Hey all, was wondering if some one can help me out or may be know some one who help me out with my problem... I was in the process of setting up my 150 gal acrylic tank and ran into a pretty serious SNAFU. I put the sand in the tank and filled it with about 100 gal of already made salt water and then one of the internal overflow seams popped off the back of my tank and the water went into the overflow thru the crack. Anyone has any experience with this or know how to remedy the situation? I drained almost all the water and will take out sand tomorrow night. I think the tank needs to be completely empty for the repair? Appreciate any input! Thanks!
