suggestions with returns into DT

[salt210]

ok. I have been wandering if it would be better for me to aim all 4 of my returns to the surface rather than for flow inside. I have 3 PH's in the tank for flow. I have read that this will help with oxygenating the water and with cooloing the tank as well.

I went ahead and now have all 4 at the surface

move them back and forth until you get the right spot for them. personally, i don't have any powerheads/returns aimed towards the surface, but the dispersed flow of one of the koralias hits it somewhat.
if you have a protein skimmer and an open top tank, you don't have to worry about oxygenation too much. the protein skimmer puts alot of oxygen in the water.

protein skimmer is in the sump and glass tops

it doesn't matter where you have the protein skimmer. it's still putting oxygen into the water.

ok. had to clarify. I've noticed that moving them created dead spots, so ill be putting them back
