Also check out Jeff at customking. He does nice work. Jeff at lifereef is nice to deal with. I have never had one of his sumps though only the overflow box.
Thanks, Im looking into the LF2 model. My tank will be drilled and with a durso standpipe so that should take care of that gurgling noise. Ive heard good things about the systems particularly the way they are built. Ill keep doing more research on this. Thanks again.
