Salt creep visible under tank

[Kati537]

Hey guys,
I am seeing some salt creep underneath my aquarium when I poke my head under the stand. It is visible in all four corners (see pictures). I’m wondering if this is caused by a slow leak or if this is normal. I’m moving the tank so it could be a good time to replace it if needed. It’s 75 gallons with a 29 gallon sump underneath. The protein skimmer does seem to spit out a few water droplets, but I would think the salt creep would be in the middle of the tank if it was from the sump? I needed to top off about 2-3 gallons of water once a week in the summer, and now that is up to twice a week but i’m thinking it may be from dry winter air. What do you guys think?

Could be from water running down the glass and into the frame at the bottom from doing maintenance, sticking hands in tank and out, fish splashing, etc.

Tough to say for sure. One of my systems has salt creep everywhere because every time I walk by the tank the foxface (very deliberately) splashes me. The other system has none to very little.

I'd suggest scraping it clean and wiping down dry, and then checking every day or so for new moisture or creep just so you have a sense of how much is escaping, and where it first appears.

To me, it sounds like an excuse to upgrade but then I am always imagining new excuses for that.
