Iron and Sulfur Removal Systems
What Actually Changes When Your Water Gets Fixed
That rotten egg smell disappears. Not just masked—gone. Hot water stops smelling worse than cold, and guests stop giving you that look when they turn on the tap.
Orange stains quit showing up on your toilets, sinks, and tubs. You’re not scrubbing rust rings every week or replacing fixtures because the damage already happened. Your plumbing stops corroding from the inside out, and your water heater lasts years longer.
You stop buying bottled water for coffee and cooking. Your ice cubes don’t taste off. Showers don’t leave that sulfur smell on your skin. The whole house just works the way it should—without you thinking about the water every time you use it.
Well Water Treatment Experts in Secret Cove
We've Been Fixing Florida Well Water for Decades
We have over 50 years of combined experience treating well water across Central Florida. We’re A-rated with the Better Business Bureau, hold a 5-star rating with zero complaints, and we’re members of the National Water Quality Association.
Secret Cove sits on the same limestone aquifer system that creates well water problems throughout Jacksonville’s Southside. We know exactly what’s in your water because we’ve treated hundreds of homes dealing with the same iron, sulfur, and bacteria issues. We’re not a national franchise that disappears after the install—we’re Florida-based, and we service everything we sell.
If you’re military or a first responder, we offer a $500 discount. It’s one way we give back to the people who serve this community.
How Well Water Filtration Works
Here's What Happens From Start to Finish
We start with a water test. Not a generic one—a full analysis that tells us exactly what’s in your well water and at what levels. Iron, sulfur, bacteria, pH, hardness. That determines which system you actually need.
Once we know what we’re dealing with, we recommend either an air injection oxidation system or a hydrogen peroxide injection system, paired with catalytic carbon filtration. Air injection is chemical-free—it uses oxygen to oxidize iron and sulfur so they can be filtered out. Hydrogen peroxide is more aggressive and works better for higher contamination levels or stubborn iron bacteria. Both break down contaminants before the water reaches your house.
Installation happens at your main water line, before the water reaches any faucet or appliance. That means every drop gets treated—showers, kitchen, laundry, everything. We handle the install, test the system, and make sure it’s dialed in before we leave. You’re not figuring this out on your own.

What You're Getting With a Whole-House System
A whole-house well water filtration system treats water at the point of entry. That’s different from an under-sink filter or a pitcher—you’re protecting your entire home, not just one tap.
In Secret Cove and across Jacksonville’s Southside, the most common problems are hydrogen sulfide (that rotten egg smell), iron staining, and iron bacteria. Florida’s warm limestone aquifer creates perfect conditions for sulfur-reducing bacteria to thrive. They colonize your water heater and plumbing, making the problem worse over time.
Our systems use oxidation to neutralize these contaminants. Air injection oxidation works for moderate contamination and doesn’t require chemicals. For tougher cases—high iron counts or established bacteria colonies—we use hydrogen peroxide injection. It’s a stronger oxidizer than chlorine and breaks down into just oxygen and water. No chemical residue.
After oxidation, water passes through a catalytic carbon filter that captures the oxidized particles. The result is clean, clear, odor-free water throughout your home. Your plumbing stays protected, your appliances last longer, and you’re not dealing with stains or smells anymore.
What causes the rotten egg smell in my Secret Cove well water?
Hydrogen sulfide gas. It forms when sulfur-reducing bacteria break down sulfates in your groundwater. Florida’s limestone aquifer contains abundant sulfur deposits, and the bacteria that feed on them thrive in warm conditions.
These bacteria often colonize your water heater because they prefer the heat. That’s why your hot water smells worse than cold. The smell itself isn’t usually a health risk, but it’s a sign that bacteria are present in your plumbing system—and that can lead to corrosion and buildup over time.
The only real fix is oxidation. You need to convert the hydrogen sulfide into a solid form that can be filtered out. Air injection or hydrogen peroxide injection both work, depending on how severe the problem is. Temporary fixes like carbon filters get saturated fast and don’t address the bacteria causing it.
Will a well water filtration system remove iron stains from my fixtures?
It’ll stop new stains from forming. The existing orange rings and streaks need to be cleaned off, but once your system is running, you won’t see them come back.
Iron in your water oxidizes when it hits air—that’s what creates the rust-colored staining on toilets, sinks, and tubs. A filtration system removes the iron before it reaches your fixtures, so there’s nothing left to oxidize and stain.
If you’ve got iron bacteria in your plumbing, that’s a bigger issue. These organisms feed on iron and create slimy, rust-colored buildup that’s harder to remove. A hydrogen peroxide injection system can kill iron bacteria and prevent them from recolonizing your pipes. Once they’re gone and your water’s treated, the staining stops.
How much does a whole-house well water filtration system cost in Secret Cove?
It depends on what’s in your water and what system you need. A basic air injection oxidation system runs less than a hydrogen peroxide injection setup with advanced filtration. Water testing, contamination levels, and your home’s plumbing all factor in.
What matters more than upfront cost is what you’re preventing. Untreated well water damages water heaters, washing machines, dishwashers, and plumbing fixtures. Replacing a corroded water heater costs more than installing a filtration system that would’ve protected it. Add in the ongoing cost of bottled water, stain removers, and appliance repairs, and a whole-house system pays for itself.
We offer a $500 discount for military and first responders. After we test your water, we’ll give you a clear recommendation and a straightforward price—no upselling, no surprises.
Do I need to test my well water before installing a filtration system?
Yes. You can’t fix what you don’t measure. A proper water test tells us exactly what contaminants are present and at what concentrations—iron, sulfur, bacteria, pH, hardness, nitrates. That determines which system will actually work for your water.
Florida doesn’t require routine testing for private wells, but the CDC recommends testing for coliform bacteria and nitrates at least once a year. If you’re noticing odors, stains, or taste issues, you should also test for iron, hydrogen sulfide, and pH levels.
We handle the testing as part of the process. Once we have the results, we can recommend the right filtration setup—whether that’s air injection, hydrogen peroxide injection, or a combination system. Guessing or installing the wrong equipment just wastes money and doesn’t solve the problem.
What's the difference between air injection and hydrogen peroxide injection systems?
Both oxidize contaminants so they can be filtered out, but they work differently. Air injection is chemical-free—it injects oxygen into your water, which oxidizes iron and sulfur. It works well for moderate contamination levels and doesn’t require ongoing chemical purchases.
Hydrogen peroxide injection is more aggressive. It’s a stronger oxidizer than air, chlorine, or potassium permanganate, and it’s especially effective against iron bacteria and high sulfur levels. Hydrogen peroxide breaks down into just oxygen and water, so there’s no chemical residue left behind.
If your water has a mild rotten egg smell and some iron staining, air injection usually handles it. If you’ve got heavy contamination, established bacteria colonies, or a strong sulfur odor that won’t quit, hydrogen peroxide is the better option. We test your water first and recommend whichever system fits your situation—not whichever one we want to sell.
