How to Use the Aqualix IC15 Salt Cell: Complete Guide

Step 1: Initial Setup and Installation

1. Power Down: Turn off the power to your pool pump and IntelliChlor power center at the circuit breaker.
2. Remove Old Cell: Unscrew the unions connecting your old IC15 cell from the plumbing. Disconnect the communication cable from the power center.
3. Install New Cell: Apply fresh Teflon tape or pipe sealant to the union threads. Screw the new Aqualix cell into your plumbing line, ensuring flow direction arrows match water flow (typically from the filter toward the return jets).
4. Make Electrical Connection: Plug the included cable from the new cell into the socket on your existing EC-520888 power center.

Step 2: First-Time User Guide

1. Power On: Restore power at the circuit breaker. Start your pool pump to ensure water is flowing through the new cell.
2. Check for Alerts: Observe the power center display. It should go through its normal startup sequence. The “Flow” and “Cell” lights should be green if installation is correct.
3. Verify Salt Reading: Allow the system to run for a few minutes. The power center will display the salt concentration. Compare this to a manual test strip reading for accuracy.

Step 3: Core Functions and Daily Use

Your daily interaction will be with the Pentair power center. Use the buttons to adjust the chlorine output percentage based on your pool’s needs (e.g., 40% in mild weather, 80% during a heatwave or heavy use). The display will show sanitizer output and salt level. The system works automatically from there, generating chlorine as the pump runs.

Step 4: Advanced Techniques

For integrated systems, if you have Pentair automation (like an EasyTouch or IntelliTouch panel), you can control the chlorine output remotely. The Aqualix cell responds to these automation commands exactly like an OEM cell. You can also use the “Super Chlorinate” function on the power center for a 24-hour boost.

Step 5: Maintenance and Care

Every 3-6 months, or when you see visible scale buildup on the blades, clean the cell. Prepare a 4:1 water-to-muriatic acid solution in a bucket. Remove the cell and submerge the blade assembly (not the entire cell) for 5-10 minutes until fizzing stops. Rinse thoroughly with water. Reinstall. Never use mechanical tools to scrape the blades. For a deeper dive, our salt cell cleaning guide has detailed tips.

Step 6: Troubleshooting Common Issues

Issue: “Low Salt” alert despite correct salt levels.
Solution: This is where the upgraded flow sensor helps, but ensure your pool water’s salinity is 2700-3400 ppm. Clean the cell’s blades, as scale can interfere with the reading.
Issue: No chlorine production.
Solution: Verify the cell is receiving power (listen for a slight hum or check for bubbles inside when the pump is on). Ensure the output percentage is set above 0% and the pump runtime is sufficient. If problems persist, the decision to buy IC15 salt cell replacement might need vendor support. Purchasing from a reputable source ensures you have access to the manufacturer’s 24-hour support claim.

Performance & Real-World Testing

Testing Methodology

We installed the Aqualix IC15 on a standard 13,000-gallon inground pool with a Pentair EC-520888 power center. Testing was conducted over an eight-week period through the peak of summer, monitoring chlorine stability, salt reading accuracy, ease of use, and any system alerts. We compared its performance to the original Pentair IC15 cell it replaced.

Performance Metrics

Chlorine Production & Stability: The cell consistently maintained free chlorine levels between 2-4 ppm with the output set between 50-60%. Performance was indistinguishable from the OEM cell under normal conditions.
Salt Reading Accuracy: The displayed salt reading was within 200 ppm of test strip results, which is acceptable for residential use. We experienced no false “low salt” alarms, a common complaint with some aftermarket cells.
Efficiency & Power Draw: Measured power consumption at the power center was consistent with expected values for a cell of this capacity.

Real-World Scenarios

During a heavy weekend with multiple swimmers, we increased the output to 80%. The cell responded effectively, preventing a chlorine dip. After a major rainstorm, a slight chlorine drop occurred, but raising the output temporarily quickly corrected it, demonstrating responsive control.

Claims vs. Reality

Aqualix’s claims of “upgraded durability” and “reduced false alerts” held true in our testing. The physical build is solid, and the flow sensor performed reliably. The claim of being “gentler on eyes and skin” is a function of saltwater chlorination in general, not this specific cell, but it delivered on that core promise. For those weighing the IC15 salt cell pros cons, its reliable performance is a major pro.

Pros and Cons

What We Loved (Pros)

• Significant Cost Savings: Priced notably lower than a genuine Pentair IC15, it offers the core functionality at a fraction of the cost, providing excellent value.

Expert Tips for Maximum Value

Tip #1: Pre-Installation Verification

Before you buy IC15 salt cell replacement, double-check your existing power center model number. It must be an EC-520888. Using it with an incompatible power center can damage the cell or void any support.

Tip #2: Establish a Cleaning Schedule

Preventative maintenance is key. Inspect the cell’s blades every 3 months. Regular cleaning prevents scale from insulating the blades, forcing the system to work harder and shortening its life.

Tip #3: Use a Compatible Salt Test Kit

Don’t rely solely on the power center’s digital readout. Use a high-quality salt test kit or strips weekly to manually verify salinity. This cross-check ensures the cell is reading accurately and producing chlorine efficiently.

Tip #4: Optimize Pump Runtime

The cell only generates chlorine when the pump is running. Ensure your pump’s daily runtime is sufficient for your pool’s needs and climate. An undersized pump runtime is a common cause of low chlorine, mistaken for a faulty cell.

Tip #5: Balance Your Water First

Before installing any new salt cell, ensure your pool water is balanced: pH (7.4-7.6), Alkalinity (80-120 ppm), and Calcium Hardness (200-400 ppm). Balanced water maximizes cell efficiency and lifespan.

Tip #6: Store the Old Cell

If your old cell isn’t completely dead, clean it and store it as an emergency backup. In a pinch, even a cell at 50% capacity can keep your pool sanitized while you await a replacement.

Common Mistakes to Avoid

1. Mistake: Installing the cell with water flow in the wrong direction. → Solution: Always align the flow arrow on the cell housing with the direction of water flow from your filter to your pool returns.
2. Mistake: Running the cell without adequate water flow (pump off or a clogged filter). → Solution: The cell can overheat and fail. Always ensure the pump is on and the filter is clean before the cell is powered.
3. Mistake: Using the wrong type of salt. → Solution: Only use high-purity, water-softening salt or salt specifically labeled for pools. Avoid salt with anti-caking agents or additives.
4. Mistake: Forgetting to clean the cell regularly. → Solution: Set a calendar reminder every 3 months to inspect and clean the cell. Visual scale is a clear sign it’s time.
5. Mistake: Setting the chlorine output percentage too high indefinitely. → Solution: This wastes energy and wears the cell faster. Adjust the output seasonally—lower in cool weather, higher in hot weather or during heavy use.

Pricing & Where to Buy

Frequently Asked Questions

Is the Aqualix IC15 Salt Cell worth the money?

Absolutely, for the right user. If you already own the compatible Pentair power center, spending $899 on this cell versus $1200+ on an OEM part is a significant savings with no observable drop in day-to-day performance in our tests. The value proposition is its strongest selling point, making the debate on IC15 salt cell worth buying lean heavily in its favor.

How does it compare to a generic eBay replacement cell?

There’s a stark difference. Generic cells often use uncoated titanium blades and basic sensors, leading to shorter lifespans and frustrating false error codes. The Aqualix invests in ruthenium coating and an improved flow sensor, addressing the two biggest flaws of budget options. You pay a bit more for much greater reliability.

What’s the learning curve for beginners?

Very low if you’re replacing an existing IC15. It’s a direct physical and electrical swap. The learning curve is identical to using the original Pentair system—you control everything from the same familiar power center. First-time salt system owners should spend an hour understanding basic pool chemistry and pump runtime settings.

What accessories or additional items do I need?

You must have the Pentair EC-520888 power center. You will also need pool salt to establish salinity, a salt test kit, muriatic acid for periodic cleaning, and Teflon tape for installation. A quality test kit is a non-negotiable accessory for proper maintenance.

What warranty and customer support does it offer?

Warranty terms should be confirmed on the product listing, but expect a standard 1-2 year limited warranty. Aqualix promotes 24-hour customer support for installation and sizing questions, which provides more post-purchase support than most no-name brands.

Where can I buy it at the best price?

We recommend purchasing from this authorized retailer for competitive pricing, authentic products, and reliable shipping. Amazon often has the best price and a straightforward return process.
