Wow...I am new with these Algae-X things, my boat came with them and I'd never seen them before. Very interesting discussion, seems like the general concensus is, "Give me a break Batman!". So I guess that applies to DeBug since they employee the same technology.
Thanks for the input....I've got a guy trying to tell me that Algae-X doesn't work but DeBug really works. So I guess I'll show him the plank and tell him where to walk. I already have Racors on both engines plus the normal spin-ons after that, plus a West Coast
Filter polishing system, so I think I'm set without all this stuff. I will leave the Algae-X in place since they are already piped in, but won't replace 'em.
