btw, one last note, we agree a warranty is a warrant and when you called, we agreed to replace one of the bad pump you mentioned. but when you called, you do not want to exchange for the pump, instead you DEMANDED us to upgrade you to the Cone Skimmer ($589 MSRP). As for the bad pump, it's already been corrected. With the way we operate, if there's a problem, we're not afraid to admit it and will fix the problem immediately. Again, there's no need for all this. good luck to your hobby as this is going to be our last post from us on this matter.
