I just got my Sequence StingRay pump on Thursday to replace my Amp2100 pump that has lost its seal. Unfortunately it is a bit larger than the Amp and with the female threaded connections I would have to add some connections to it to get it to work with what I have. Either way, it is too big to fit where I have my Amp currently so I haven't had a chance to hook it up and check it out. Probably just save it for my 240g.
