Evidently does what it claims to do and am glad about that! 8/19/2012
I've been using this regularly since 1999 and evidently it does what it claims to do for me because I always have healty fish and tanks.
The price here is great too. I paid a lot more at a popular brick and mortar store because I didn't want to wait.
There isn't much to do with it. Measure and put in your tank a few times every few days when first setting up and then weekly. Your fish will benefit from it. Think of it as acidolphilus for your finned friends.
