More update...
Finished the plumbing today...
Leak test...
Looking good is far...
Leak test was a success! Turned off the return pump to simulate a power failure. Whew, just enough room...
Jon was over to help me move the tank in place and we drained the water and added RO water and salt...
We also tried the lights over the tank...

Able to swivel the lights out of the way to add the new RO water into the tank...

Could not decide in whether to have the lights positioned horizontally or perpendicular to the tank...

Another pic of the sump...
