✓ Side Fillport + 2 Funnels (Initial Fill & Service)
✓ 250 lbs Calcite in 5 × 50 lb Bags
✓ + One 50 lb Bag of FloMag (Calcite + FloMag option)
👨🔧 Installed by a Licensed Plumber
We recommend installation by a licensed plumber, and Aidan supports your plumber by phone at 800-460-5810, 7 days a week. The tank goes on your main line after the well pressure tank; there is no drain line or outlet to run. Your plumber brings the pipe, the fittings and a shutoff valve. Most plumbers charge $600 to $800, and some quote $1,200 to $1,500. See every step in our acid neutralizer install guide.
How it arrives: the tank ships empty. The calcite comes in five 50 lb bags (plus one 50 lb bag of FloMag on the Calcite + FloMag option) and is loaded into the tank at install through the fillport with the included funnel. The empty tank is easy to carry inside; the heaviest single piece is a 50 lb bag.
Non-backwashing, no drain line, no electricity.
Installs directly into your main water line with standard 1″ threaded connections. Designed for straightforward installation by a licensed plumber; Aidan supports your plumber by phone at 800-460-5810.
Vortech® Technology uses a patented internal distributor system to maximize media contact, reduce channeling, and deliver consistent treatment across the entire tank.
The result is higher efficiency, longer media life, and reliable performance without unnecessary complexity or wasted capacity.

Orders are verified and sent to our Ohio facility. Your system is picked, palletized, and shrink-wrapped in secure, damage-resistant packaging.
Freight Shipment
In stock systems typically ship within 3 to 5 business days. We use heavy freight carriers (usually RNL). You will receive a tracking number via email.
Transit Time
Free shipping to the lower 48 states.
• 1–2 business days (East Coast/Midwest)
• 4–5 business days (West Coast)
Liftgate Delivery
Due to the weight, delivery is via liftgate truck to your driveway or curb.
Why isn't this 1-day shipping like Amazon?
Unlike a standard Amazon package, this shipment is heavy and gets delivered on a pallet. It requires specialized pallet handling, tractor-trailers, and liftgates to ensure it arrives safely. We prioritize damage-free delivery over speed.
"I never give reviews but this product was 5 stars from start to finish. So refreshing to deal with a company that lives up to what they advertise." ★★★★★
Jack S, Maryland
"Side fill port makes media changes easy. Arrived fast, installed solo without issues, and the calcite media quality is far better than local supply." ★★★★★
Daniel M, Cape Cod
"Easy installation, excellent water flow, wish I had bought this 20 years ago. - Feb 7th 2026" ★★★★★

The Most Reliable Fix for Acidic Well Water
Trusted in 1,200+ homes. NSF/ANSI 61 certified components. 10-year tank, 5-year valve warranty.
Eliminate blue-green stains and protect your copper pipes from corrosion with the 2.5 CF Acid Neutralizer. Designed specifically for well water with low pH (4.0 - 6.9), this system uses natural calcite media to gently neutralize acidity on contact. Unlike undersized units found in big box stores, our massive 2.5 cubic foot capacity ensures consistent pH correction and needs a calcite level check only once a year, with more calcite about every three years. Featuring the industry-standard Clack® control valve and advanced Vortech® tank technology, you get professional-grade performance and flow rates without the price tag.

Frequently Asked Questions
We recommend installation by a licensed plumber, and Aidan supports your plumber by phone at 800-460-5810, 7 days a week. A non-backwashing unit typically takes a plumber about 2 hours; a backwashing unit also needs a drain line (drain tubing is not included) and a standard outlet. The bypass valve comes already installed on the control valve, and our install video walks through every step.
Check the level once a year: hold a bright flashlight behind the tank and look for the shadow of the calcite. When it is about halfway down, add calcite with the included funnel, filling to about 10 inches below the fill port. How long that takes depends on the tank size: about every 6 to 12 months on a 1.0 cubic foot tank, 18 to 24 on a 1.5, 24 to 30 on a 2.0 and 30 to 36 on a 2.5. A calcite and FloMag blend does not change it. You never replace the calcite; it dissolves as it works.
Not noticeably. The Vortech tank has no gravel bed, and its distributor plate spans the whole tank. Pressure drop is not something our customers call about. Rated flow depends on the size (the 2.5 cubic foot non-backwashing tank is rated up to 17 GPM), and this model's number is in the specifications tab above.
The unit ships via freight truck with liftgate service. The driver will lower the pallet to your driveway or curb. You are responsible for disposing of the wooden pallet and cardboard packaging. The tank itself is lightweight when empty (~25 lbs) and easy to move into your garage or basement before filling it with the included media.
It depends on the model. The non-backwashing models (Clack C1190 head) need no electricity and no drain line. The backwashing models (Fleck 5600SXT and 2510SXT valves) plug into a standard outlet and need a drain line for the backwash; drain tubing is not included.

Investing in The Right System
Many systems look identical online, but cheaper options often cut corners.
Found this neutralizer cheaper somewhere else?
Many Amazon and discount sellers use similar photos and product titles.
The system may look similar at first glance.
But to advertise a lower price, key components are often downgraded or removed.
Cheap systems commonly use thinner tanks, less filtration media, and provide little to no technical support.
When something goes wrong, you're usually on your own.
➜ This is the best price we can offer without cutting quality or support.

Do it right the first time. By investing a little more upfront, you prevent early replacement costs, plumbing repair headaches, and the frustration of poor water quality. This is without a doubt the best long-term option for your home.
What You're Actually Paying For
No Media Skimming: We provide the exact optimal amount of the highest grade media. Competitors frequently underfill tanks by 20-30% to cut costs, severely reducing your system's effectiveness.
Premium Structural Tanks: Our systems utilize heavy-duty, pressure-tested USA vortech structural tanks built to last decades, preventing cracked tanks and flooded basements.
Genuine Warranties: Discount retailers are often selling tanks imported overseas, meaning less structural integrity and no warranty. Our tanks carry full manufacturer backing with a 10 year warranty. We've tried tanks from Mexico in the past to reduce cost for our customers and all it did was create problems.
Lifetime USA Tech Support: With over 30 years of industry experience, we actually pick up the phone. We provide tech support 7 days a week between 8AM - 5PM EST.

1-Year Risk-Free Guarantee
Proven in Thousands of Real Homes
The Policy:
If it doesn’t fix your acidic water, we’ll refund you. No returns required.
After 30 years of testing acidic water solutions, the data led us to this exact system. With a track record of 1,000+ successful installations, we have the evidence to offer a true risk-free guarantee based on results, rather than an empty marketing gimmick.
The Industry "Return Policy" Trap
+
Most water filter companies offer standard "Money Back Guarantees" or return policies fully knowing that you aren't going to drain, package, and pay heavy freight costs to ship a 600lb wet tank back to them. It's an illusion of safety. Our guarantee requires zero return shipping.
How Our Real Guarantee Works
1
It Fails to Fix the Acidic Water
If the system does not neutralize your pH as promised.
2
Aidan Troubleshoots With You
You'll work directly with the expert who designed your system to ensure it's set up correctly for your specific well chemistry.
You Get Refunded
If it still doesn't solve the problem, we refund you entirely. No return shipping required.
Not sure if this is the perfect system? Don't guess. If you aren't 100% sure this is the correct size for your well, text me your water test or call me directly. I'll personally review it.
