Fountains questions, answered by experts

How many fish can call your pond home depends on the volume of the pond and the fish size. Your pond's filtration system also influences the number of fish that will thrive in a pond. A general rule of thumb is to have 1 inch of fish for every square foot in a pond that's 2 feet deep. Another rule of thumb you can follow is to have one koi fish for every 200 gallons of water or two goldfish for every 200 gallons.

When deep cleaning your koi pond, transfer fish to a clean, uncontaminated container at least one foot deep, like a large bucket, tub, or kiddie pond. Fill the container with their existing pond water to avoid shocking them, and place the container in full or partial shade. When it’s time to reintroduce them into the pond, slowly add the new water to the container before adding the fish and container water back into the pond.

You have several options for your pond by getting your yard ready for the winter. You can winterize your koi pond by ensuring it’s at least 5 feet deep so it doesn’t freeze completely, installing a pond heater or aerator and having it run at all times, and installing a deicer if temperatures are dangerously low for an extended period. You can also choose to shut down your pond for the winter by removing all the wildlife in it and bringing it indoors, cleaning out the filter and pump, and then covering the pond with a tarp.

A good rule of thumb is to change 5% to 15% of your koi pon’s water every week. Partial water changes help keep your koi healthy, and replacing small amounts at a time prevents causing stress for the fish.

Natural swimming pools are designed to deter pests, including mosquitoes. While any body of water can potentially attract pests, the natural filtration system keeps the water clean and constantly moving. Mosquitoes specifically are attracted to standing water, so the continuously circulating water in a natural pool makes it an inhospitable environment for them.
