I also forgot to mention that I saw a VorTech today in action, and really liked it. I also saw the battery back up, and its nice and compact. I think I want a pair, or maybe three, however I need to think through where I would place them, and how I could use them optimally within our system. I want to try and wait for MACNA to purchase them, however, I know myself, I have little self control, so no promises.
I am also going to pull out some rock soon, maybe tomorrow and see about building a pillar in the tank, and arranging the small islands for my new SPS. I want to hold the pillar together with a combination of epoxy, and maybe thorite. I want to avoid having to drill the pieces, or add in PVC or acrylic rods. Anyone see any problems with using either of these? I would probably cure them again after before returning them to the tank.
