Thank you for your reply. The reason I'm going with the 200 is this is my one shot and last thing I wanted was the urge to go bigger.Welcome aboard! Like every else here I agree you’re never too old. I also agree that the 200 may be too much to handle, but that will ultimately be your call based on what you think you can handle.
I started my first reef tank last September (I had fresh water throughout college, my first, and into my current marriage) after six months of research. I ended up with a Red Sea (G2) Peninsula because it was the only tank I could find that fit the space I had. The display is 74 gallons, and the tank is a non-standard 3’x2’2’. I love the extra height and width over the 18” models. In our world, this is considered a small tank, and I struggled with it initially because bigger is better. I almost went with an IM custom 100, but the added foot of width brought it too far into the room. No, the 74 was it like it or not.
Turns out that, while I think I could handle a larger tank, I don’t want to. This one is a perfect size that doesn’t demand all of my time, so my time with it is more enjoyable. There’s something to be said for that balance. Good luck and enjoy!
Something to consider.
