Re: [APD] excel
I don't know about a complex sugar but I am curious to know if anyone has
tried or has anymore knowledge as to if Glutaraldehyde can be used for
Polycycloglutaracetal (Excel).
I found a 50% / 50% Glutaraldehyde / water solution of 100ml for $35.
Here is a post from another forum:
here's my friend's reply:
"Actually I'm using glutaraldehyde. Both polycycloglutaracetal and
glutaraldehyde are ingredients in Excel (from what little Seachem is willing to admit)
and from my reading they may have similar effects, namely as a
photosynthesis precursor and an algaecide. I got the glutaraldehyde from my Vietnamese
friend who purchased it in a 50% solution (the highest concentration available
from what I've been able to determine) from a chemical supply company. It is
similar to formaldehyde and is used commercially as a fixative and
disinfectant. The 50% solution is some pretty potent stuff - I only add ~1 mL three
times a week to my 125G and it has pretty much wiped out any sign of algae with
no ill effects on the fish.
I haven't checked around to see where it is sold but I'd be willing to bet
it is available online somewhere. I would recommend extreme caution in using
it. I've heard that it can cause allergic reactions in some people so even
taking a whiff of it would be a bad idea. I keep mine refrigerated to prevent
any possible chemical breakdown."
I got to see this tank a week ago, and it is, in fact, pristine and
beautiful.
Here is what _Wikipedia_
(http://www.answers.com/library/Wikipedia-cid-1624706334) had to say about it:
Glutaraldehyde is a colourless liquid with a pungent odor used to _sterilize_
