Sump design question

[JoeA]

Hi Guys,

I want to start a FOWLR saltwater tank. The display tank is 55gal long and I just purchased a 20 gallon long glass tank to make into my sump.

My guestion is how would you design the space inside the sump. How many baffles and such. How is your sump designed and why?

Any advice is GREATLY appreciated.

I would provide at least 3 baffles to keep micro bubbles out of the pump inlet. A 20L is a large sump for a 55. Will it fit in your stand?.
With a glass sump it won't be drilled for an external pump. Be prepared for the heat generated by a large return pump.
Incorporate a level float switch for an auto top off system. HUGE convenience.
