Hello everyone!
Background
I have been following various threads/people on R2R. It has been really helpful as I want to restart my old Waterbox 15 tank.
I had to move to a 5g tank due to time and rental apartment constraints. I have a pair of clownfish(4 year and 2 year old) with just some live rock in it. I did keep some corals but could not maintain it so I had to remove them at that time.
Tank Setup(Updated: 09/24/2025)
I hope to start the tank once I receive the rock from TBS by September 30 and will keep updating the thread with all the tank setup. Thanks!
