This fresh water tank is dosed once a week over a month. The algae have hardly changed. However, this was fatal for inversions in the reservoir. For runaway pest slugs, that's not so bad. However, this is not good for shrimp. I'm also having an issue with one of the fish which I think may be related to the shedding but may not be. In general, I'd be very cautious about using this on any tank unless you're willing to drop the entire tank. Only use the last option.
