I do have most of that in the DT, probably about 30 lbs in the sump from the 200. The tank is between my family room and office so dual viewing. I have a established 55 gallon as well that is shy of rock so likely some is destine for it. I welcome the advice hence the posts as I took over the 55 (abused tank and critters) in May so still very new to the hobby.

OK
You may want to buy at least a PO4 test kit, or better a Hanna PO4 digital meter. Or at the top of the scale is a Phosphorus Low Range Meter $$$$
The Hanna PO4 will do you just fine (the phosphosus tester is very low range and you don't need it). You can get it in Canada from Reef Supplies but you will need to make your decision about what tester you want - phosphate or phosphorus

Since you opened the door ...

Get all that extra rock out of your tank and dump it in a bucket, including the stuff you have in your sump. It's just a big detritus trap
No LR in your sump is a good idea. Some do it with success, but you have to keep it clean

Look over all your rock ...
Play with it in your tank. Make different piles. Get it the way you want it.
Take it from someone who has limited space in a 75G ... keep everything away from the glass for cleaning and, above most for anyone, keep the structures below the half-way point top-bottom so the corals have somewhere to grow.
I've looked at so many great-looking tanks lately that I'm convinced the best-looking setup has the LR stopping at half the height of the tank

After you have decided what you want to keep, Sell that stuff !!! $$$
