Sump design

[J_Escobar]

Hi everyone, I'm in the process of setting up a new 55 gallon reef tank, and i want to build a 30 gallon sump for it.
I have been reading a lot of information over the las couple of weeks and i came up with this design.
I will appreciate any comments or suggestions.

Ps. I have a hang-on Remora skimmer all ready

Thanks, J Escobar.

Looks good, minus the bio balls. If not cleaned regularly, they become nitrate traps. I'd remove those, otherwise it looks good to me
