I bought this tank off craigs list. traveled 4.5 hours to get it and brought it home excited the whole way. I've got about 475-500 in it now counting gas and what not. Last night when we were unloading it i noticed all these micro-fractures in it. I thought i had done my research about polishing acrylic tanks and what to look for since this is the first ive ever owned. I guess i was wrong, i didn't even know "crazing" was a thing until this morning. I have some pictures, i need some experts to please tell me if this thing is worth polishing out or if i should just use it for firewood. (I heard they are very flammable this morning as well haha.)
I can deal with the crazing being there you can barely see it with the tank filled. I set it up on a nice level pad last night and filled it no leaks or bowing. Its 73x30x18 with 1/2 inch acrylic panels. it has an overflow in one end but has never been drilled. I believe it may have been in a dr office and might have been cleaned with windex or something but i tried a section and it got crystaly clear with just novus 3 and 2 so it will definitely clean up.
Just tell me if this things going to explode or not.
55 gallon for scale
and these are the edges with the crazing. All edges look crystal clear except the bad spot pictured.
and the bad one, right front center bottom.
it holds water fine with no bowing that i noticed. ive read this is very common and i can say i will never buy another used acrylic tank i will stick with what i know and thats glass. im sick at my stomach now because i thought i finally was going to have a big tank and now i think its just trash.
