This tank started to leak so I replaced it. It was a very slow leak from the back lower trim. I believe the cause was the tank being placed on an uneven stand that allowed the tank to lean back towards the wall. I bought the tank new in dec 2014. It still has the sand in it. I'm going to toss it on Monday if no one wants it. I'm in Lafayette. It is pictured in the link below.
