Biozorb was our earliest concept
of pond filtration and has needed little change to maintain
its reputation for economy and effectiveness.
Biofloc performs the same function but has an
outflow near the top which means it can be partly buried
When used with a Hozelock Cyprio
UVC both models carry the Clearwater Guarantee.
Hozelock Cyprio Biomedia is designed to have an enormous
surface area in a small volume and to allow good water
flow through it. Therefore it maximises the number of
beneficial bacteria which live on these surfaces and
the amount of pollutant 'food" which is brought
to them in the water flow.
