I'll be heading to the zoo today (Saturday) at about noon to do some basic maintenance, if anyone is interested. So Ben and STN, if you guys want to come by, that would be great. I haven't heard back from Geo yet so we won't drill the seahorse tank today. I did order new lighting, and 1" bulkheads and got a plumbing list from Nate who has masterminded the design to integrate the seahorse tank into the whole system.
