Hey guys, newbie here. This is my first post and looking forward to be a member on this great forum. After about 10 months of owning my first reef tank (425XL), I upgraded yesterday to a 525XL. I was about to redo the rockscape on my 425XL when I found a great deal on a used 525XL. Very happy with the tank and think its the perfect size. I could have jumped to a 750 that I also found a great deal on but I think the 525XL will suite me will. I will be posting my 425XL for sale soon once I do the transfer. Will also be looking to buy things here for my new tank. Happy Reefing!
