If you have a saltwater pool, you already made a smart choice. The water feels better than a traditional chlorine pool, you're not hauling buckets of tablets, and your chlorine generator does the heavy lifting all season. But here's something a lot of salt pool owners don't know: a plain saltwater pool is only half the picture.

BioGuard Mineral Springs takes everything you love about your salt pool and makes it noticeably better — softer water, sparkling clarity, less weekly maintenance, and built-in protection for your chlorine generator cell. And right now, we have a limited quantity of BioGuard Mineral Springs Convert at a price that makes switching a no-brainer. More on that in a minute.

1 What Is BioGuard Mineral Springs?

Mineral Springs is BioGuard's premium salt pool system. It works with your existing chlorine generator — no new equipment needed for existing salt pool owners — and replaces plain pool salt with a proprietary blend of ultra-pure minerals that does far more than salt alone.

The system is built around three products:

Product When Used What It Does
Beginnings Start of season / new pools Establishes the mineral environment — ultra-pure salt, stabilizer, water softener, scale inhibitor, algaecide
Convert Existing salt pool owners Converts a plain salt pool to Mineral Springs mid-season — includes SunShield stabilizer
Renewal Weekly maintenance Replenishes minerals, manages pH drift, protects the cell — one bag per week, about 5 minutes

2 Plain Salt Pool vs. Mineral Springs: What's the Difference?

This is the comparison that makes people do a double take. Plain salt pools are great — but they leave a lot on the table. Here's how the two systems stack up side by side:

Feature Plain Salt Pool BioGuard Mineral Springs
Water feel Soft vs. chlorine tabs Silky, velvety smooth — noticeably better
Water clarity Good Sparkling — built-in clarifier makes the water pop
Stabilizer (CYA / SunShield) Must add separately — easy to forget Built in — chlorine protected from sun degradation automatically
pH management pH constantly drifts high — must manage manually Renewal includes pH decreaser — drift managed automatically
Algae prevention Must add algaecide separately Built into Beginnings and Renewal
Cell protection Scale buildup shortens cell life Scale inhibitor built in — extends cell life significantly
Weekly maintenance Test and add multiple products each week One bag of Renewal — about 5 minutes a week

💧 The SunShield Difference

Your chlorine generator produces unstabilized chlorine — and Minnesota summer sun burns through unstabilized chlorine fast. Without stabilizer (CYA), your cell has to work overtime all day just to keep up. Mineral Springs has SunShield built right in, so the chlorine your cell produces actually lasts. That means less cell run time, longer cell life, and consistently sanitized water even on the hottest days of summer.

3 What If I Have a Traditional Chlorine Pool?

Mineral Springs works with any chlorine generator — so if you've been thinking about making the switch from chlorine tablets to a salt system, this is a great time to do it right from the start. You'll need to add a chlorine generator to your equipment pad, but once that's in place the Mineral Springs system runs the same way.

The difference in water feel and clarity between a chlorine tab pool and a Mineral Springs pool is dramatic. If you've ever swum in a high-end resort pool and wondered why it felt so different from yours — this is usually why. Stop in and talk to us about what a generator installation would involve for your pool.

⚠️ Heads Up: You'll Need a Chlorine Generator

Mineral Springs requires a chlorine generator (salt cell) to work. If you're currently on chlorine tablets, switching to Mineral Springs means adding a generator to your equipment pad. It's a one-time equipment cost — but the payoff in water quality and reduced weekly maintenance is significant. Come talk to us and we'll walk you through what's involved.

4 Already Have a Salt Pool? Here's Your Deal.

If you already have a salt pool with a chlorine generator, converting to Mineral Springs is simple — and right now it's incredibly affordable. We happened to come across a supply of BioGuard Mineral Springs Convert at a great price, and we're passing every penny of that savings on to our customers.

Convert is normally $53.99 per bag — one bag treats 5,000 gallons. For a limited time we're offering 70% off while our supply lasts. We only have 44 bags on hand, so this won't last long.

Pool Size Bags Needed Convert Cost (70% off) MS Scale Inhibitor Total Approx.

📌 Don't Forget: Mineral Springs Scale Inhibitor Completes the Conversion

Along with Convert, you'll need Mineral Springs Scale Inhibitor to complete your conversion and protect your chlorine generator cell from scale buildup.

It's not on sale, but it's a smart investment that pays for itself by extending the life of your cell.
