what is your reef tank salinity?

I use a drip method for my top off - holding tank is above the sump and drip it in at a steady rate with airline tubing. It takes a few days to figure out what rate to have it at, and there is some variation depending on how hot the day is. It is not as good as an ATO, but it works for me and no danger of malfunctioning float valves and pouring fresh water into the tank causing a sudden drop in salinity, I have read a few threads about that happening.
