Re: [APD] EHEIM diatom Filter/ Bacterial Bloom
Ahhh! I see where my confusion lies now. I assumed the UV steriliser was
just like any other tube lamp which you would put on top of the aquarium,
but correct me if I am wrong, the UV steriliser is a self-contained unit
which connects to a in or outflow hose, and the sterelisation happens there?
Sharon, while I do not fully understand the nature of diatomaceous earth or
filters (learning quite a bit now though!), I am a bit taken aback by the
seemingly unnatural amounts of hostility you hold towards Scott.
Only the water passing through the lamp is irradiated,
along with whatever is in the water passing through. With
the proper flow rate, the water and the stuf in it is
exposed long enough that it is killed or damaged
sufficiently that it cannot reproduce. The effect is
lasting on bacteria and algae that pass through the UV but
the water itself is not changed.
I may be mistaken here (And I'm sure I'll be corrected if I am.), but I
think that the reason that a UV filter doesn't hurt plants/fish/shrimp is
that they don't get pumped through the UV filter and therefore are not
exposed to the UV rays...
