Hey guys so I was on ebay and as soon as I clicked on the Aquarium & Fish category this popped up http://cgi.ebay.com/75GPD-FILMTEC-M...709?pt=LH_DefaultDomain_0&hash=item2a10dd4f8d. I think it's a pretty good price and I'll probably order one so if anyone need to replace an RO membrane I'm just passing along the deal.
