Hello World

 

A tank with a sump maintains a constant water level in the display - the level goes down in the sump, makeing it the perfect place to have an auto top-off (ATO).  You can hide things like probes, thermostats, heaters etc there, instead of in the display.  You can also keep critters in a sump that can't live in the display due to the fish etc you keep there.  It's a "refuge" for these beneficial critters - hence the term "refugium."

 

I have a sump for my large FW tank, but not for my 90g SW  - if you have a choice to get a drilled or "reef ready" tank, I think it's by far the best way to go.

The light is mounted above instead of enclosed in the tank.  This makes it so that your tank doesnt get as hot.  The Nano's that they have at the Aquarium all have chillers because of the heat problem from enclosed lights.

I also like how it has a window in the refugium compartment.  It made it really easy to mount the jbj led lights in that area.  It is really helping my growth.

The 3 compartments in the back seem to work perfect for what you need.

It also comes with a protein skimmer.

You are welcome to come see mine anytime.  

I also bought this brand new online for only $380 shipped.
