if the salinity measures a little low but the tank is full

[sahara910]

do you just add a tiny bit of salt to the tank itself?

 

[mockery]

mix up some water that higher salt or you could top off with a little salt water

I would take a gallon of water out of the tank and mix salt in until completely dissloved....then add that back into the tank....do this over a period of time (over a couple weeks) until salinity is right. Adding salt to the tank itself with livestock in it (assuming you have livestock) will be a bad idea.

sorry I am just cycling for a new tank I have live rock/ l sand in there

If you have a sump, dump it in there. Otherwise, take some water out and add salt. Once disolved, add it to the tank.
