It still has some work to go, because I made an oopsie..
My problem right now -- I neglected to factor in the thickness of the top rocks, I also forgot to factor in the height added by the 5 layers of PVC connectors... This gives me a total height of about 18" right now, my water line is 17", I had planned for 13".
So my solution is three fold;
- Put a thinner rock on the top, lowering top rock from 3" to around 1" (+2")
- Cut a 1" chunk out of the top legs, lowering structure 1" (+1")
- Cut a 2" chunk out of the bottom legs, lowering structure (+2")
Doing this will give me around 5" more clearance, which should net me around 4" under the water. This isn't perfect.
I wanted it to definitely take up a lot of room, but I wonder if that top shelf will even be usable at 4" water clearance. That was my original goal at first, but seeing it in person makes a difference. I may need to take an additional step or two.. Otherwise, maybe I'll put a big table up there in the top back corner and let it cover that whole top rock by itself.
Anybody have any additional suggestions for lowering the structure height?
