sump turnover rate

[RichE]

Up to you 24s suck in my opinion shafts snape off all the time.

So a 12 would be good in this set up? I have the option of installing a mag 7 along with the mag 12 if you think its needed.

I'm Asking you Dan, since your are the sump guy (thats what I was told:) )

I have 2 stacks draining into the sump and one return line going to the tank and I will be making a spray bar( I think)

Mag 24's have a tendency to blow the impellers apart this is why I think they suck. I know they did discontinue them due to this issue.

Now on to the turn over rate... There is really no good answer for this every tank is different. So lets say you aim for 3 to 4 times turn over in a hour. So a mag 12 is 1200 gph per hour at 0 head you will be between 3 and 5 feet of head so you will be at 1150 and 1120 gph i dunno what size the tank is 240 i assume. Even at 1120 you will be doing 4.7 times the turn over of the tank in a hour. A spray bar can lower the flow also so this is something to watch for and have a back up if it doesn't work. I prefer using locline but that is just me.
