Frequently Asked Questions

Can this pump be used in salt water?

No — this pump is rated for fresh water use only. Do not use in salt water or marine applications.

How does a waterfall pump prevent algae?

Moving, aerated water disrupts the still conditions that algae prefer. Consistent circulation also helps distribute beneficial bacteria throughout the pond.

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.

What size pond or waterfall is this rated for?

Match the pump's 3700 GPH output to your waterfall width and head height. A general guideline is 100 GPH per inch of waterfall width at the spillway.
