Yes, I use Metricide 14 Day. Works great and a better value. Not only is it cheaper on a per volume basis, it is also stronger so you don't need to use as much. If you go that route don't add in the Activator that comes with it. Just throw it away.
Also, the active ingredient in Excel is glutaraldehyde. So Metricide is exactly the same stuff. But, IIRC, Excel is 1.5% glut whereas Metricide is 2.8%.
