ok,I didn;t want to confuse myself but sence you had to go there!
I will play both sides of the coin.. if you change the intake so it is very small (ie. get rid of the suction strainer and put a extended pipe on it. it will
help to creat a current in the tank. the problem is because of the chareristics of water flow it will not be as defined as the output. so you might be creating a 1200gph suction but as far a a current effect you might only notice the equivalance of say 200gph. see whare I am going?
yes you are sucking 1200 gal and throwing out 1200 gal but the main effect you will notice from the suction is a "psudo direction" of the output. ie. setting up a whirlpool in the tank
