I love Liveaquaria.com! Ok, so I haven't actually ordered anything from them, but I have ordered lots from Drs. Foster & Smith (partner site) and they are the best. A couple years ago I bought a heater from them and tested it in a bucket to see how accurate it really was. I had problems with the first 2 heaters and within 2 days I got a packaging slip to send them back. The third one works perfectly and am still using it. Amazing customer service.
