Prevent II - Multi Purpose Concentrate - 500 ml

Prevent II is a multi-purpose liquid concentrate which eliminates staining and scale formation.

Heater Insurance in a Bottle

Have you ever felt a "sandpaper" texture on your spa shell? Or noticed cloudy water that just won't clear up, even with chlorine? That is usually Calcium Scale and suspended metals attacking your tub.

Prevent II is your defense shield.

This powerful liquid concentrate acts as a "magnet" for minerals. It wraps itself around calcium, iron, and copper particles in the water, stopping them from sticking to your spa surface or clogging your heater element. It keeps these minerals floating harmlessly in the water so your filter can grab them, leaving you with polished, crystal-clear water.

The "Phosphate-Free" Difference

Many cheap scale removers are made with Phosphonic Acid. The problem? When that breaks down, it turns into Phosphates—which is the #1 food source for algae.

• The Prevent II Advantage: Our formula is 100% Phosphate-Free. It protects your equipment without creating an algae buffet in your hot tub.

Three Problems, One Solution:

1. Stops Scale: Prevents calcium crust from forming on your heater element (the #1 cause of heater failure).
2. Prevents Stains: Stops dissolved metals (like iron or copper from your fill water) from rusting or staining your beautiful cedar or acrylic shell.
3. Clarifies Water: Helps bind tiny mineral particles together so your filter can catch them, fixing that "dull water" look.

When should you use it?

1. The "Fresh Fill" (Crucial Step)

The most important time to use Prevent II is the minute you fill your hot tub.

Tap water and well water are full of heavy metals and minerals.5 Adding Prevent II before you add chlorine prevents these minerals from reacting and turning your water green or brown.

• Dosage: Add a heavy initial dose (check label) while filling.

2. Weekly Maintenance

Water evaporates, but minerals stay behind. Over time, your water gets "harder" and harder.

• Dosage: Add a small weekly maintenance dose to keep the protection barrier active and your heater efficient.

3. "Sandpaper" Shell

If your acrylic or wood surface feels rough, you have scale buildup. A strong dose of Prevent II can effectively slowly dissolve this layer back into the water over a few days.

Is this safe for Cedar Tubs?

Yes. Calcium buildup can turn beautiful red cedar into a dull, white-grey color. Using Prevent II regularly keeps the wood grain looking rich and clean by preventing mineral deposits from settling into the wood fibers.
