ProfiDrum Shower Filter Large with Pipes
The ProfiDrum Bakki Showers add an extra Bio filter for koi ponds which work very well at removing ammonia and nitrites from the water. Bakki showers work best with a large flow of water, the water becomes highly aerated as it flows down through the media gassing off, where as bio chambers ideally require a slower flow to create more dwell or contact time, particularly using plastic media.
Using the right media Bakki Showers can be used as your only bio filter, but most are used as an add onto compliment what you already have.
A ProfiDrum Bakki shower addition will allow you to increase the feed as the koi grow over time.
