I like the CPR's.And the Turbofloater 1000.I am running a CPR SR9 on my 130.It is a monster,and wont even fit in the cabinet.I have it sitting on the floor next to the tank.It is rated at 300 gallons.Now after six months it is pulling very little foam per day.I believe that this slowdown is because it has eliminated my tank of excess protiens and other waste.I love this skimmer and would reccomend this line to anyone.
