This is a beautiful, contemporary pond. Simple but very effective.
Dave only collects high quality Koi and they grow very well in this system. In 4000 gallons there are only 8 pieces in there.
The smallest Koi in there are Nisai, and the largest is over 70cms.
An excellent collection of Koi.
The pond is fed via one Bottom Drain and feeds into a Sieve, and then returns through a Ultra Bead 60 with Micro K1.
There is also a 4 tier Shower on the pond too.
