Is my tank leaking?? HELP!

[fishyfun2]

Ok, this may seem like a stupid question, maybe it is. I always thought a leak would be really obvious. I have been having salt creep and a slight amount of water building up all around the black plastic at the base of my tank. Some of it is on top of the plastic, like where it meets with the glass, but mostly on the bottom where it meets with the stand. I don't notice that I'm topping off more water than usual, so this must be pretty slow if it is a leak. My salinity is lower than I usually have it. Last night it was at 1.023, I'm usually running at 1.025.
Do you think it's leaking? What to do to find out for sure?

DO tou have any equipment as HOB that could be the cause?

Hi,
I have an overflow box with tubing leading down to my sump, and of course, the return tubinb. No buildup of salt either of those places.

I have similar creep on most of my tanks from time to time. I believe mine is mostly from the small amount of water that runs down the front of the tank during water changes, feedings and and fragging adventures along with the hob filters, skimmer, and cords/tubing. Just my opinion. Hope it helps

Thanks, that does help. On yours, do you notice the salt buildup coming back after it has been cleaned off? I guess that is what is concerning me.
