Update! I’ve done nothing since my last post. Well kind of. I decided to eliminate the internal overflow and switch to a modular marine overflow. They warned me about a wait on the website but I had no idea it was going to take 5 weeks. In either case I postponed breaking down the tank and I’m planning on doing it sometime in August or early September. I will break down the tank, eliminate the internal overflow, drill the tank for the external, and set up the tank on the new stand with new plumbing and partial new aqua scape…. Seems a little overwhelming. I may have to take a whole long weekend to get this done but I think it will be worth it in the end
