Jason-
Don't get me wrong, but I think you should pull the trigger on a much bigger, longer tank. You seem to have the money to spend on all sorts of gadgets, why not use some on a bigger house for that pretty fish? Also, a bigger tank means a bigger stand, so you can put all the equipment out of reach of your toddler. Seems like a win-win-win to me.
Just my two cents.
BTW: Why not just run the RODI feed/waste tubing under the house where it will not be treaded on? I am thinking that someday your going to see a leak in that room. Drill two 3/4" holes in the floor and your done.
Sorry - don't mean to be overly critical. You have some nice equipment. Hope the tank inhabitants benefit.
