Frequently Asked Questions

What is a fixed flow pump?

A fixed flow pump delivers a set, consistent flow rate rather than an adjustable range. This makes it well suited to systems where a specific GPH is required to maintain nutrient delivery schedules or filtration rates.

How do I install this pump inline versus submersible?

For submersible use, place the pump directly in the reservoir. For inline use, mount it outside the reservoir and connect the included fittings to your intake and outlet tubing. Both configurations use the same pump body.

Is this pump safe for saltwater?

Yes — the oil-free ceramic shaft impeller is compatible with both fresh and saltwater applications. There is no oil to leach into the water column in either environment.

What accessories are included?

The pump includes a variety of attachment fittings, a strainer, and a foam pre-filter for immediate use. These let you set up submersible or inline operation without buying separate parts.
