well so says the bottle.
Prime...all the way!
Definitely change to Prime. I used to use aquaclear too, until I found a supplier who ships to Ireland (not available in the shops here).
It goes a lot further, and it does more too. You will save money, and you have a better product too. Its one of those very rare win win scenarios. There is no downside.
I go through a bottle of prime a month, but I have 8 tanks. Get Prime well worth the value all the way around.
