*Based on average UK pool (4m x 8m), current energy rates (£0.24/kWh), water rates (£3.15/1000L), and 6-month swimming season. Individual results vary – see detailed assumptions below.

🔬 The Algae Problem Every Pool Owner Faces

Does this sound familiar?

❌ Green water appearing just days after shocking your pool
❌ Constant chemical battles that never seem to end
❌ Slippery surfaces around the pool edges
❌ Cloudy water that won’t clear no matter what you try
❌ Embarrassment when guests arrive and your pool looks swampy
❌ Filter blockages requiring frequent cleaning
❌ £300-500+ spent annually on shock treatments and algaecides

The root cause? Sunlight penetrating your pool water, triggering photosynthesis that feeds algae growth. Standard clear solar covers actually make this worse by allowing UV rays to pass through.

✅ The Energy Guard Solution: Selective Transmission Technology

The Energy Guard 500M uses groundbreaking selective transmission design with a dark grey top surface and black underside that:

Blocks Algae-Causing Light

🛡️ Prevents photosynthesis by blocking the specific UV wavelengths algae need to grow
🛡️ Maintains crystal-clear water even without chemical treatment
🛡️ Scientifically proven in 10-week university testing with zero algae growth

While Still Heating Your Pool

🔥 Absorbs solar energy through the dark grey surface
🔥 Transfers heat directly into water beneath the cover
🔥 Raises temperature up to 4°C through solar gain
🔥 Retains 98% of heat overnight through 500M GeoBubble insulation

How Is This Possible?

Traditional covers are either:

• Clear (heat well but feed algae) OR
• Opaque (block algae but block heat too)

Energy Guard’s patent-pending selective transmission uses a specially engineered dark grey colour that absorbs infrared (heat) wavelengths while blocking visible light (algae food). It’s the best of both worlds.

❓ Frequently Asked Questions

Does this really stop algae without chemicals?

Yes. The scientific testing is conclusive—the Energy Guard’s opaque design physically blocks the light wavelengths algae need for photosynthesis. You’ll still need baseline chlorine for sanitation, but you can reduce chemical usage by up to 70% because you’re preventing algae growth rather than constantly fighting it.

How can a dark cover still heat the pool?

The dark grey surface absorbs infrared radiation (heat) from the sun and transfers it directly into the water beneath. While it doesn’t transmit UV rays like clear covers do, the heat absorption properties are excellent. University testing showed 4°C temperature gains, plus the 500M thickness retains heat far better than thinner clear covers.

Will this work with my pool shape and size?

This specific listing is for a 17ft x 33ft rectangular cover. If your pool is a different size or shape, Parts4Tubs offers custom made-to-order Energy Guard covers. Use their solar cover calculator or contact their team for perfect-fit options.

How long does it take to pay for itself?

For a typical UK pool with a heat pump:

• Cover cost: £400-600 (depending on size)
• Annual savings: £700-900+
• Payback period: 6-9 months

After the first season, it’s pure savings every year for 6-8 years of cover life.

Can I use this with my pool roller/reel?

Absolutely. The Energy Guard 500M is designed for use with standard pool roller systems. The 500-micron thickness provides durability without being too heavy or rigid to handle. Many customers find it easier to manage than thicker 600M options.

Do the bubbles go up or down?

Bubbles face down into the water. This allows the heated air trapped in the GeoBubble chambers to transfer heat directly into the pool water. The dark grey surface faces up to absorb solar energy.

How does this compare to the 600M Gold GeoBubble?

Energy Guard 500M:

• Best for: Algae problems + good heat retention
• Thickness: 500 microns
• Focus: Selective transmission blocks algae light
• Heat gain: Up to +4°C
• Best in: UK climate with moderate sun

600M Gold GeoBubble:

• Best for: Maximum heat retention (no algae control)
• Thickness: 600 microns (20% thicker)
• Focus: Premium insulation + aluminum backing
• Heat retention: 75% heat loss reduction
• Best in: Cooler climates or maximum efficiency needs

Choose Energy Guard if algae is your primary concern. Choose 600M Gold if pure heat retention matters most.

Can I leave it on while the pump runs?

Yes. You can and should run your filtration system with the cover on. The cover won’t interfere with water circulation through your skimmers and returns. This is especially beneficial with the Energy Guard—reduced filtration time (up to 50% less) saves electricity while the cover prevents debris entry.

What about winter use?

The Energy Guard is designed for summer/swimming season use (April-October in UK). When closing your pool for winter, remove and store the cover carefully, then use a purpose-made winter cover. This extends the Energy Guard’s lifespan and ensures proper winter pool protection.

How do I care for and store the cover?

During use:

• Remove debris with a soft brush or leaf blower
• Avoid dragging across rough surfaces
• Keep pool chemistry balanced (TDS within SPATA standards)
• Don’t exceed 29°C water temperature

Storage:

• Clean and dry thoroughly before storage
• Roll loosely (don’t fold tightly)
• Store in a cool, dry location out of direct sunlight
• Use a storage bag if available

Proper care ensures you get the full 6-8 year lifespan.

💡 How to Maximize Your Savings

Best Practices for Energy Guard Use:

1. Cover every night – This is when 70% of heat loss occurs. Covering consistently maintains temperature with minimal heater use.
2. Use with a heat pump – Heat pumps are 3-5x more efficient than gas/electric heaters. Combined with the Energy Guard, you create an ultra-efficient system.
3. Consider a roller system – Makes covering/uncovering effortless, ensuring you actually use it daily. Costs £150-400 but increases cover usage by 80%+.
4. Test chemistry weekly, not daily – With algae growth inhibited and evaporation reduced, your chemistry stays stable longer. Reduce testing and chemical additions.
5. Cut filtration by 50% – Monitor water quality while gradually reducing pump run time. Most users reach 4 hours/day filtration with excellent clarity.
6. Remove debris promptly – A soft brush or leaf blower keeps the surface clean, extending cover life and maintaining algae-blocking effectiveness.
7. Monitor water temperature – Keep below 29°C to maintain warranty coverage. The Energy Guard retains heat so well that you may need to uncover briefly on very hot days.
