need help with flow idea

[jokersplayground]

ok so im making a stock frag tank. the tank will be a stock tank from the lawn and garden store. it will be a 50g. my plan was to buy a mag 12 and plumbing pvc to it. the pump will be at the bottom of the stock tank. i will have diferent ventery points for flow. i was woundering if it will work as i dont want to have 10 diferent pumps in the tank.

I don't see an issue with this but I would use a pump rated for volume rather than pressure. The idea that you're toying with is that of a closed loop. Do some searching on recommended pumps for closed loop set ups.
