Hello all. I'm finally going to set up a used 75 gallon aquarium tank I bought used a couple of months ago. I am currently running a second water-test by filling it with hose water and allowing it to sit a couple of hours to ensure it wont leak when I set it up inside.
I am noticing a small leak under the tank in the left corner. The previous owner made a sort of chamber to hook hoses to in that corner (not sure what the specific purpose of the chamber is), and it appears that the leak is occurring from this alone due to some small cracks.
I'm wondering what the best approach is to fixing small leaks like this on the bottom of acrylic tanks. Not sure about types of sealant I can use; I went to my LFS
this morning and they do not carry acrylic sealants and were unsure about what to do as far as acrylic aquarium leaks go. Does sealing differ when a leak is occuring on the bottom vs. the corners and walls of the tank?
