 The Aquadyne Bead filters have been engineered specifically for koi ponds and water gardens. The Aquadyne is available in four sizes, the secret to the Aquadyne bead filters, is that they feature a central diffuser column that reduces internal friction loss.
The Aquadyne Bead filter design has no internal elbows, and allows maximum water flow under the most abusive feeding practices. The Aquadyne Bead filter supports colossal amounts of fish AND delivers GIN CLEAR water, without flow restrictions.
We cannot foresee a more perfect bead filter being introduced than the Aquadyne Bead filter . The best part of the Aquadyne is it's unique plumbing which allows water to bypass the filter completely, for medication purposes. The rinse cycle in the Aquadyne is an absolute must, as there is absolutely no "brown dirt cloud" after a backwash.
