sump help plz

going to change over to a sump filtration tank. we think we are going to go maximum size we can fit in the cuboard under the d/tank, that will be around 4foot long and 20 inches from back to front, 18 inches deep,

display tank is 800 ltrs before displation

this is going to become a reef tank we dont know the size of the skimmer foot yet but will do soon, return pump not sure yet
OR6500 maybe?

do we have one made with 4 sections or 3 ? anyone got a tank this size that uses a sump can you show a picture plz and maybe some info of how yours is ran plz.

mud or d/s/b?

was thinking in sections 1, skimmer and filter sock

section 2, two ReefresH2O blocks as ive already got them

section 3 dsb or mm? What is best for nitrate? Would like to light the sump and have cheato in it, can you do this with dsb ?

section 4 Phosphate reacter, nitrate reacter as ive got one, return pump

any input would be great

 

i made a 20 long glass into a fuge...i have 3 sections, the first section is where my skimmer/sock/carbon is...the 2nd chamber is my fuge with 20ibs of sand 10 ibs of live rock, cheato/culurpa with a "marco algae" light (13w), and heater. The last chamber is my return pump. Since u have a pretty big sump u can make 4 chambers and add more goodies, Just remember whatch out for heat spikes...since u mite have more pump/motors etc... GL
