Can't explain why, but the 9 watt sounds better to me. More power! <tim allen grunting sounds! ;)>

Depends on the type of bacteria. They can't make the claim that it will kill all types of "harmful bacteria". Most vegatative cells are very susceptible to UV, but spore formers such as Bacillus sp. are very resistant. But, if it is a bacterial bloom you're experiencing, then I doubt they're "harmful bacteria" at all anyway (your fish are fine right?). If it were me, I'd just keep up my regular tank maintenence and wait it out.
