Commissioned a well know tank builder in the mid-atlantic two years ago to build me a tank 96x36x24. He tried to screw me over and built one out of one inch extruded. I of course immediately knew the difference, threatened to sue him, he blamed the mix up on the shop where he gets the acrylic (yeah right). I paid for a well built tank with clear seams, and he delivered finally, or so I thought. I got wrapped up in a nightmare of a job at work, the tank sat outside (on its back properly stored for 6 months). Finally got it on the stand, the stand is wood, planar, level, and has half inch dense foam and now I am seeing air bubbles developing in the bottom seams before I have even added water (it has been another six months since tank was put on stand). All vertical seams are perfect, top is fine but bottom has two spots that are concerning. Aside from suing the builder which is likely to happen, I am looking for options here. I dont want to install one inch triangle rod if I dont have to, but the fact that air bubbles are developing without stress is concerning. Did he use super glue instead of weldon? Has anyone seen a tank do this without water in it? Any help here is truly appreciated!!
