Hi Coler, you tried this one?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.
