Suggestions for salt creep?

[Rcyphermd]

My 600 gallon tank has a lot of salt creep. I have minimized bubbles hitting the surface. I tried to attach picture, but the link doesn't work. Any suggestions? I hope the tank doesn't have a small leak!

The tank also contributes humidity that has salt in it, so salt creep just happens.
IF it appears around piping joints then you need to check it out.
