How to Install Up-Flow Filters for a Koi Pond

Up-flow filters keep the water clean and clear in your koi pond. They're easily hidden as waterfalls or they can be completely submersed and covered in plants. Up-flow filters also keep harmful chemicals and debris out of the water. Follow these steps to learn how to install up-flow filters in your koi pond.

Difficulty: Moderately Easy

Instructions

1. Select the style of up-flow filter you want to install in your koi pond. There are several sizes available ranging from 10 to 20 inches wide with smooth or turbulent flows.

2. Decide where you would like to install the up-flow filter in your koi pond. You can install it on the edge of the pond or you can put it in the center, surrounded by river rocks or vegetation.

3. Attach the pre-filter screen to the pump if your model includes one. The pre-filters prevent large debris from clogging up the pump.

4. Secure all necessary tubings to the pump. Attach the other end of the tubing to the filters and secure with hose clamps.

5. Level the ground where you will place the up-flow filter. Place the filter and plumbing parts in place and turn the pump on.

6. Check your cleaning indicator on your up-flow filter periodically to see if it needs attention. If your filter is dirty then your koi pond may have contaminants.

Tips & Warnings

• Allow the up-flow filter to run for at least 24 hours before introducing your koi into the pond. This will allow all harmful contaminants to be removed.
• Even if your water is clear it doesn't mean it's clean. It can still contain toxins that are fatal to your koi.
