I'm not sure if this is the right forum--I will let the mods decide--but I just got a phone call from some guy in Hawthorne named Randy. He first tried to sell me an acrylic tank but then pitched me this idea of a system where no water change is necessary---ever. But he couldn't tell me about it, he would either build me a system or let me see his for a fee of $50. I am wondering if anyone else has had dealings with this Randy. This whole thing sounds shady and too good to be true.
