JBJ Reaction Pro 2 Canister Filter RPC-175

Description

JBJ Reaction Pro 2 RPC-175 Canister Filter — High-Capacity Multi-Stage Filtration for Large Aquariums

The JBJ Reaction Pro 2 RPC-175 is a premium external canister filter engineered for freshwater and saltwater aquariums up to 175 gallons. Delivering 530 gallons per hour through a comprehensive 4-stage filtration system — mechanical, chemical, biological, and UV sterilization — the JBJ Reaction Pro 2 RPC-175 provides the complete high-capacity filtration solution that large aquariums demand. The integrated 13-watt UV-C sterilizer delivers significantly greater pathogen neutralization capacity than the RPC-100’s 7-watt unit, appropriate for the larger water volume of 100–175 gallon systems. The JBJ Reaction Pro 2 RPC-175 features the same Auto Prime Button for mess-free startup and Quick Connect Valves with manual taps for tool-free maintenance that define the entire Reaction Pro 2 line.

Key Features of the JBJ Reaction Pro 2 RPC-175

• 530 GPH flow rate — powerful circulation for aquariums up to 175 gallons; thorough water turnover for large freshwater, saltwater, and reef systems
• 4-Stage filtration — mechanical sponge, activated carbon chemical, ceramic ring biological, and UV sterilization combined in a single high-capacity unit
• Auto Prime Button — instant siphon on startup; completely mess-free setup and restart every time
• Quick Connect Valves with manual taps — shut off and isolate the filter for maintenance without disconnecting tubing or draining lines
• Compatible with freshwater and saltwater aquariums — suited for large community tanks, planted tanks, FOWLR systems, and reef aquariums

JBJ Reaction Pro 2 RPC-175 — 4-Stage Filtration System

Stage 1 — Mechanical Filtration

Water enters via the intake strainer and passes through a large sponge that captures particulate matter, detritus, and suspended solids before they reach the chemical and biological media stages.

Stage 2 — Chemical Filtration

Water passes through activated carbon that removes dissolved organic compounds, tannins, odors, medications, and discoloration — maintaining water clarity and chemical stability in large-volume systems.

Stage 3 — Biological Filtration

Water flows over ceramic rings providing extensive surface area for beneficial nitrifying bacteria colonization — supporting a stable nitrogen cycle across the larger water volume of 100–175 gallon systems.

Stage 4 — UV Sterilization

Water passes through the integrated 13-watt UV-C sterilizer chamber — neutralizing free-floating bacteria, parasites, algae spores, and pathogens. The 13-watt output is appropriately scaled for the JBJ Reaction Pro 2 RPC-175’s larger capacity, delivering effective sterilization across a higher volume of water per pass than the RPC-100.

Setup and Maintenance

The JBJ Reaction Pro 2 RPC-175 is designed for straightforward installation and low-maintenance operation. The Auto Prime Button creates an instant siphon on startup — fill the canister, press the button, and the filter begins circulating immediately. Quick Connect Valves with individual manual taps allow independent shutoff of intake and return lines for maintenance isolation without disconnecting tubing. Easy-remove basket trays provide direct access to all four filtration stages.

RPC-175 vs. RPC-100 — Choosing the Right Model

For aquariums under 100 gallons, the JBJ Reaction Pro 2 RPC-100 delivers 360 GPH with a 7-watt UV sterilizer at a lower price point. The RPC-175 is recommended for aquariums between 100 and 175 gallons, or heavily stocked tanks under 100 gallons that benefit from additional filtration capacity.
