It’s Dirt Dirty

“You’re right, it really is that dirty,” sighs Michael.

Jennifer sighs back. “How’d it get like this?” Michael shrugs. “Not too sure. My guess is that it’s finally been long enough to where this kind of thing just happens. You know, like how cars just get dirty.”

Jennifer nods thoughtfully. “That’s a pretty good analogy hon. Looks like we need to contact our pond contractor to clean it up. For how much a koi pond costs we need to keep it clean and looking good.”

Michael gets his phone out. “First, I want to see how they’re going to clean it. I heard you can either drain it or not and I want to know which they do.” He starts looking it up on Google.

Here’s what he finds:

The Importance Of These Steps

Draining. Draining the water lets us do a deeper and better clean. We can more easily find problems with additions as well as remove debris, algae, and muck. We don’t remove all of it because it’s still part of the pond ecosystem.

Moving fish. We use a tub with their pond water so they don’t go into shock. Fish are sensitive to the water they’re in. New water has a different feel and makeup, so it can cause them to go into shock.

Removing debris. Algae, leaves, sticks, and other things can fall in and turn into muck. We remove it so you can see the beautiful rock bottom of your pond.

Flushing and power washing. This helps remove more muck on the sides, bottom, and rocks. Your pond will look spick and span afterward!

Clean filters. We want to make sure your pond can continue to clean itself and keep the water clear. Cleaning the filter units will help with this.

Checking additions. Bulbs can burn out and other additions can have technical problems. We want to make sure they’re in tip-top shape so you can keep enjoying your pond to the max.

Trim plants. Plants can get out of control and start looking bad or taking over your pond. We’ll get them back to how they should be.

Treat the water. We need to make the water suitable for your fish.

Slowly introduce fish. Throwing your fish into new water can cause them to go into shock. The best method we’ve found is to put them into a bucket, set the bucket into the water, and splash some new water in. Do this every so often for 10 to 15 minutes. Then, let them out.
