They said they bought the sump last year new for $200. I am brand new to sumps...but also thought it looked a little small too.
Seller said that the tank holds water and has never leaked. But they said that they are pricing it so low because it isn't a pretty tank. Said they added some extra acrylic to the inside corner seams for extra security. To my understanding shouldn't all seams be removed before adding new ones? I've never had acrylic tank before though.
Also said there are water stains on the inside which aren't visible from the outside.
I missed this comment and just recommended this to you above. If the appearance doesn't bother you I saw go for it. Just make sure it holds water (in front of you) prior to purchase.
It is also incredibly important to have the tank well supported underneath and level. Any seam issue means you need to take extra precautions to not further along more issues
