Husker, great system. I agree, as awesome as your 240 is, this Lagoon is just amazing. It had my attention enough to read non-stop every post in all 6 pages. I agree with you that a viewing panel would have been nice, but hindsight is 20/20 and yeah the thought of 1000 gallons on your floor would make me slightly hesitant, lol. But am I the only one who thinks you need to go rent an underwater camera and do some clicking away? I'm sure one of the local reefers will be happy to lend you theirs in the name of reefing studies :lol: Great work, can you give us some updates and pix on the system?
