no, one day i just notice a pile of scum flotting on top of the nozzle. So after watching it for a half hour and then crying for a half hour i put this post up. They called me once and i was not home. They told me to send it back and they would send me a new one. That is fine and dandy but i need to get back up and running as this is my entire current system beside my protein skimmer. I e-mailed them if they could send me a new one and i would even give them a credit card # to hold onto for security. No response.
