Outsmart Algae Before It Starts with Natural Enzymes

When the heat spikes and storms roll in, algae doesn't wait for an invitation. But what if you could take away its favorite snack — phosphates — before it ever shows up?

That’s exactly what WATER TRENDS Phos Cure products are designed to do. Whether you're opening for the season, tackling high phosphate levels, or maintaining weekly clarity, there’s a formula for every need — and they all work together to keep your pool water looking its absolute best.

Why Phosphates Matter

Phosphates are the invisible culprit behind algae blooms. They sneak into your pool through rain, leaves, fertilizer runoff, and even bathers — and once they build up, algae feeds on them like an all-you-can-eat buffet.

To stop algae at the source, WATER TRENDS created a simple three-step phosphate management system:

💪 1. Phos Cure MAX – Knock Out High Phosphate Levels

When phosphates are reading above 1,000 ppb, it’s time to use maximum effort.

Phos Cure MAX is a highly concentrated formula that neutralizes up to 1,000 ppb in one dose. It’s your best defense against persistent algae caused by phosphate overload.

How to Use It:

• Test your water at The Great Escape for an accurate phosphate reading

• Balance pH and alkalinity before use

• Add 16 oz per 10,000 gallons into your skimmer with the filter running

• Circulate for 24 hours, then backwash within a week

🌀 A temporary haze is totally normal — that means it's working.

🔁 2. Phos Cure Weekly – Routine Maintenance for Ongoing Control

After using MAX or if your phosphate levels are already under control, Phos Cure Weekly becomes your weekly support system. This natural enzyme blend keeps phosphate levels low while also helping prevent waterline scum and cloudiness.

How to Use It:

• Add 4 oz per 10,000 gallons to the skimmer weekly

• Run the filter for 24 hours

• Hold off on shocking the pool for 1–2 days after application

🌱 Use it weekly to stay ahead of phosphate buildup, especially during hot weather or heavy use.

🔄 3. Phos Cure Open/Close – Seasonal Prep & Protection

Bookending your swim season with Phos Cure Open/Close gives your pool a clean start and a protected finish. This broad-spectrum formula dissolves oils and lotions while eliminating phosphates — setting your pool up for success, even in the off-season.

How to Use It:

• Add 1 quart per 20,000 gallons about a week after opening or during closing

• Shake well and pour directly into the pool

• No waiting required — swim right after!

🏁 It’s a perfect one-step addition to your opening or closing routine.
