Sump questions??

[blenny boy]

I am up grading my system to have a 30 g sump with my 30 g tank... guy at the fish store sold me a mag drive 7 pump and suggested I submerge it directly into my sump tank...
3 questions
1. will submerging the pump greatly impact the tank temp?
2. is 700 gph pump too much for my system?
3. could I simply use a strong powerhead (like the aquaclear 802) as my return pump - this would certainly add less temp to the tank

• With a MAG pump it should not.
• The MAG is not a very strong pump, depending on head pressure
  No, PH don't have enough head pressure to get the return back up to the tank.

thanks for the information...
checking in archieved threads there seems to be some debate re the heat that comes off of mag pumps... any more thoughts?
