What was your first aquarium?

nice
do i need a sump for a 40 breeder?

There are a few nice advantages to having a sump. It will give you a larger water volume which will aid in helping to keep levels more stable easier. It will give you somewhere to place your needed equipment ie; skimmer, etc. Some even use part of a sump area as a frag section. When you go sump, you won't want to be without one. ;)

My first reef was a TMC signature 900. Gave me a good few years before leaking…..
