HydroLogic® TALLBoy® Dechlorinator & Sediment Water Filtration System - 2 GPM - 5 Micron - 7,500 Gallon Capacity

Inline Chlorine & Sediment Removal for Cleaner Growing Water, 2 GPM

The HydroLogic® TALLBoy® Dechlorinator and Sediment Water Filtration System is a compact, wall-mountable 2-stage water treatment system that removes up to 99% of chlorine and 90%+ of sediment, rust, silt, and volatile organic compounds from tap water — producing 120 gallons per hour of treated water at 2 GPM. With a 7,500-gallon filter capacity per service cycle and a simple garden hose connection, the TALLBoy® improves tap water quality for indoor growing and hydroponic applications without the cost of a full RO system.

At 2 GPM / 120 GPH, this size is built for large-scale reservoir management and high-throughput growing systems — a step up in capacity from the smaller smallBoy® system for operations with greater daily water demand.

Key Features & Benefits

• 99% chlorine removal: a carbon block filter removes chlorine from municipal tap water, protecting beneficial microbial populations and improving growing water quality.
• 90%+ sediment reduction: a 5-micron poly-spun sediment filter captures rust, silt, dirt, and particulates to protect downstream irrigation components.
• Removes VOCs to 5 microns for cleaner, safer growing water.
• 2 GPM flow / 120 GPH output: sufficient for large-scale reservoir management and high-throughput growing systems.
• 7,500-gallon capacity keeps maintenance intervals manageable for medium to large-scale operations, and it works well as a high-capacity pre-filter for Stealth-RO systems.
• Complete installation kit included: 2-stage 20in filter unit, wall-mountable metal bracket, female garden hose connector, brass male garden hose connector, 4ft feed line, 4ft outlet line, filter wrench, and instructions.

Who Should Use This

Ideal for hydroponic growers, indoor cultivators, and greenhouse operators who want to improve municipal tap water quality before it enters their growing system, without investing in a full RO setup. Also effective as a high-capacity pre-filter upstream of a Stealth-RO reverse osmosis system.

Compatibility

Replacement sediment filter: TALLBoy Poly-Spun Sediment Filter (HGC741658) — Dimensions: 12in x 25.5in x 6in. KDF/Catalytic Carbon filter upgrade available.

Frequently Asked Questions

Does this system remove chloramines?

The TALLBoy system is designed primarily for chlorine removal. For chloramine removal, the KDF85/Catalytic Carbon Filter Upgrade provides more effective chloramine reduction; contact HydroLogic for upgrade options.

How long does the filter capacity last?

The system has a 7,500-gallon per-cycle filter capacity. At the system's rated GPH output, this represents roughly the run time before a filter change is needed, though actual capacity in hours depends on usage patterns.

What is included with the TALLBoy?

The TALLBoy ships complete with 2-stage 20in filter unit, wall-mountable metal bracket, female garden hose connector, brass male garden hose connector, 4ft feed line, 4ft outlet line, filter wrench, and instructions. Every part needed for a standard wall-mounted installation is included in the box.

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

Yes — the TALLBoy is an effective pre-filter for Stealth-RO systems, removing chlorine and sediment to protect the RO membrane. Running it upstream of an RO system extends membrane service life.

What replacement sediment filter does the TALLBoy use?

The TALLBoy uses the TALLBoy Poly-Spun Sediment Filter (HGC741658) replacement sediment filter, which should be replaced per the system's recommended schedule. Replacing it on schedule keeps sediment reduction performance consistent.
