A few 20% water changes might help clean up the water a bit.
Disturbing the sandbed will reduce its filtration capacity, but I'm not sure that's a very important issue in a new tank with a reasonable amount of live rock.
I don't think a change in salinity is going to kill the bacteria...alot of live rock
survives being shipped wrapped in wet newspaper alone I'd assume there has to be some sort of swings in salinity due to that during shipping...
ahh. . well i already did it quick from 1.016 to a sudden 1.022? thats prob a huge jump right? or will they b ok? i prob should of raised it like 2 everyday! uhh o well ill just watch my levels and wait a lil longer till i add my nano
its an api test kit! it dnt change for no reason i dnt test it when i got the water the guy said it was fine saltwater that was ro/di water!! but it was only sg of 1.016You'll need to read the test kit instructions to try to decipher how to read the tube of liquid. Are these API kits?
Some water changes might help, and they won't hurt at all. Personally, I'd do 3-4 20% changes, but I'm on the cautious side.
As far as SG, the best way to handle the situation is to let evaporation do the work. Just top off with saltwater. I'd also check the accuracy of the measurement. SG shouldn't be changing for no reason. I'd mix the new saltwater to 1.026 and wait for the SG to match it before using RO/DI for topoff.
