What ships: two empty tanks, both control valves (bypass valves already on), the brine tank, one fill funnel, and the Katalox-Light and resin in separate bags. A filled tank is too heavy to ship without damage, so the media goes in through the funnel at install. Not included: drain tubing and pipe adapters (your plumber supplies them). We recommend installation by a licensed plumber; Aidan supports your plumber by phone at 800-460-5810.

We recommend installation by a licensed plumber; Aidan supports your plumber by phone at 800-460-5810. Both tanks ship empty, and the media goes in at install. The iron filter needs a 120V outlet and a drain line (for backwash). The softener needs the same: 120V outlet and a drain. Drain tubing is not included, and your plumber supplies the pipe adapters.

⚠️ Order matters: The iron filter must come before the water softener. Dissolved iron fouls softener resin and shortens its life. Removing the iron first protects the softener resin, which on hardness alone can last for decades.
Step 1 - Iron Filter (Fleck 2510 AiQ)
- Shut off the main water supply and relieve pressure at a nearby faucet
- Position the tank on a level surface, near a drain (backwash sends water out during regen)
- Load the media: the tank ships empty. With the valve off the tank, cover the top of the center tube and pour the Katalox-Light in through the included funnel
- Connect inlet and outlet to the main water line through the bypass valve (water direction is marked on the valve head)
- Run the drain line from the valve to a floor drain, utility sink, or standpipe; your plumber sizes it for the backwash flow and the length of the run
- Hand-tighten the valve, then only a quarter to half turn with channel locks - over-tightening can crack the tank lip
- Plug the valve into a standard 120V outlet
- Open bypass slowly, let the tank fill, then switch to service
- Set the date and time on the 2510 AiQ valve (DATE/TIME on its Home menu). It comes programmed to clean itself (backwash) every day, which keeps the air pocket fresh
Step 2 - Water Softener (Fleck 5600SXT)
- Position the softener downstream of the iron filter
- Load the resin: the tank ships empty. With the valve off the tank, cover the top of the center tube and pour the resin in through the funnel
- Connect inlet and outlet to the main water line - water direction is marked on the valve head
- Run a 1/2" drain line from the valve to a floor drain, utility sink, or outside (max 20 feet)
- Plug in to a standard 120V outlet
- Add water softener salt to the brine tank; keep the salt level higher than the water level
- Open bypass slowly, fill the resin tank, then switch to service
- Program the 5600SXT valve: time of day, water hardness, and tank capacity
- Run the valve's start-up steps; Aidan walks your plumber through them by phone
Need help? Call 800-460-5810 or text Aidan at 443-277-2204, 7 days a week. He supports your plumber through the install and both valves' settings. No printed manual ships; the install guide and videos are online.

Two simple routines: The iron filter self-regenerates using air injection. You don't dose it with potassium permanganate or chlorine. The softener just needs salt. That's most of it.
Iron Filter Maintenance
- Every Day Automatic backwash. The 2510 AiQ valve cleans itself every day as shipped: it refreshes the air pocket and flushes iron and sediment out the drain. No action needed from you. On light water use it can be set to every 2 to 4 days.
- Annually Test your water. Confirm iron, manganese, and sulfur are still removed. If iron breakthrough starts showing up in toilet tanks or fixtures, regen frequency may need to increase.
- Every 6-8 Years Replace the Katalox-Light media. How long it lasts depends on your water use and iron level. Only the media is replaced; the tank and valve stay.
Water Softener Maintenance
- Monthly Check salt level. Keep the salt level higher than the water level; Aidan keeps a couple of bags in the brine tank.
- Annually Clean the brine tank. Let the salt run low and clean out any salt bridges or mushing that can impair regeneration.
- Rarely Replace the softener resin. On hardness alone resin can last for decades; iron that reaches it shortens its life. Signs of worn resin: hard water returning, increased salt usage, or resin beads in water.
- As Needed Check the venturi and injector. If regeneration seems sluggish, the venturi assembly may need cleaning. Takes 5 minutes with no tools.
Replacement Media & Parts
Pro tip: The Fleck 2510 AiQ's air injection is what makes this system nearly maintenance-free. There's no chemical feed, no potassium permanganate, no chlorine injection. The air bubble in the head oxidizes iron as it passes through, and the Katalox-Light media catches the precipitate. Questions? Call 800-460-5810 or text Aidan at 443-277-2204.

The Complete Iron + Hard Water Solution for Mid-Size Well Water Homes
2.5 cu ft Katalox-Light Iron Filter + 48,000 Grain Fleck 5600SXT Softener
Well water with both iron and hard water needs two systems. A softener on its own handles only low levels of iron, and an iron filter does nothing for hardness. This package pairs the Fleck 2510 AiQ with Katalox-Light (removes up to 30 ppm iron, 15 ppm manganese, and 10 ppm sulfur with no chemicals) with the Fleck 5600SXT 48,000 grain water softener (10% crosslink resin, demand-based regeneration). The iron filter goes first and protects the softener resin from iron fouling, and the softener handles the scale and soap problems the iron filter can't touch.
The 2.5 cu ft iron filter gives more flow than the 1.5 and needs about 10 gallons a minute from the well to backwash. This package is sized for 3 to 4 people on water up to about 15 grains of hardness; for five or more people, or harder water, choose the 2.5 cu ft + 64,000 grain package. Free shipping to the lower 48 states, 5-year valve warranties, 10-year tank warranties, and tech support from Aidan 7 days a week.
