Calcium Doesn't Wait for You to Notice It
That chalky white line at your waterline started forming long before you saw it. Every day your pool water evaporates, minerals concentrate, and calcium looks for a surface to bond to. Scrubbing it off is a weekend. Keeping it from forming is four ounces a week.
Pool Hero is the treat step. Start with clean tile and surfaces, then Pool Hero maintains them for you, week after week.
Pool Hero — Weekly Water Treatment
PFAS-Free, Professional-Grade Formula
The Pool Hero System is a three-step calcium and mineral management system for pools and spas. It works in a simple sequence: Clean removes existing calcium deposits and scale, Protect seals surfaces with a nano-barrier so deposits can't bond, and Treat adds a weekly water treatment that prevents new buildup before it forms. Every product is PFAS-free, pH-neutral, and safe for all pool surfaces and sanitizer systems — giving you crystal-clear water and clean tile with far less scrubbing.
Add Pool Hero to your pool water each week — your simple, set-and-forget defense that:
- Prevents calcium and mineral deposits before they form
- Protects all pool surfaces, tile, and finishes
- Works with chlorine, salt, and other sanitizer systems
- Shields tile, equipment, and the waterline from scale
- Makes weekly upkeep simple — no complicated measuring
Dosage: Add to your pool water weekly per the label directions, based on your pool's volume.
Compatibility: Works with chlorine, salt, and other sanitizer systems — and it won't disrupt your pool's water chemistry.
PFAS-Free & Pro-Grade — trusted by pool professionals, safe for family and pets.

How to Use Pool Hero
Pool Hero is designed to be the easiest weekly pool treatment you will ever use. No complicated steps. Just pour and go.
Startup or Problem Water
If you are just getting started or dealing with active calcium issues, add 8 oz per 10,000 gallons directly to the pool with the pump running.
Weekly Maintenance
Once your water is conditioned, add 4 oz per 10,000 gallons once per week. Pour slowly around the perimeter of the pool. No pre-dilution needed.
That's It
Pool Hero quietly works in the background, keeping calcium suspended so it cannot harden into white scale on your tile, surfaces, and equipment.
Safe to Swim
You can swim 30 minutes after application.
The Pool Hero System, How It Works
Three steps. One complete solution. Zero guesswork.
STEP 1
CLEAN
HCR / HCRX+Si Heavy Calcium Releaser
Start with a clean slate. HCR and HCRX+Si dissolve and lift stubborn calcium deposits, mineral scale, and efflorescence from pool tile, coping, stone, and water features — without acid, without bead blasting, and without affecting your water chemistry. It works on even the heaviest buildup.
Acid-Free • Will Not Affect pH • Safe on Most Surfaces
STEP 2
PROTECT
Cal Block
Lock in your clean. Cal Block creates a nano-barrier on treated surfaces that blocks calcium and mineral deposits from bonding in the first place. Spray-on, wipe-off simplicity — and one application lasts all season.
Nano-Barrier Technology • Tile, Stone, Concrete and Pavers • 3 to 6 Month Protection
STEP 3
TREAT
Pool Hero / Spa Hero
Keep it clean all season. Pool Hero and Spa Hero are your weekly water treatment — added directly to your pool or spa water to prevent calcium and mineral buildup before it starts. Simple, consistent, effective.
Weekly Maintenance • Pool and Spa Safe • Prevents Future Buildup
Use all three together for complete, season-long calcium defense.

Frequently Asked Questions
What is the Pool Hero System?
The Pool Hero System is a three-step solution from LayorCare for managing calcium and mineral buildup in pools and spas. Step 1 (Clean) uses Heavy Calcium Releaser to remove existing calcium and scale. Step 2 (Protect) applies Cal Block to seal surfaces with a nano-barrier. Step 3 (Treat) uses Pool Hero as a weekly water treatment to prevent new buildup. Used together, they keep surfaces clean and water clear all season.
How much Pool Hero do I add to my pool?
For startup or problem water, add 8 oz per 10,000 gallons directly to the pool with the pump running. For weekly maintenance once your water is conditioned, add 4 oz per 10,000 gallons once per week, poured slowly around the perimeter of the pool. No pre-dilution is needed.
How soon can I swim after adding Pool Hero?
You can swim 30 minutes after application.
How long does one gallon of Pool Hero last?
Most pools use one gallon every 8 to 10 weeks, depending on pool size and calcium levels. Larger pools and pools in hot, high-calcium regions such as Arizona, Nevada, Texas, and Southern California typically run an 8-week cycle. Standard residential pools with normal calcium levels usually run a 10-week cycle.
How does Pool Hero prevent calcium buildup?
Pool Hero keeps calcium and minerals suspended in the water so they cannot bond to tile, surfaces, and equipment and harden into white scale. By treating the water before deposits can form, it stops scale at the source rather than removing it after the fact.
Is Pool Hero safe for all pool surfaces and finishes?
Yes. Pool Hero is safe for all pool surfaces and finishes, including tile, plaster, pebble, and vinyl, and it will not etch or damage them. It is pH-neutral and will not disrupt your water chemistry.
Is Pool Hero compatible with salt, chlorine, and bromine systems?
Yes. Pool Hero works with chlorine, bromine, and saltwater generators, and it is safe for heaters and filters. Spa Hero is compatible with both bromine and chlorine spa systems.
Do I need to remove existing calcium before using Pool Hero?
For best results, yes. If you already have calcium deposits, start with Heavy Calcium Releaser (Step 1) to remove existing buildup, then seal with Cal Block (Step 2) before beginning weekly Pool Hero treatment (Step 3). On a clean pool, you can begin weekly treatment right away.
What does PFAS-free mean, and why does it matter?
PFAS are a group of synthetic forever chemicals that do not break down naturally and can accumulate in the environment. Every Pool Hero product is formulated without PFAS, so it is safer for your family, your pets, your surfaces, and the environment.
Will the Heavy Calcium Releaser harm my pool tile or change my water chemistry?
Heavy Calcium Releaser is acid-free and will not affect your pool's pH. It dissolves heavy calcium, scale, and efflorescence from tile, coping, stone, and water features without acid washing or bead blasting. It will not etch most surfaces, but as with any strong cleaner, always test in an inconspicuous area first.
How often do I apply Cal Block?
Cal Block is a spray-on, wipe-off nano-barrier. Apply every 3 to 6 months to greatly reduce calcium, scale, and efflorescence buildup and to keep future cleanings easy. Most pool owners apply at the start of the season and again after any major surface cleaning.
What comes in the Pool Hero System Bundle?
The bundle includes 1 quart of Heavy Calcium Releaser, one 24 oz trigger spray of Cal Block, and 1 gallon of Pool Hero Weekly Water Treatment. That is everything you need to clean, protect, and treat, in one package for $139.
Can I subscribe instead of reordering every time?
Yes. Subscribe and save 12% plus free shipping on every subscription order. Choose delivery every 8 weeks or every 10 weeks based on your pool size. Subscriptions auto-renew and you can skip or cancel anytime.
Is the Pool Hero System for homeowners or professionals?
Both. The Pool Hero System uses the same professional-grade formulas trusted by pool service pros, packaged with simple weekly dosing and spray-on application so any homeowner can get pro-level results without the guesswork.
Stop Scrubbing. Start Swimming.
Four ounces a week is all it takes to keep calcium off your tile for good.
