1-1.5 lbs of LR
is just fine for a reef tank. I have around 1lb per gallon and all is fine and I have lots of fish and plan on adding more. I do have a fuge which is a big help for nitrate reduction. Im glad I got a 125 and if I did it over and knew what I know now i would have gotten a 180.
the 155 bow is a nice tak but Im not a big fan of the bow front, they cost more and if you look at the tank at the right angle there is a distortion. JMO.
dont take me wrong on the LR
, more is better but there comes a point when there is too much, I want a fish tank not a rock tank. again JMO.
