Zakki Shower Filters featuring Cermedia

The Zakki Shower is one of the most efficient nitrification filters on the market today. It can handle a massive amount of water flow, and is perfect for medium to large koi ponds.


The Zakki Shower can be manufactured into many different sizes to meet your specific water flow needs.  The most common sizes are the full sized version that you see above (49" x 20 1/2" x 20" tall) and contains more than 3 cu ft of Cermedia which provides over 300,000 sq ft of surface area for biological bacteria colonization. Based on nitrification testing this filter can handle 1,400 grams (3 lbs) of 40% protein food per day if the pond water is circulated through the filter twice per hour. The water flow rate should be between 8,000-12,000 gph.  The full sized Zakki Shower comes standard with two 2" pipe nipples for the water inlet and has two 4" pipe nipples on the bottom for water to return to the pond.

There is also the half-sized Zakki Shower that you see above (24 1/2" x 20 1/2" x 20" tall) and contains more than 1 1/2 cu ft of Cermedia which provides over 150,000 sq ft of surface area for biological bacteria colonization. Based on nitrification testing this filter can handle 700 grams (1 1/2 lbs) of 40% protein food per day if the pond water is circulated through the filter twice per hour. The water flow rate should be between 4,000 - 8,000 gph.  The half-sized Zakki Shower comes standard with a single 2" pipe nipples for the water inlet and has a single 4" pipe nipple on the bottom for water to return to the pond.

As you can see the Zakki Showers can also be manufactured with waterfall weirs so they can be placed on the side of the pond.  This makes for a simple plumbing install and a great looking water feature.  They can also be produced with a combination of waterfall weir and pipe returns if you want to have both on your pond.

With this type of shower design the waterfall weir is elevated so that the water level will have to rise up a couple inches before flowing over the weir.  These few inches of extra water depth are what pushes some of the water through the pipe returns and back to your pond.  Each return lines will need a ball valve to control how much water goes through the pipes and how much returns over the waterfall.

No matter what design of Zakki Shower you decide is best for your pond, you need to provide only mechanically clean water to avoid clogging issues with the Cermedia.  The pores in the Cermedia are very small and large particles could end up clogging them which would not allow water to pass through them.  This would lower the effective surface area and less nitrification will take place inside the filter.  We will help you design a complete filtration system for optimum performance and we prefer the use of the Zakki Sieve as a mechanical filter.
