My flow in tank is a tunze nanostream (modded so probably doing 5-6000 ltrs per hour) + my sump return which is 1200ltrs per hour. I have a 175ltr tank + sump/refugium. Do I need to do anything different at night with my flow or just leave it running? Also, what is the deal with these LED moonlight simulators? Gimmick, beneficial to reef only or beneficial to reef and fish?
Thanks!
Thanks!
