Gen2 EnergyGuard™ cover edge on pool water
Patented Selective Transmission

Uses the sunlight you want.
Blocks the light algae needs.

Not all sunlight works the same way. EnergyGuard’s midnight-blue material lets warming near-infrared light pass through to your pool while absorbing much of the visible light algae need to grow. It’s a smarter way to use the sun for warmer water and less algae.

How It Compares

Not all bubbles are created equal.

If your last solar cover turned brittle or began falling apart after a season or two, traditional round bubbles may be part of the reason. Their shape concentrates stress at vulnerable points, while the patented GeoBubble™ design distributes stress more evenly across the material.

2026 Pool Testing

Three identical pools. One clear result.

In a 70-day outdoor trial, Plastipack tested three identical 11,000-gallon pools side by side: one with Gen2 EnergyGuard™, one with the original EnergyGuard™, and one uncovered. No heaters, just the sun.

The results? Warmer water, even through cooler weather, and less than half the chlorine needed for the uncovered pool.

Answers Before You Ask

You've got questions. We've got answers.

What does graphene actually do in the cover?
Graphene nanoplatelets are blended through the polymer itself, reinforcing the material from within. The result is 51% higher puncture resistance and 24% higher tear resistance than the original 20-mil EnergyGuard™, from a lighter 16-mil that uses 20% less polymer, and is easier to roll, fold, and handle every day.
Why is Gen2 16 mil if the original EnergyGuard™ was 20 mil?
Gen2’s graphene-enhanced film is reinforced from within, so it uses 20% less polymer yet matches or exceeds the strength of a conventional 20-mil cover. In university tensile, tear and impact testing it showed 51% higher puncture resistance and 24% higher tear resistance than the original 20-mil EnergyGuard™, with the same 8-year expected lifespan, in a cover that’s lighter to handle and less prone to fold marks.
How much warmer will my pool get?
Gen2 EnergyGuard™ is engineered to raise water temperature by up to 12°F, while its insulating air cells hold the heat you've gained by stopping overnight evaporation loss.
Do I need a pool heater for this to work?
No. Sunlight alone warms your pool by up to 12°F. Have a heater? Gen2 EnergyGuard™ cuts that energy use by up to 60%, reducing your pool heating costs.
How does color affect performance?
Color is the performance. EnergyGuard's midnight-blue surface absorbs the visible light algae need to grow and converts it to warmth, while infrared sunlight passes straight through to heat your water. That's the patented Selective Transmission at work.
Can it extend my swim season?
Yes. Up to 12°F of solar gain plus overnight heat retention adds weeks of comfortable swimming on both ends of the season, without touching a heater.
Why does my pool lose all its heat overnight?
Evaporation is the number one cause of pool heat loss, responsible for up to 70% of it, and Gen2 EnergyGuard™ eliminates 98%+ of evaporation. The insulating air cells hold the day's warmth through the night, so you're not starting cold every morning.
Will this lower my water bill?
Yes. By eliminating 98%+ of evaporation, Gen2 EnergyGuard™ saved roughly 8,500 gallons of water a year on a 13 x 26 ft test pool in Plastipack's UK testing. Pools in hot, dry climates lose more water to evaporation, so they can save even more. That's why it carries the Smart Approved WaterMark.
Can it reduce how many chemicals I use?
Yes. Covered pools use up to 60% fewer chemicals. Less evaporation means treated water stays in the pool, and less debris and UV exposure mean your chemistry stays balanced longer.
Does it work on shaded pools?
Yes. Even in partial shade, evaporation is still your pool's biggest heat thief, and Gen2 EnergyGuard™ eliminates 98%+ of it while its insulating cells hold the warmth your pool does collect. You'll see less solar gain than a full-sun pool, but the retention benefits work in any light.
I'm in a hot climate. Is Gen2 EnergyGuard™ still the right cover?
Yes, for most pools. Hot, dry climates lose the most water to evaporation, and Gen2 EnergyGuard™ eliminates 98%+ of it, keeping water and treated chemicals in the pool. Its midnight-blue surface also absorbs the visible light algae need to grow, which matters most in the hottest weeks of the season, when algae blooms fastest. If you would rather keep your water cooler, look at GeoBubble™ CoolGuard™: its reflective glacial-blue top layer cuts daily solar heat gain by up to 55% while still stopping 98%+ of evaporation.
How long will it last, and how do I care for it?
GeoBubble™ covers are engineered for an 8+ year product life, 3–4× longer than a traditional pool cover.* Care is simple: keep it on the pool whenever you're not swimming, store it under the included reflective storage sheet when it's off, keep your water chemistry balanced, and never re-cover the pool right after a shock treatment. For effortless daily handling, add Rocky's Reel System.
Can I leave it on through the off-season?
Yes. EnergyGuard's light-filtering material is effective enough to stay on as a winter cover through the entire off-season, keeping algae in check while the pool is out of use. The material is rated to -13°F, so freezing temperatures won't crack or damage it.
How do I choose the right size?
Just measure your pool's widest and longest points and order the size that fills the entire area. Any excess trims easily for an exact fit.
What if I have an unusual pool shape?
No problem. Order for your widest and longest points, then trim the excess. Our custom-fitting video shows how easy it is.
Will it work with my existing reel?
In most cases, yes. GeoBubble™ covers roll onto standard solar cover reels, and the Floating Leading Edge trims to your exact width for a DIY fit on new or existing covers.
Is it safe for my pool type?
Gen2 EnergyGuard™ is suitable for chlorine & saltwater pools, in-ground or above-ground.
Is this a winter or safety cover?
GeoBubble™ covers are solar blankets, designed for warmth and efficiency. They are not safety covers and are never a substitute for a barrier, fence, or supervision.

Overall rating: 4.8 / 5 from 144 reviews.

Not terribly expensive, helps a lot to keep the pool warm, was easy to cut to size. Arrived promptly. It would be best on a reel, but it is light enough - though unwieldy- to fold in half and then fold again (and once more) to pull out of a rectangular pool with one person. This is not the purpose of the cover, but be forewarned, any debris (leaf litter, pinecones, etc.) will just sit on top and fall into the pool when you remove the cover. It’s definitely not meant for keeping the pool clean.

GeoBubble EnergyGuard™ Award-Winning Solar Pool Cover - The Best Cover For Heating While Inhibiting Algae

Customer video review of GeoBubble EnergyGuard™ Award-Winning Solar Pool Cover - The Best Cover For Heating While Inhibiting Algae

This is the best pool cover I could find. I have been through two different lighter and cheaper pool covers that have disintegrated in 2 to 3 years. My new cover is 20 mil thickness, and it shows! It lays flat as a board across my pool. I have a solar heater system, also from Solarpoolsupply.com, which gives some great pool temperatures despite 50 degree nights. My pool is 12x24 ft, 8000 gallons, and averages 3 to 4 degrees temperature loss during the evening in late October, but with sunny days, I can have pool temperatures close to 90 degrees! I use a reel to easily retract and install this cover. For what you pay to have, maintain and enjoy your pool, this cover is worth the price. I love this cover!

GeoBubble EnergyGuard™ Award-Winning Solar Pool Cover - The Best Cover For Heating While Inhibiting Algae

This solar cover is by far the best one we’ve had on our pool. It’s heavier than anything else we’ve bought. It keeps the water warm and keeps out debris. The customer service was great!! I had an issue with the cover and Zach took care of the problem. He was very prompt with his responses and fixed the issue satisfactorily. Thank you for making a great product and following through with fantastic customer service.

Customer photo review of GeoBubble EnergyGuard™ Award-Winning Solar Pool Cover - The Best Cover For Heating While Inhibiting Algae

We have a 17' Hydropool Self-Cleaning Swim Spa. After much consideration, we moved from an End2End Rolling cover to the Solar Pool Energy Bubble cover. 1-) the E2E, while providing good coverage for the entire spa, it trapped moisture causing the control panel to short out (2 in 4 years @ $2K a pop) and 2-) condensation collected in the cover, which just seemed unhealthy when it drained back into the spa. Our 2 concerns about the Energy Bubble, was 1-) if the cover would jam or causing the self-cleaning mechanism of this swim spa to malfunction: which as seen in the 2 attached photos, by securing both ends of the cover, has not been an issue, and 2-) how to manage the constant sun exposure of the rubber neck pads and spa walls...which we are still working on. So far we love the Energy Bubble cover, it has reduced our energy bill to keep the water at a perfect temprature and alot easier to manage than the bulky E2E cover. We are very happy and recommend the Energy Bubble to other swim spa owners.

Customer photo review of GeoBubble EnergyGuard™ Award-Winning Solar Pool Cover - The Best Cover For Heating While Inhibiting Algae

This is the strongest and most heat producing solar pool blanket I’ve ever had. Needed that in my retirement! There was enough extra over the dimension I purchased to have an extra strip to go under my diving board and leave the reel up against the end of the board for convenience. Don’t feel like I might tear it when I have to pull it out and put it on by myself. I can even do it from in the water in the middle of the deep end by myself!

GeoBubble EnergyGuard™ Award-Winning Solar Pool Cover - The Best Cover For Heating While Inhibiting Algae

Recently purchased this solar pool cover and so far, we're very pleased. We'd purchased some a few years ago from other companies but they were not long lived in the Arizona sun. It did work to keep the pool water warm but the small blue bubbles came off the backing and ended up making a huge mess. We purchased this one from Solar Pool Supply because it was thicker (20 mm) material, appears to be better made and the design is both different and unique. Am happy with our purchase.

GeoBubble EnergyGuard™ Award-Winning Solar Pool Cover - The Best Cover For Heating While Inhibiting Algae

i was very skeptical about spending so much on a cover for our little bestway pool from costco, but the cover we had on it last summer was so flimsy and annoying and was not a heating cover so i was desperate for anything better. i was honestly surprised at how much this heats our pool! granted our pool is only 3 feet deep so a deeper pool might not heat up as much from just the cover, but it definitely makes a huge difference for us! and i like how thick it is and that it floats on the water. i just wish they made a reel for the 12 foot round cover, as it is very cumbersome to take off and put back on due to the thickness. it's fairly impossible to actually "fold" very nicely when taking it off the pool. but we are ok dealing with that bc of the benefits!
