I am from Mexico city! I really don't know the place you are telling me, the eje 1... The other one, the market, I do know. It's amazing how much s*** they carry there, but to be honest I dont trust that place too much. I'm really interested in starting a reef system, currently I only have FW tanks, planted and community. Bue I like to do a lot of research beforehand, and I really appreciate any help I can get form this forums. ABout the live rock, I assume you got that in Mixuca market near the airport? Or where do you mean? Thanks a lot for the replies! Saludos!!
