Im still trying to decide what way to go lol. I really liked the redsea 250 I had. It seemed like a pretty average size. And from what I'm seeing the prices are crazy high. Even on FB market for a used setup. That's my second decision I have bought in the past established tanks locally. It seems even there close to double as they use to be.

Both the Fluval Flex and the Evo are amazing aio starter tanks. I began with the Fluval Evo 13.5, and it was a great way to get into the hobby. For someone with more experience such as yourself, it is a great way to get back into the swing of things and understand contemporary reefing practices.
