Product Overview

Technicians reach for Regal Xtreme Tabs when they need a multi-functional sanitizer that manages water clarity and scale prevention in a single application.

Unlike standard chlorine pucks, these 0.5 LB tablets contain 94.05% Trichloro-s-triazinetrione and are formulated as a 6-in-1 solution. This Regal product reliably handles bacteria and algae while incorporating a clarifier and scale inhibitor to protect pool surfaces. In our experience, premium pool care programs offer improved water quality by addressing mineral buildup and fine debris alongside routine sanitation.

Why Pool Pros Trust This

Benefits & What Makes It Different

94.05% Trichloro-s-triazinetrione

This high-concentration active ingredient provides consistent chlorine delivery to maintain a 1-4 ppm residual for safe swimming conditions.

Integrated Clarifier and Sequesterant

The blended formula helps prevent unsightly staining and damaging scale from forming on plaster and tile while keeping water crystal clear.

Slow-Dissolving 0.5 LB Tablet

Designed for use in floaters or erosion feeders, these tablets dissolve at a steady rate to ensure your sanitizer levels do not fluctuate wildly.

Product Details

Active Ingredient

Trichloro-s-triazinetrione 94.05%

Recommended Dosing

1 tablet (0.5 LB) per 10,000 gallons weekly to maintain 1-4 ppm chlorine residual.

Compatibility

  • Do not mix with other types of chlorine (like Cal-Hypo) in the same feeder
  • Wait until chlorine levels drop below 4 ppm before swimming

When To Use This

Routine weekly sanitation for inground and above-ground poolsPreventing scale buildup in areas with high calcium hardnessMaintaining water clarity in pools prone to dullness or fine suspended particles

Pro Tip

In regions with high evaporation and intense sun, monitor your stabilizer (CYA) levels monthly; if they exceed 90-100 ppm, you may need to partially drain and refill to maintain chlorine effectiveness.

Common Questions & Instructions

How many 3-inch Xtreme tablets do I need for a 10,000 gallon pool?

For a typical 10,000-gallon pool, we recommend starting with one 0.5 LB tablet per week in a chlorinator or floater to maintain a chlorine level of 1-4 ppm, though heavy bather loads or high heat may require more.

Do Regal Xtreme Tabs contain cyanuric acid or stabilizer?

Yes, as a Trichloro-s-triazinetrione based product, these tablets add cyanuric acid (CYA) to the water, which protects your chlorine from being depleted by UV rays in hot climates.

Can I use these tablets in a vinyl liner pool without causing damage?

While safe for vinyl, these tablets should never be tossed directly into the pool; always use a proper feeder or floater to prevent localized high acidity that can bleach or weaken the liner.
