Re: [GSAS-Member] Anyone use a UV sterilizer?

[Algae Magnet <algaemagnet@gmail.com>]

I have a good sized UV steralizer on a 45 gallon acrylic tank.  I don't have
a comparable control tank, but relative to my other stetups, I see no
appreciable difference in algae control (green spot or otherwise).  I
installed it hoping that it would reduce the chance of disease and deter
some algal growth, but relative to the other tanks I have, I could not claim
a significant difference.  My UV sterilizer is installed inline with the
output from a Magnum 350 that I also use as a CO2 reactor.  To date, running
with or without UV doesn't seem to show any direct correlation to algae
growth.  From my limited experience, consistent CO2 and fertilizer dosing
appears to correlated to minimal macro algae growth and reduced lighting
interval appears to be correlated to reduced green spot algae.

I will watch with interest to see what others have deduced from their usage
of UV.
