Not sure now.
Do I paint the entire 30 gallon breeder black (put a lid on it and turn it into a remote DSB or have it as a refugium?
Both with feed back into the sump via gravity.
Was going to use the 30 gallon breeder as a Remote DSB and use a sump that is designed built for a refugium as my refugium.
30 gallon is roughly 36" (L) X 18" (W) x 12" (T) no baffels just plumbed
Sump for refugium is 17" (L) x 12" (W) x 15" (T) has baffels and is plumbed
Just not sure if its more benefical to have a bigger refugium or a bigger remote sand bed. or are they close enough in size that it doesnt matter
