“Wow, this is a lot different than what our last guy did,” Valerie points out. Tom nods in agreement, but he wonders why this process is better and what the other steps actually do differently.
The couple scrolls down to find out why these spring cleaning steps for koi ponds are different.
Moving the fish should be done no matter what process is being followed. Drain some of the water into a separate tub (put in a shady spot) and then move the fish to the tub. Using the water they live in is best so they aren’t shocked by different water.
“I didn’t know that about the water, that’s good to know,” Tom notes.
Once draining the water is done you can use it to flush the muck, algae, and anything else out of the cracks and hard to reach places.
Pressure washing the rocks helps remove the scum and other things harder to scrub off. You don’t want to get everything off because that can hurt the pond ecosystem. Pressure washing too close can remove the beneficial bacteria (and all of the algae, which some need to be left).
“Do you really need some algae left? I thought that was bad for ponds,” Valerie questions. “Well, if some algae are in Mother Nature’s ponds then I guess some should be in ours,” Tom answers.
With the pond drained it’s easier to check on any additions like auto-fills, IonGens, lights, etc. It’s also a great time to install any additions you may want.
After that comes refilling the pond, treating it for the fish if needed, and then properly reintroducing them (you don’t just put them in, it’s not good for them).
“Huh, I wonder what the proper steps for reintroducing fish are?” Tom wonders.
Valerie suggests they save that question for another time and focus on finding someone to spring clean their koi pond. Tom agrees and they start talking about whether to keep looking or not.
