Johnny, just send Roger Vitko (from Tunze) an email or PM on RC explaining that your 'C' clamp broke. He'll replace it with the new and upgraded style for free. We have two at HOF and they both broke as well. They were replaced for us and for everyone else that has the same issue. Great customer service.
Thanks Russ! He already said he is going to ship me one free.
To whomever, showed an interest in buying, I've decided to keep it for my nano tank, since I'm getting a new clamp free.
Mod, will you please close this thread....sorry guys!
