Here's the scoop. Seems that Hoot did not test the blocks using his Eheim 1048. What he did is set up his spiget to deliver 158 GPH and this is why he had higher flow through the blocks. What was forgotten was the pressure between his home and the pressure that the 1048 can deliver. Hoot is going to retest the blocks using his pump. Plus with Hoots setup he does not have the lift I have.
