Hey everyone! Been a long time since my first reef tank (55 gal), and decided to dive back in. Ended up buying a used 100 gal low iron glass tank with stand and trigger sapphire 34 sump. Tank had not been running, just sitting with water (guy I bought it from was going to set up but got more interested in terrariums and frogs??). Anyways, got it home, and being my naive self figured out this was probably a diy tank. Filled it up with water and some vinegar to clean it up. Let it sit for a few days, no leaks. Had some pvc hard plumbing, but I will probably redo all that. No equipment yet. Anyways, besides the first day of buyers remorse (what did I do? Why did I buy a used tank! And it appears diy!!) I have calmed down a bit. Tank seems solid. Let me know what everyone thinks
