For water changes, how does the salinity in my tank relate to what the sg of my RO water should be when I add it?
ya thats super high so you're gonna want to put some non salt water in to get it down to about 1.025 but if you do it right away things may go into shock. do you have fish i can't see any. I'd syphin out a little water and add some plain water without out salt. maybe half a gallon to start. let things sit for a day then do it again. if you drop the salinity to fast you could be in trouble but over the next few days you should be ok. If you don't have fish you could do it faster but your coral may close up for a while while it adjusts.

when you're doing regular water changes your salinity should match what your tank is.

Bioballs or LRR?

The lesser of two evils is still an evil.
