Hi guys! I'm upgrading to a 3 feet setup. I've never had anything besides a 2 feet 5 plan tank before. Need some advice on the new project Tank dimensions 1. What are the standard (i.e. no need to custom make) tank dimensions of a 3 feet tank? 2. Are standard sizes cheaper than custom made tanks? 3. What would be the height of the tank you'd recommend if I intend to keep some softies/lps at the bottom (4xt5HO likely)? Sump setup I'm more inclined to go for a sump instead
