Many years back there was a post about using Dishwasher powder to soak your catridge filter. I had posted the ingrediants listed on a bottle of cartridge cleanser and a few of the chemistry knowlegable replied how it was the same stuff in dish washer powder. Anybody know what ingrediants to look for when I'm buying the powder? Just fought off a nasty batch of algea and the filter just wont come clean. I want to soak it. It's only a month old and I don't feel like buying a new one already.

Thanks
