When to Clean Your Pond

by Kerri Bailey, The Pond Pad

It’s that time of the year again, when our ponds wake up from the warmth of spring with active fish and budding plants. Now is a great time to take a look and decide what condition your pond is in & what you need to do about it.

Your pond or water feature needs to be cleaned when:

  • There is an inch or more of sludge build up on the bottom and shelves.
  • Excessive algae blooms and filamentous(string) algae problems.
  • Your water is turbid, cloudy and mucky or slimy looking.
  • It’s been more than 3 years since the last complete clean-out.

How often you clean your pond:

  • Typically once a year, or every 2-3 years depending upon your fish load & filtration – heavier the fish load (yearly), smaller fish load & better  filtration (2-3 years).
  • There are always exceptions, healthy water = healthy fish & plants.  Using beneficial bacteria products like Autumn Leaves Digester by Strata, will help maintain the balance by digesting the fish waste & debris that accumulate over time.  Having a veggie filter, bog garden or just a lot of plant coverage will also enhance water quality.  Most algae blooms are a result of excess pond waste, so decrease your waste, decreases the algae.

When to clean your pond:

  • Water features, ponds, etc. with no fish- clean just about anytime of the year.  If there are plants, protect them from the hot sun or cold winds.
  • Typically, ponds with fish, are cleaned in late spring through early to mid summer, weather dependent (around 60 – 80 deg F). Avoid cold days, extremely hot days or when fish are dormant. Fish can die from stress, so be careful with them!
