Fans help no matter what lighting you have. One on the surface of the water and one pointed into the sump is what I use. I have Azoo fans, they are cheap and last a couple years. I find fans don't usually last very long with all the salt creep they attract so the economical Azoo fans work for me. They are quiet. Jebo makes a similar model.

Bought a used chiller that is questionable at best.... I'm trying 3 fans on a controller to see if that will work enough for me.... Otherwise ill need that chiller working/fixed. Ill let ya know I just setup my apex lite tonight!!!!
