Thanks Doug, you've always chimed in on my questions and as a long timer lurker, I value your opinion. My tank has been a long time in the making. An inevitable move kind of slowed the process, but it's up and running now. Just a few more tweaks to go. I'd love to get some pictures posted, but I'm still working on getting the digital camera purchase approved by the boss. I never expected that to be part of the reef "budget". Thanks again and I'll keep you posted.
