Pond cleaning in Boise, Idaho

Pond cleaning in Boise is usually a spring job, and it starts when an owner looks into the water and says, "I can't see the bottom anymore." Over a year, leaves, fish waste and dead plant bits sink and break down into a layer of dark muck. That muck feeds algae, clouds the water and uses up oxygen your fish need. A good clean-out once a year resets the pond.

I'm Kabe Hockema, and I do pond clean-outs myself. I build ecosystem ponds with Aquascape components, so I know how each part should look when it's working right. A clean-out is also my chance to spot a worn pump or a low edge before it turns into a bigger problem.

When to clean a pond in Boise

The best time for a full clean-out in the Treasure Valley is early spring, after the ice is gone but before the water gets warm. In most years that falls around March or April. Here's why that window works:

• Fish are still slow from the cold, so they handle the move to a holding tank better.
• The good bacteria haven't fully come back yet, so you're not knocking down a filter at its peak.
• You get a fresh start before summer heat brings on algae.

I avoid full clean-outs in the heat of summer. Warm water and stressed fish don't mix. If a pond needs help in July, I'll do a lighter service instead.

Signs your pond needs a clean-out

• You can't see the rocks on the bottom.
• Muck stirs up in a brown cloud when you put your hand in.
• The water smells like rotten eggs.
• The skimmer and filter mats clog within days.
• It has been more than a year or two since the last full cleaning.

What happens on clean-out day

A typical spring clean-out takes most of a day for a standard backyard pond. Here's how it goes.

Set up a holding tank. Before I drain anything, I fill a holding tank with water from your pond. The fish go into water they already know, with an aerator running and a net on top so nobody jumps out.

Drain and catch the fish. I pump the pond down slowly. As the water drops, I net the fish and move them to the tank.

Remove the muck. I clear the sludge from the bottom and pull out leaves and sticks wedged between the rocks.

Rinse the rocks. I rinse the rocks and gravel with a pressure washer, working from the top shelf down, and pump out the dirty water as it collects. I don't scrub the rocks bare. A little brown film is fine and helps the bacteria come back.

Service the filters. I empty the skimmer, rinse its filter mats, clean the media in the biofalls, and check the pump and plumbing.

Trim the plants. I cut off dead growth and divide plants that have taken over.

Refill and restart. I refill the pond and add a dechlorinator to treat the city water. Then I add beneficial bacteria to restart the filter.

Bring the fish home. I float water from the pond into the holding tank a little at a time so the fish adjust to the new temperature before going back in.

What I won't do during a cleaning

Some cleanings do more harm than good. I don't use bleach or harsh cleaners. I don't leave fish sitting in a small bucket for hours. And I don't clean so hard that the pond has no good bacteria left, which often leads to a big algae bloom a few weeks later.

What drives the cost of pond cleaning

The price depends on:

• Size and depth of the pond and how much water there is to pump.
• How much muck has built up since the last cleaning.
• Number of fish to catch and hold.
• Waterfalls and streams that also need rinsing.
• Repairs or parts I find along the way, like a new pump or filter mats.

I'll look at the pond first and tell you what to expect.

Cleaning, dredging or maintenance

A clean-out handles a lined backyard pond. Larger earthen ponds with deep silt need pond dredging instead. If you want help through the rest of the year, my pond maintenance page covers the summer, fall and winter routine. And if the clean-out turns up a leak or a cracked fitting, I can handle the pond repair too. You can see everything I do with ponds on my pond contractor page, and my broader water features work.
