68 Gallon Rimless Reef Build

[zhasan]

I'm also a little perplexed about my sump design.

I'm thinking of a 3 chamber sump. First for Drain and Skimmer, second for return and third for fuge.

However, I only have 36" to play with.

First section will be 16" next for return will be 8" and that leaves me with 12 inches for fuge. Is that ample size for fuge and return chamber?

Here is a pic of the "to be" sump!
