How's my filter setup?

[lololobster21]

It's a fluval Evo 13.5 a box of marine pure gems, and some carbon in the first, A sea lettuce refugium in the center with more media bio media below (algae barn kit) and a sicce 0.5 in the last. Im gonna get a small refugium light for the center in the future unless it's not necessary.

It's my first saltwater aquarium and would like some tips or ways to improve. I only have some inverts rn and plan to do a small reef nothing insane.

Thanks!

Looks good. I'd probably remove the blue/white filter floss in the left chamber, but other than that I can't see anything else.
