maintenance will likely be more. You have to consider salt, RO
topoffs, sand, lr
, which will cost considerably more being this size. I will soon feel your pain though. I am looking at getting either a 240, or a 300 after my house is done.
Add these expenses up on a piece of paper and see if it would be worth it. The initial investment will be costly if you want to do it right, and the maintenance will be a little more costlier than a smaller tank. I suppose it could really depend on what tank you are going from?
