I have a 2080 and I have a question. I have a 75g and I put the 2 intakes on both corners of the aquarium and the spray bar in the middle. When the filter is on high it moves my sand in the front of the aquarium down to the glass. How do I stop this? Is there a better way to setup this filter? Do I need to split the outtake to 2 as well or is that overkill? Any help greatly appreciated
