Frequently Asked

Answers before
you call.

01

How often does a koi pond need cleaning?

A full drain-and-clean once a year (spring) is plenty for a well-filtered pond. Add spring open + fall close visits for a hands-off season.

02

Do you service ponds you didn't install?

Yes — we service any pond in our Suffolk County coverage area, regardless of the original builder.

03

How often should a pond be cleaned?

A full spring clean-out annually, plus a fall netting and shutdown.

04

Do you offer service plans?

Yes — monthly and seasonal maintenance plans covering filters, water quality, and treatments.

05

What about algae?

We treat the cause — filtration, plants, and circulation — before reaching for chemicals.
