I think I have used just about every koi pond liner that Homedepot makes
At one point I was obsessed with LR and had ponds EVERYWHERE I was going to "corner the market" on LR, I had 2 of those 5' kiddie pools going that were the final pools, or rather rock that was fully cured, then I had 3x75 gallon tubs that were holding ponds for LR that I had no idea what I was going to do with, then I also had the huge 275g pond that was the middle step or for rock that was almost cured, then there was the hold and scrubbing tank so that I could clean the rock and then there were several tank around the house to simply hold LR that I had no other place to store. At one point I had about 2000lb of LR stored in every room of the house, there were ponds in the hallways, spare bedrooms, garage, bathrooms and I have a really nice home in a guard gated neighborhood, on the golf course! This was the point where I think I actully crossed over to the "Dark Rock Side"
...then it got very old, took a lot of work, just topping off all the tank was a daily chore and "Oh my god, the smell" I ended up taking all the ponds down and how have a single 55g for holding curing, sorry for my long rambling rant.

As for curing LR, the water quality should be the same for a reef tank, mybe elevate the calcium a little with "Purple Up" you can also take some LR that has good color coraline algae on it and then rub or scratch the algae off into the holding pond, this will seed the LR with coraline, run a good skimmer and do lots of water changes, thats why it's good to have so many pools as you can move LR around as it becomes more cured.......I have a friend who uses a 400w MH light on a LR curing system, he cures LR for people and encrusts it with corlaine algae, charges $1 per pound to almost totally encrust your LR.......
