I have the option of two tanks. One is 30G and one is 60G 30G for 35$ Length: 30" Height: 18.5" Width/depth: 12.5" 60G for Free Length: 36" Height: 30" Width/Depth: 13" I'm not sure if it's just me and my lack of experience but is 12.5-13" inches too narrow of a tank? My last option would be get both and use the 30G as a sump or refugium for the 60g. Which would you all suggest, I know many of you will say 60G because a higher volume is better for stability and all but I like small scale/easier to maintain a bit. I only intend on having a light bioload. What are you thoughts and things I might be missing because of my lack of experience? Also anyone have a good guide to initial tank cycling?
