XStream 3500 Wave Pump (925 GPH) - Sicce

The Sicce XStream 3500 delivers 925 GPH of flow from a housing that measures just over two inches in each dimension, making it one of the more space-efficient wave pumps available at this flow class. At 4 watts, the power draw is low enough that it can run continuously without meaningful impact on operating costs. Despite its compact footprint, the pump is built around components typically found in larger, more expensive units — ceramic bearings, a self-cleaning impeller, and a magnetic mount assembly with integrated vibration dampening.

The magnetic mount is rated for tank walls up to 5/8" thick and uses a silicone spacer to isolate the pump body from the glass, reducing the buzz and rattle that plague cheaper magnetic-mount pumps. The O-ring mount serves the same purpose on the impeller side, keeping mechanical noise from transmitting into the water column. The pre-lubricated, self-cleaning impeller reduces the frequency of manual cleaning intervals and extends bearing life under continuous saltwater exposure.

The XStream 3500 ships with a spiral cord protector that keeps the power cable tidy and reduces stress at the connection point — a detail that matters in a wet environment. The 7.2-foot cord provides enough reach for most sump-based setups without requiring an extension.

This pump is a practical choice for nano and mid-size reef systems where low profile and quiet operation are priorities. It is not a controllable pump and does not integrate with aquarium controllers; flow is fixed at the rated output. Hobbyists running larger tanks or needing variable flow profiles should consider a DC wave pump instead.
