Re: [APD] Excel and U.V. light
Interesting item to add to the list, Bill. I have heard
various reports that UV units break down this that or the
other thing. The report most often made that
photo-reduction occurs -- e.g., that UV photo-reduces
typical iron chelators, allowing iron to oxidize to a less
The general point about UV light is certainly valid, scarce
is the evidence that these things actually happen to a
significant degree in aquaria. In aquaria, perhaps the
dosing of the subject chemicals is too frequent for UVs to
make much of a diff.
It would be interesting to hear what SeaChem has to say.
Have you asked them?
A separate but realted issue is whether UV units are really
necessary or especially beneficial for planted aquaria,
other than for occasional use to beat down an attack of
green water or a case of ick.

What? You haven't entered yet this year? The deadline for submissions to the AGA Aquascaping contest is September 15.
Looks like this might be the biggest year ever for Aquascaping Contest entries from countries inside and outside of North America.
So share the fun and show your work.
The AGA's 6th Annual International Aquascaping Contest is open but only for a couple more weeks.
Entries are only $5 and for that half a sawbuck you can have your AGA entry automatically entered in the ADA (Aqua Design Amano) contest for free, a savings in time and shipping costs!
