Get the right size pump for the job. Different pumps are designed to work for different sizes of ponds, so make sure to do the research and find the best size motor for your setup. If you choose a motor that's too small for your pond, you risk burning it up. If you choose one that's too large, you're wasting money and could harm your fish if the suction is too strong. Once you figure out how many gallons your pond holds, choose a model that can completely filter your pond at least once every two hours.
Compare prices. Submersible filters usually start at around $200 and the price goes up depending on the size you need. Free shipping is always a bonus and helps save you money.
Find out what's included. Many submersible filters come with biological media and UVC lamps included, so make sure that you're getting the most out of your money by choosing a model that includes these things free of charge.
Make sure you know how to install it. If the vendor has a customer service line or can have someone come out to your pond and help you with the installation, consider taking advantage of it. Your pond filter is an investment, and the last thing you want to do is fry all your koi on day one.
