I replaced my aquarium with a new one due to scratches on the old one. After tearing down and setting up the new one I noticed a line of bubbles in the seam. I took photos and got in touch with Marineland. After providing the photos,receipt and a photo of the build sticker they immediately authorized replacement with my LFS. The only PITA was having to go through the tear down again. I agree their quality seems to have gone down. I have been in the hobby 30+ years and have never seen such sloppy and lack of quality control work.
