AquaFX Dicuss 4-Stage RO Light-Commercial 500 GPD System
With Integrated Chloramine Blaster Filters
Meet the all-new AquaFX Dicuss w/ Chloramine Blasters—a light-commercial Reverse Osmosis powerhouse engineered for areas where cities treat water with aggressive chloramines. Standard carbon filters let toxic ammonia gas pass right through, which ruins membranes and ecosystems. This specialized 4-stage system utilizes dual oversized Chloramine Blaster cartridges to completely shatter the chlorine-ammonia bond, delivering a massive 500 GPD (Gallons Per Day) of pure water at standard household pressure—zero booster pump required.
Hand-built in the USA by AquaFX, it is the ultimate heavy-duty solution for large-scale freshwater aquariums, reptile stores, busy households, and high-volume specialty brewing.
Why Choose the 4-Stage Discus w/ Blasters?
- Destroy Chlorine & Chloramines: Features two sequential 10" x 4" Chloramine Blaster pre-filters to maximize contact time and completely neutralize harsh municipal disinfectants.
- 500 GPD on Standard House Pressure: Generates full commercial-scale output at standard 65 PSI—saving you the cost, wiring, and hassle of adding an external booster pump.
- Perfect for Freshwater Aquatic Setups: Eliminates heavy metals, toxic chloramines, and hard water minerals to create a pristine, safe habitat for sensitive fish, shrimp, and delicate planted tanks.
- Ideal for Reptile Misting Systems: Delivers chemical-free, pure water that protects sensitive reptile skin while completely preventing mineral buildup from clogging misting nozzles and staining glass enclosures.
- Specialty Brewing (Coffee, Beer, & More): Provides a perfect, zero-TDS blank canvas that allows brewmasters and baristas absolute control over water profiles for precise ingredient extraction and unmatched flavor consistency.
- Universal Soft Water Applications: Serves as the ultimate high-volume source wherever pure, mineral-free soft water is required—including humidifiers, commercial cleaning, and laboratory hobbies.
- Double the Lifespan, Fewer Filter Changes: The oversized 10x4 commercial canisters hold more than double the media capacity of standard residential filters, meaning longer service life and less frequent maintenance.
- Pro-Grade Monitoring Built-In: An integrated Backlit Dual-TDS Meter gives you real-time water purity readings at a glance, paired with a smooth steel Pressure Gauge for instant system diagnostics.
- Fully Loaded Automation: Comes standard with an Automatic Shut-Off Kit, adjustable flow restrictor, and quick-disconnect check valve for seamless, hands-free operation.
The Advanced 4-Stage Filtration Process
Oversized commercial-grade cartridges systematically break down chemical bonds and strip away dissolved solids:
- Stage 1: AquaFX Premium 1-Micron Sediment Filter (10" x 4") – An ultra-fine mechanical barrier that traps physical debris like rust, dirt, silt, and sand to extend system life.
- Stage 2: AquaFX Chloramine Blaster Carbon Pre-Filter (10" x 4") – The first line of chemical defense, utilizing pressure-treated reactive carbon to actively break apart the stubborn chlorine-ammonia bond.
- Stage 3: AquaFX Chloramine Blaster Carbon Pre-Filter (10" x 4") – A secondary polishing stage providing critical extended contact time to trap residual volatile organics and ensure zero chloramine breakthrough reaches the membrane.
- Stage 4: AquaFX TFC 500 GPD RO Membrane (Made in the USA) – The heart of the system. Forces pre-scrubbed water through microscopic pores to reject up to 99% of total dissolved solids (TDS), heavy metals (lead, copper, arsenic), and complex contaminants.

Important Operational Notes:
- Output ratings are based on optimal conditions: 65 PSI, 77°F, and 250ppm TDS water input over a 24-hour period. Lower source pressure, colder water, or higher baseline TDS will reduce daily output. A high-flow booster pump with 3/8" fittings is highly recommended if your source pressure drops below 45 PSI.
- Retailer Note: If your local fish store (LFS) sells water directly to retail customers by the gallon, we recommend upgrading to our Blue Marlin or Blue Marlin PRO lines for rapid, continuous commercial production.
