Fluval Sea CP4 Wave Maker - Space-Saving Circulation Pump for Freshwater & Saltwater Aquariums

Overview

The Fluval Sea CP4 Wave Maker is a compact, high‑performance circulation pump designed to fit neatly in tanks up to 90 gallons. Its space‑saving form minimizes intrusion while delivering a broad, ocean‑like current that helps keep your water moving smoothly.

Natural Flow Simulation

By creating dynamic wave‑like currents, this pump mimics reef and river flows. The result can be a more natural environment for fish, corals, and plants, potentially supporting better oxygen exchange and consistent water movement.

Adjustable Output and Easy Setup

The 270° adjustable nozzle lets you direct flow precisely where it’s needed, reducing dead zones and enhancing overall filtration efficiency. Quick mounting with a secure suction system makes installation flexible and repositioning simple.

Efficiency, Durability, and Compatibility

Designed and manufactured in Europe, the CP4 emphasizes quiet operation and energy efficiency while remaining compatible with both freshwater and saltwater setups. Its durable build is suited for continuous operation, helping you maintain steady water movement over time.
