Has anyone ued these yet? I’m buying the Red Sea s1000. I can’t tell if the sumps has been improved to remove the sock tray and ad the reef mat? Also I was wondering about how long the rolls last? I know there will be some variance between peoples tanks. I just would like to here your size tank and how long a roll last? Am I going to be buying a $30 roll twice a month or once every two months. It could be a deal breaker. Any good or bad would be appreciated
