JBJ OceanStream Nano Stream Pump WM-3E

Description

JBJ OceanStream Nano Stream Pump WM-3E — Powerful 800 GPH Circulation for Nano and Small Aquariums

The JBJ OceanStream Nano Stream Pump WM-3E is a compact, high-efficiency 800 GPH circulation pump engineered for freshwater and saltwater aquariums up to 30 gallons. The JBJ OceanStream Nano Stream Pump WM-3E delivers powerful, wide-pattern water circulation through JBJ’s innovative PaddleDisc™ impeller — a design that diverts water to the perimeter of the housing rather than projecting it in a narrow direct stream like traditional propeller-based pumps. The result is maximum random flow in wide circular currents that provide thorough tank circulation and gentle, natural water movement without creating a directed jet that can damage corals or stress fish placed in its path. The magnetic mount with articulating pivot ball secures the pump to aquarium glass up to ½ inch thick and allows precise directional adjustment without removing the pump from the tank. The JBJ OceanStream Nano Stream Pump WM-3E is fully compatible with the JBJ OceanPulse Wavemaker Duo — connect up to two units to the wavemaker to create programmable alternating flow cycles that mimic natural ocean current patterns.

Key Features of the JBJ OceanStream Nano Stream Pump WM-3E

• 800 GPH flow rate at 3 watts — powerful circulation for its size class; highly energy-efficient at maximum output
• PaddleDisc™ impeller — diverts water to the perimeter of the housing for wide circular random flow rather than a narrow direct stream
• Coral-safe random flow — wide circular currents provide gentle water movement that does not harm corals placed directly within the flow path
• Magnetic mount with articulating pivot ball — secure glass mounting up to ½ inch thick; precise directional adjustment without removing the pump
• Compact redesigned housing — 4″×2″×2.5″ profile fits ideally in aquariums up to 30 gallons without dominating the aquascape
• 70-inch cable length — extended cable provides flexible placement options without requiring an extension cord
• OceanPulse Wavemaker compatible — connects to the JBJ OceanPulse Wavemaker Duo for programmable alternating flow cycles from 10 seconds to 6 minutes
• Compatible with freshwater and saltwater aquariums

PaddleDisc™ Technology — Why It Matters

Traditional aquarium powerheads and circulation pumps use propeller-based impellers that project water in a concentrated, high-velocity stream. This narrow jet flow can create dead spots in areas of the tank not directly in the flow path, and can damage corals, sea fans, and delicate invertebrates placed anywhere near the outlet. The JBJ OceanStream Nano Stream Pump WM-3E’s PaddleDisc™ impeller works differently — it diverts water outward to the perimeter of the housing, creating a wide, circular, lower-velocity flow pattern that reaches more of the aquarium volume simultaneously. The result is more thorough, even circulation with gentler flow that is safe for corals, anemones, and invertebrates while still delivering 800 GPH of total water movement.

Magnetic Mount — Secure Positioning Without Suction Cups

The JBJ OceanStream Nano Stream Pump WM-3E eliminates the unreliable suction cup mounting of older powerhead designs entirely. The powerful magnetic mount secures the pump to aquarium glass up to ½ inch thick with a strong, stable hold that does not loosen over time or fail unexpectedly. The articulating pivot ball allows the pump’s outlet to be directed precisely — up, down, or to either side — with a simple adjustment from outside the tank. No tools, no water changes, no disturbance to the aquascape required.

OceanPulse Wavemaker Compatibility

The JBJ OceanStream Nano Stream Pump WM-3E is fully compatible with the JBJ OceanPulse Wavemaker Duo. Connect up to two OceanStream Nano pumps to the wavemaker to create programmable alternating flow cycles that switch between pumps at intervals from 10 seconds to 6 minutes — simulating the natural tidal surge and wave patterns that reef aquarium inhabitants thrive in. This alternating flow pattern reaches all areas of the aquarium in sequence, eliminating dead spots and providing the dynamic water movement that promotes coral health, fish activity, and efficient gas exchange.

Setup and Installation

The JBJ OceanStream Nano Stream Pump WM-3E installs in seconds. Place the magnetic mount on the outside of the aquarium glass and the pump on the inside — the magnets draw together through the glass and hold securely. Use the articulating pivot ball to direct flow as desired. Plug in and the pump begins circulating immediately. No priming, no tubing, no plumbing required.
