HydroLogic® BIGboy™ De-Chlorinator & Sediment Water Filtration System - 7 GPM / 420 GPH - 25,000 Gallon Capacity

Extra High-Capacity Inline Water Treatment for Commercial Operations

The HydroLogic® BIGboy™ De-Chlorinator and Sediment Water Filtration System is HydroLogic's highest-capacity inline water treatment solution — delivering 7 GPM (420 gallons per hour) of treated water with 25,000-gallon total filter capacity per service cycle. With 99% chlorine removal and 95%+ sediment reduction, the BIGboy is engineered for commercial growing facilities and high-throughput water treatment applications where the smallBoy and TALLBoy systems can't keep pace with demand.

Inlet and outlet pressure gauges let operators monitor filter condition in real time, and a heavy-duty aluminum wall bracket supports permanent, professional installation for the system's 30-lb weight.

Key Features & Benefits

• Extra high capacity — 25,000 gallons: each service cycle delivers up to 25,000 gallons of treated water before cartridge replacement, reducing maintenance frequency compared to smaller systems.
• 7 GPM flow rate (420 GPH): handles the demanding throughput requirements of commercial greenhouse and hydroponic operations.
• 99% chlorine removal, 95%+ sediment removal: a pleated, cleanable sediment filter and carbon block filter work in separate housings for staged, thorough water treatment.
• Inlet and outlet pressure gauges: integrated pressure monitoring lets you track filter condition and identify when servicing is required.
• Heavy-duty aluminum bracket: wall-mountable, rated for the system's 30-lb weight for permanent, professional installation.

Who Should Use This

Designed for commercial greenhouse operators, large-scale hydroponic facilities, and CEA operations that require high-volume, reliable chlorine and sediment removal — particularly as a pre-filter before RO systems or where daily water consumption makes smaller systems impractical.

Compatibility

Connections: 1in inlet/outlet — Replacement sediment filter: HGC741606 — Weight: 30 lbs. Includes 2-stage oversized housings, pressure gauges, wall bracket, filter wrench, and instructions.

Frequently Asked Questions

How does the BIGboy compare to the TALLBoy and smallBoy?

The BIGboy offers the highest capacity in the lineup at 25,000 gallons and 7 GPM, compared to the TALLBoy (7,500 gal, 2 GPM) and smallBoy (3,000 gal, 1 GPM). The BIGboy is for high-volume commercial applications where the smaller systems would require too-frequent cartridge replacement.

How often do the filters need to be serviced?

The system delivers up to 25,000 gallons per filter service cycle. The pleated sediment filter (HGC741606) is cleanable by rinsing with a hose and should be replaced every 6 months, while the carbon block filter should be replaced per its rated capacity.

What do the inlet and outlet pressure gauges tell me?

Monitoring the pressure differential between inlet and outlet gauges indicates filter condition. An increasing pressure differential signals the sediment filter is loading up and will need cleaning or replacement soon.

Can this be used as a pre-filter before an RO system?

Yes — the BIGboy is an effective high-capacity pre-filter for commercial RO systems, protecting RO membranes from chlorine and sediment to extend their service life. This pairing is common in facilities running large-format commercial RO.
