Frequently Asked Questions

Can this pump be used in salt water?

No, this pump is rated for fresh water use only. Do not use it in salt water or marine applications, as it is not built to withstand that environment.

How does a waterfall pump help prevent algae?

Moving, aerated water disrupts the still conditions that algae prefer to colonize. Consistent circulation also helps distribute beneficial bacteria throughout the pond, supporting a more balanced ecosystem.

Is this pump safe for koi and other pond fish?

Yes, the OASE Waterfall Pump is designed to be safe for fish and aquatic plants when used as directed. Its materials are chosen specifically for compatibility with pond ecosystems.

What size pond or waterfall is this rated for?

Match this pump's 2300 GPH output to your waterfall width and head height. A general guideline is roughly 100 GPH per inch of waterfall width at the spillway, so calculate accordingly before ordering.
