Well, time to update my thread. Since I last wrote the tank now has a pair of Vortechs up and running on opposite ends of the tank in anti-synch mode. Still not sure what the optimal settings are yet. Also, replaced the Barr Aqautic Skimmer. It was too noisy and I wanted to try some else! First I bought a AquaEuroUsa 250, which was noisy and not all that impressive. Then I decided that since my new DAS EX-1 was working so well on the 135 gal tank that a Aquabee mod was a good idea. I then acquired the stuff to mod the AE-USA 250 and proceeded to cut, drill, bore, and modify the thing and attach a pair of Aquabee pumps. The result has been fantastic! This thing skims beautifully. It took a while to fine tune the standpipe output, but it now produces fantastic fluffy clouds of gunk, that fill the skimmer cup with dark brown gravy skimmate. Got to love it. Also I have begun restocking after the devastating Marine Velvet outbreak earlier this year. I have added an Atlantic Blue Tang, a six pack of Dispar Anthias and a Blue Jaw Trigger. All are doing well.
