What happens to the dead stuff if the unit works? Doesn't the fuel system still require the same filters to remove dead bugs as live bugs? Whether the fuel system uses Algae-X or not, I would expect any bugs trapped in the filters to die because the water/fuel interface is no longer available. If Algea-X claimed to make algea/bacteria disappear I would be alot more interested in their unit. Keith Christianson M/V Tussler
