or one big pump spilt into 4 returns would work as well !!
but after diving in cozumel and the current was pulling us soooo fast we shot past the pick up boat by over 1/2 mile i know that high flow is important for many reason !! even setting a rio 2500 right into a tank watching all fish, they love swimming right into the jet stream with very very little effort ! which ive always wondered how much flow it would take for lets say a trigger to not be able to keep up ??? and my point basically is that i feel most people have mabe 1/4 the water flow they could or should have in their tanks !! my 90 i use a mag 24 inline with a little giant as my main return and a mag 9.5 as another return and three maxi-jets 1200 in the main tank as well !! but feel i could still us more flow !! do i need more flow prob not but i like the movement and so do the fishs !!
