Spring pond opening and start-up

After a Missouri winter, the pond usually has leaves on the bottom, a pump sitting idle and a filter with no bacteria colony. A spring opening gets everything running before algae season.

Signs it's time

  • Leaves and debris that sank over the winter
  • Pump, waterfall or UV light shut off for the season
  • Netting or a de-icer still in place
  • Fish becoming active again as the water warms up

What the visit usually involves

  • Removing netting, leaves and winter debris
  • Reinstalling or restarting the pump, waterfall and UV clarifier
  • Cleaning and restarting the filter, and adding beneficial bacteria
  • Checking for winter damage to the liner, plumbing or edges
  • A basic water check, plus advice on when to start feeding fish again

Every pond and every pro is a little different. The pond professional you're matched with will explain their own process and price before any work starts.

Have this ready when you call

  • What equipment you have (pump, skimmer, filter, UV), if you know
  • Whether the pond ran all winter or was shut down
  • Anything that looked wrong last fall

Questions

When should I open my pond in St. Louis?

Most people start when the water warms into the 50s, which around St. Louis is often March or April, depending on the year. Booking a little ahead helps, because spring is a busy time for pond pros.

Can a spring opening and a full cleanout happen together?

Often, yes. Spring is a common time for a full cleanout, since the fish are still sluggish and the muck from fall is all there. Mention it when you call.
