Default Re: glutaraldehyde instead of excel

From googling it (don't take this as gospel), it looks very similar to the stuff that we get. Our solution is 2.5%, and I'm dosing around 1 ml per 5 gallons (some dose more to combat algae, etc). To dose at the same concentration, you'd dose 2.5 / 3.4 * 1 ml = 0.74 ml per 5 gallons.
