I have been using Cidex(it comes with an activator on top, throw that away, DO NOT USE!) from a local source for about a month now. I have to say that it is very similar if not the same as Excel. The gallon I purchased lists the solution at 2.4% Glutaraldehyde and 97.6% inert. I can say that I have had no problems with it so far, and has done a great job in my tank. Mostly for a algaecide. As far as long term effects on humans- I would not mess with the 50/50, 25/75 mixture. I am going to stick to the low percentage Cidex(which is no different than Seachems Excel), and I would recommend doing the same for everyone else. Its too risky to try and dilute yourself. :icon_excl

Flourish Excel is a 2.5% solution of Glutaraldehyde.

So one link you claim is 2.5% the other clearly states and is correct(1.5%).

That not what I claim. That is what Seachem Claims. It was on there MSDS sheet at one time. I am just adding some info so others can decipher for themselves. And yes someone on the indian forum did some testing and supposedly came up with 1.5%. Take it as you will, as I believe the 1.5% is the correct percentage. Just trying to help. roud:
