Spa-Tabs - Stabilized Chlorinating Tablets - 2KG

For chlorination, Spa-Tabs should be added to an automatic chlorinator, floating chlorine feeder, or spa skimmer to maintain proper chlorine residual.

The "Set It and Forget It" Solution for Acrylic Spas

Let’s be honest: adding granular chlorine to your hot tub every single day is a hassle. If you miss a day or two (or go away for the weekend), you come back to cloudy, unsafe water.

Spa-Tabs solve that problem.

These are concentrated, slow-dissolving chlorine "pucks" that work in the background 24/7. Think of them as cruise control for your hot tub. You simply load them into your floater or feeder, and they release a steady, consistent stream of sanitizer to keep bacteria and algae at bay—even when you aren't home.

Is this right for your tub?

Before you buy, let’s make sure this fits your setup:

• YES for Acrylic/Fiberglass/Vinyl: If you have a standard modern spa, these are perfect.
• NO for Wood Tubs: If you have a Cedar or Redwood tub, do not use these. They are strong oxidizers that will turn your beautiful wood "fuzzy" and white over time. Stick to our Bromine or granular dichlor for wood!

Why our customers love the 2KG Pail:

• Less Work: You only need to refill your feeder once every week or so (depending on usage), rather than dosing daily.
• Vacation Ready: Going away? Pop a few tabs in your floater, and your water will still be clear when you get back.
• Best Value: This 2KG (4.4 lbs) pail is the bulk size. It lasts significantly longer than the small 1lb jars you see at big-box stores.

Detailed Guide: Mastering Your Water Chemistry

Understanding "Stabilized" Chlorine You might see the word "Stabilized" on the label and wonder if it matters. It absolutely does. "Stabilized" means these tablets contain Cyanuric Acid (CYA), which acts like a sunscreen for your chlorine. Without it, the sun’s UV rays can destroy the chlorine in your outdoor tub in a matter of hours. With Spa-Tabs, your sanitizer stays active longer, saving you money on chemicals.

The "pH Factor" (Important) While Spa-Tabs are incredibly convenient, they are naturally acidic (pH ~2.9).

• What this means for you: Over time, using tablets can slowly lower your spa's pH and Total Alkalinity.
• The Fix: Make sure you test your water weekly. If you see your pH dropping below 7.2, simply add a splash of pH Increaser to bring it back into the "Comfort Zone" (7.2 - 7.6). This small step prevents skin irritation and protects your heater from corrosion.

Getting the Dosage Right A common question we get is, "How many tablets do I use?" There isn't a "one size fits all" answer because every tub is different, but here is a good starting point:

• Start Low: Put 1 or 2 tablets in your floating dispenser.
• Adjust the Vents: Open the slots on the bottom of the dispenser halfway.
• Test: Check your water after 24 hours. If chlorine is below 3ppm, open the vents wider or add another tablet. If it’s too high (above 5ppm), close the vents slightly. Once you find the "sweet spot," you rarely have to touch it again!

Storage & Safety This 2KG pail is designed to last a long time, so proper storage is key. Keep the lid snapped tight to block out moisture. If moisture gets in, the tablets can degrade or release strong fumes. Always store them in a cool, ventilated place away from any acids or other pool chemicals.
