Salt build up on the side of tank

hello everyone so i've had my tank set up for alittle less than a year and just recently i noticed there's been salt build on the top and side of the tank. Now i wipe it down but a few days later it's there again. What do you guys suggest?


it's not a big deal so as long as the tank is not leaking. it's probably a humidity thing. keep a close eye on your gravity and salinity. and make sure your topping off when needed.
