From the aquacraft (of the infamous S-15™ Report™) website:
"Different oceans have slightly different specific gravities. The tropical Indo-Pacific has an average specific gravity of 1.022 - 1.025. The Caribbean has an average specific gravity of 1.023 - 1.026. The Red Sea has an average specific gravity of 1.028 - 1.035. The specific gravity changes in each area are due largely to rain fall."

Fish will generally do better at a slightly (1.018-1.020) SG while most corals prefer 1.022 - 1.026

As I mentioned above it is .49cents per gallon at one of my LFS. From the LFS you buy it in bulk and they just fill up your water jugs you bring in. Of course PetCo is going to mark up their 5-gallon cardboard box full of water.

Ry, I would make sure to add a ph to a bucket, to get the pH up to your tank's just to help relieve stress, depending on how much of a PWC you will be doing. Also, keep in mind, the FW will evaporate and not the salt so top off your tank with new FW otherwise your salinity will increase. When you do your PWCs, use the Catilina water.
Age is relative, you are only as old as you act....of course, this works in reverse....

Questions loved, heeded advice greatly appreciated!

Just be careful when adding livestock from a tank that is at 1.025. You might need to acclimate a bit longer.
*180 gal Display, 100 gal basement sump, 33 gal refugium, 3x250 MH, 2x160 VHO actinics, zoos, some softies, LPS & lots of acros and other SPS.
*100 gal prop tank plumbed into main system w/ 2x96 PC lights and 1x150 MH,

I agree with Ellisz...if you are adding things from a tank that has a much higher SG you will want to take extra time and care in acclimating them to your lower SG.

I keep my tank at 1.024 and things are looking good!
