OK finally got my 125 w/40 sump cycling. i'm trying to do everything the right way. i have ro water s/g @ .0121. dual overflow plumbed down into the sump. about 50 lbs of live sand and about 100 lbs of live rock. asm g3 skimmer w/sedra 5000. and quite one 5000 return pump for now. in the process of sting up refugium- what exactly do i need for that? i was told i can use soil??? some live rock and cheato?? the only other thing i plan on adding as far as equipment is a uv sterilizer. then when i plan on adding fish i'm going to make a list of what i want, but how do i know what can coexist with what. and what goes in first, then second, etc....
