Oase Biosmart 36000 (Biotec 10.1)

The Biosmart 36000 (formerly Biotec 10.1) is the latest generation of a tried and trusted family of gravity filters. High quality materials and optimised functional design combine to achieve superb pond cleaning results. Water is fed into the filter where mechanical media remove solid waste through different grades of filter foams. Biological cleaning utilises beneficial micro-organisms that convert harmful ammonium/ammonia via nitrite to nitrate and finally into harmless gaseous nitrogen. All Oase Biotec filters accept direct connection of Bitron Ultraviolet Clarifiers.

I hook the water hose to a faucet coming off a line on my pump so I'm flushing with pond water and not house water.

When you flush the filter with the garden hose attached surely the tap water would then kill of all the beneficial bacteria?

[@KenyonHopkins]

Correct. It would not be recommended to use treated tap water to flush your filter.

I was considering this filter, but it looks like it only has filter foam & no media inside for the bacteria to grow on?

[@Convantol]

Bacteria also grow on the foam, bacteria actually grow everywhere.
