from what i read ffoeg doesn't use gluteraldehyde he uses molasses

Maybe they can use it and taste it themselves, then tell the rest of us what it taste(burns like hades) like

Only a dolt would even suggest tasting it/let alone taking a big wiff.

Read the MSDS on gluteraldehyde..
Reduced carbon such as sucrose can be used by plants, eg in Tissue culture, and survive a long time without photosynthesis, but adding sugar to an aquarium is not even remotely close.

Anyway, this thread is about gluteraldehyde/Excel, Easy Carbo etc.
It can be DIY'ed and folks have done it.

Personally, I like CO2 gas, it's easier and dose the job better.
Excel is useful for folks having troubles with CO2, or an algae issues, which is also a CO2 problem typically. And perhaps a few that like slower growth than CVO2/low light, but more than non CO2/carbon enrichment.

Works well for smaller tanks etc.
The product is very toxic, I'm even wondering if folks should even use it for aquariums..........the vapor is none too good.

I think my point is long term exposure risk are not tested for this use for humans.

If you use some, here and there, have a small tank, good ventilation in the home, not an issue. If you have a tiny room without much circulation in the air, dose 2-4 tanks daily.........sleep in there, etc..........

I have 5 good sized tanks, but do not use it daily for such reasoning.
But I understand risk assessment better than most aquarist.

Having said that, I'll go take my chances now on the I80/101 drive O death and carnage:icon_mrgr

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%).
