HC, nobody said that you needed LR
or lighting. That is just the way most set their tanks up. LR
and a skimmer for filtration and it looks nice. Plus, many people love corals and the adventure of LR
If you wanted to start out with just a FO
tank you dont have to have LR
. You could set it up with some kind of filter, maybe canister, couple of powerheads, and a heater, or maybe wait until you do want to spend the money so you can have a really nice tank.
If there is one thing everybody has told me from the beginning it is that this hobby is expensive. If you don't want to invest money, maybe you will be happier staying with the F/W for now.
