Re: [APD] UV Question
Hmm.. I had a quick look around, and so far none of those brands are on
offer in Australia.
Could someone explain this to me... The Aqua Pro series 9 watt is cheaper
than the 6 watt. Ideas why? Is the 9 watt an inferior model? Also, on the
product description, it says that the unit will kill algea growth and
"reduces harmful bacteria". Does this mean that it is not very efficient at
killing the bacteria?
The Rainbow units seem to claim a higher kill rate for a broader range of
Most of the liftime of the bulbs is rated by continual usage, right? So if I
only used the UV striliser periodically when there is a problem, it should
last for several years then, correct?
and some are based on lethality only for algae,
which requires a much smaller exposure than protozoa.
For a 30 gallon tank, 8 or 9 watts should plenty.
The products you mention are very well built but a but
pricey, imo. Consider also the Custom Sealife, Tetra's
unit, and the relatively new Coralife models.
