I also used to use GSE in my birdies water...But after I tasted the stuff (even diluted) I decided if I wouldnt drink the stuff why would I make them lol...Its disgusting...Poor birds lol..At least its not flavord on top of the already bad taste...like for example when pharmacies flavor different medications or that white barium stuff with lemon or the oh so disgusting cherry flavor. Like who decided that this stuff doesn't taste bad enough without adding a nasty flavor on top of it...LOL (that was random I know)
