email@example.com Posted September 30, 2021 Share Posted September 30, 2021 A year-a-go my very sweet husband bought and build a beautiful racking system for my new fish room. Unfortunately the boards that came with the selves where OSB. I was unsure about the OSB but I lost that battle. In the attached picture the bowing is very obvious but life happen and we put off fixing one day to long and, yesterday the tanks came crashing down lost three colonies of breading fish and shrimp. The rack themselves seem to be fine. I want to use 2X4's to use as decking and my husband was to use composite decking because if the water resistance. Looking for guidance. 3 Link to comment Share on other sites More sharing options...
