After all the things I head about the algae frees, I think I'm sold. :mrgreen:Unarce":2x3skgfj said:Also using an Algae Free Hammerhead. I get great muscle definition in my arms with this one. When I decide I want to build more muscle mass, I'll try the Tiger Shark.
Seriously, though. The Algae Free magnets get the job done. The pads are easy to replace, and the customer service is great. When my inner magnet stopped floating, Mark sent me a replacement right away.
