Whoa! That's a biggie! Is it a reef or FOWLR? If it is a reef you should be keeping salinity at 1.025-6. Your idea to top off with saltwater is spot on, going up 14 ppt is huge, you should take at least a week to do this, but 10 days would be better.

Good idea mike. I'll keep my eye out for a hydrometer. Thanks for the info Myka. I'll raise the salinity slowly.

Ya, I use a hydrometer for day to day testing, and I calibrate with my refractometer once every 3 months or so. It does actually change over time.
