looks like it'll be awesome. May want to consider how much pressure your retention frame is putting on the acrylic...you'll want a significant amount since the silicone won't actually bond to it from what I understand (haven't tried it myself, just saw it on another thread). If you aren't going to get into it anyways once it's in place, you may want to just do the decor before the big lift and then mount on the inside in order to simplify. You risk having a few things get out of place and have a heavier lift, but you could probably make some custom tools that'll let you move stuff around inside the tank once it's in place. Good luck with it all and sorry to hear about the ankle...I feel for you on that one!
