Have one of those myself. Does a pretty good job! Been running straight for 1.5 years, no problems!
as you know al..i use alita pumps anywhere from the 40 to the 100..the 100 is crazy powerful and will run a heck of a lot of tanks..in my experinces, the 40 will run a biochamber sump for a 750g with alittle to spare for tank air discs..a 60lpm will give you alittle extra boost and that's model has been my staple for years.
