I checked out the zoo tank today (Sat. 8/25). It looked terrific. The diatoms were completely gone. Nate said in joking that its because we got rid of those ugly white actinics. I wonder if that could be a factor. I have also been trying to maintain the alkalinity at slightly elevated levels in relation to the calcium which my reading indicates can really help. iI filled the alk and Ca dosing buckets and tested all parameters. I still had to boost alk and CA a bit but everything was great. The yellow tang started feeding as well. There are also some signs of corraline algae starting to get a foothold. I also tried banding some nori to a rock and the Naso came right over and literally ripped it out of my hand. He is the coolest fish ever. St. james had no major reason to give that fish up other than his desire to contribute to the cause. Now that the tank is astable, I will start adding more sps and other coral. the girls at the zoo especially jenna are doing a fabulous job of following the tank care protocols. Finally, I will be placing a LiveAquaria order tomorrow if anyone other than nate wants to jump in. Oh, I almost forgot, DaveVG did a terrific job on the pulley system. We still need a better latch configuration.
