Instant Ocean works great for me, 1 cup per 5 gal., don't even need to test salinity, always perfect.

Weird. I use 2.5 cups for every 5 gallons.
I just saw your post. I use Red Sea Coral Pro too. I had the same problem last year when my LFS ran out, so I bought a small Reef crystals to use for a few weeks. I had no issues. Using a different salt for one or two partial water changes will have minimal effect. Just watch salinity with the new mix. Dose cal and alk as needed.
Opps just saw the date, your already done.
I vote reef crystals too. Great salt and won't break the bank

I use reef crystal. it looks like the price is going up up at Dr. FS do to them starting their own salt.
Anyone use Live Aquaria salt?
i Dose to keep my levels constant
if you have an sps dominant tank or too many sps .. alk usage would be more ..
this monster named alk is a different kind than other parameters like Calcium/ magnesium and other trace elements ..
different being - for other elements corals just neeed to have them and as long as they have more than they desire they are good to go .. where as ALK ... corals need to have a stable value for this and any major change in its level either way would hurt corals ..sps more than other types of corals.
so lets say its 9dkh after your water change and over a course of week it dropped to 6 dkh and you do a water change and bring it back to 9 .. thats 3dkh to some sps is like drinking a sip of chilled beer between sips of your hot morning cofee if it makes sense
i use aquaforest for my sps tank - mixes at 8 alk and i keep alk at that level with dosing .. i still do weekly water changes but to replenish trace elements not the major elements.
and use red sea coral pro with my lps/chalice tank - because it has more magnesium than aquaforest which is what chalices and lps like .. but mixes at an alk of 11 dkh which is a bit too high for sps.
yep thats right .. nothing is easy in this hobby haha
