (not designed to support weight)
• ❌ Allow sharp objects to contact the surface
• ❌ Use harsh chemical cleaners on the cover material
• ❌ Leave bunched up in direct sunlight when stored

Complementary Investments for Even Greater Savings

Manual Roller System (£80-150): Makes daily deployment effortless – covers/uncovers pool in 60 seconds instead of 10+ minutes. This convenience dramatically increases consistency of use (and therefore savings).

Heat Pump (if you don’t have one): The combination of a solar cover + modern heat pump delivers the most cost-effective pool heating available. Together they can reduce heating costs by 75-85% compared to uncovered pools with gas/oil heaters.

Pool Thermometer (£10-25): Track your water temperature to see exactly how much the cover is working. Many pool owners are amazed to discover 3-4°C gains on sunny days.
