u should have made the return pump chamber smaller now the main chamber for filtration is kinda small i mean i doubt that ur pump is THAT big and is gonna fill the whole chamber
@Devinhouchens
i would do refugium in center chamber after 2 filtersocks with chaeto and a strong light (AI primefuge would work since that chamber isnt too big.
then in the last chamber add a slightly undersized skimmer (itll still work since its the last filter the socks, and chaeto would prob have removed all of the stuff already; the chaeto is like a sponge) so ur skimmer already has less stuff to remove and if u think it wont fit I think it will:
this skimmer only has a 4"x5" footprint its tiny and rated up to 132G on RO's site
Lightly Stocked - 132 Gallons
Medium Stocked - 75 Gallons
Heavily Stocked - 40 Gallons
itll fit in the pump chamber with whatever pump u have i'm confident (unless ur running dual returns or ur pump is just an old massive oversized one :-/ )
the only downside i can think of doing this there will be no bubble trap after the skimmer (not too big of a deal tho the skimmer is a good quality one and not many bubbles will escape anyways)
i think its worth it tho that way u can have a proper sized fuge and a skimmer too
and imo in the 2 baffle spaces in the first one i would put 1 block of marinepure and in the 2nd a bubble trap sponge
EDIT: i said u have a smaller protein skimmer what brand and model is it? if u dont wanna buy a new one just go with big fuge in middle like i said and put that small tiny one u have rn in the pump chamber
