BLOOMFIX Replacement Mineral Cartridge for 7,500–20,000 Gallon Pools — Blue, Up to 6 Months, Fits Pump or Skimmer Baskets

BLOOMFIX replacement mineral cartridge is a drop-in pool media made to reduce contaminants and help maintain clearer, softer water for pools holding 7,500–20,000 gallons for up to six months when installed in a pump or skimmer basket.

This cartridge is a low-maintenance supplementary filtration media designed for both above-ground and inground pool systems sized between 7,500 and 20,000 gallons. It works alongside your existing filter and sanitizer by releasing mineral-based agents into the circulation, offering a passive way to support water clarity and comfort without changing plumbing. Installation is straightforward—place the cartridge into the pump basket or skimmer basket and replace it according to pool usage and label directions.

How will this cartridge fit into my current pool setup?

The BLOOMFIX cartridge is compatible with most common pump and skimmer baskets, so no tools or alterations to plumbing are required. It acts as an add-on media that works in tandem with your pump circulation and primary filter to distribute minerals evenly through the water column.

• Fits pump or skimmer baskets—simple drop-in placement
• Works with both above-ground and inground systems
• Designed for pools 7,500–20,000 gallons capacity

What maintenance and lifespan should I expect?

When used according to instructions, each cartridge provides measurable benefit for up to six months, though real-world duration varies with pool use, weather, and circulation. Replace the unit at the end of the recommended period or sooner if physical degradation becomes visible.

• Typical service life: up to six months per cartridge
• Monitor by visual check and pool performance
• Replace sooner after heavy bather load, storms, or extended warm weather

What tangible results can I expect after installing it?

The cartridge releases mineral elements that support clearer-looking water and a more pleasant swim feel when working alongside your regular sanitizer. It does not replace the need for pH checks, chlorine/bromine dosing, or standard filtration, but it can reduce appearance of cloudiness and support water comfort.

• Helps reduce visual cloudiness when used with filtration
• Contributes to a smoother swim feel and reduced eye irritation for some users
• Compliments existing sanitizers—keeps routine chemistry unchanged
• Passive operation—no pumps or electricity required beyond your system

Who is this product for? Pool owners who want a low-effort way to supplement their existing water care routine will find this BLOOMFIX cartridge useful. It’s suited to backyard pools between 7,500 and 20,000 gallons—both above-ground and inground—and to people who prefer an easy, no-plumbing-additions solution to help maintain clear, comfortable water between their regular chemical and filtration maintenance tasks. If you run frequent swim sessions, live in warm climates, or want an extra layer of water quality support without changing your sanitation program, this cartridge is a practical add-on.
