Sump advice

[Krazy_Karl]

In the process of upgrading tank setups to a 100g Cadlights Rimless. I have the stand built and it gives me 47.5" length of space inside. I have a 40B that Im planning on using as my sump. My question is: which way would you set it up?

Option A: 40B used as sump/refugium in the the following manner -

Skimmer > Baffles > Return Compartment (Eheim 1260) < Baffle < Fuge

Option B: 40B used as sump with a separate 10G elevated slightly next to it as a dedicated fuge -

Skimmer > Baffles > Return, then a 10G sitting next to it on the right which would be fed by the return and gravity feeds back into the return chamber

Option A would give me roughly 11" of extra stand space while option B would fit perfectly with about 1" to spare. I plan on housing my ATO container and electrical equipment in a separate area (possibly through a wall into a closet or a separate built stand). The only thing other than the sump(s) in the stand would be a BRS reactor which would be mounted above the sump on one of the walls (stand has 27" height inside). My only concern is that Id like to eventually purchase a doser which Im not sure would be able to be stored in either the closet or separate stand due to pumping distance.

Thanks in advance.

i would go skimmer, returns and baffles, then fuge , then waterfall with float valve+drive pump. jmo and good luck ,100gal rimless will be sweet:)

on my 90, i went with a 30g sump, skimmer,baffle,refuge,bubble trap, return chamber off to the side i have a 30g container for my ATO. i don't like the idea of the refuge being last in line. JMO

Which doser? Peristalic pumps usually pump pretty far. My lm3 will pump 25' high. I would set up the sump like option a with the 10 gallon in option b and make it a macro display or something species only pipefish etc. Or a frag tank with lower flow or something. Why not get one more tank out of all this work. You can even leave it un uninhabited and valve it off when you wanna do a quick 10 gallon water change without shutting down the return pump.
