Updating...
got the 150 filled with 5 inch DSB, a few pounds of live rock and overflowing to sump with return at about 600 gph... a couple small powerheads...the return is as a underwater spray bar to diffuse the current...i still plan on doing a closed loop system, but no rush
put some turtle/manatee and shoal grass in from floridapets in the 120...its a bit mucky in there but also put a load of snails in..
now i let the system simmer a bit as i save up for lights for the 150 and more live rock
