Whoa! 230lbs of rock in a 140G
One thing I would say is be very careful it doesn't just collect detritus. You can have too much LR in a tank if it cuts off flow and creates dead spots or areas that just collect crap (literally).
Sump is good but again be careful. When I keep rock in the sump, I use PVC to raise it up off the bottom a bit so water can flow through the sump freely. Otherwise I used to find that it just collects detritus.
Why not just keep like 140-180 lbs. and make some money for frags off the rest?
