Not sure if this is the correct forum for this question, but here goes: I have a 46 gallon bow front fish tank and last week I added a container of aquarium salt, with holes in the top (appropriate to tank size) to help combat some flashing that was happening with my fish. A few days after adding the salt, I noticed what looked to me, like salt creep happening on the front of the tank, right in the middle of the bow on the bottom of the tank. It appeared between the glass and the bottom brace. I have since scraped it away but in the back of my mind I am worried about a slow leak. Where this had occurred, there doesn't seem to be any moisture per se, that is to say if I put a tissue on it, it doesn't come up wet. I also have a glass lid on the tank and the bubbler is far enough away from the front of the tank that it should not cause any moisture to come off the top and down the front of the glass. I haven't seen it come back...yet, but if it does, should I prepare for the worst?
If anyone has experienced this phenomena before and can give me some advice that would be great! Thanks!
