sump light

[paul]

just curious aboutmy sump. do i leave the light on 24-7 for cheaato to grow and absorb nitrates. or do i alternate lights on opposite schedule of display lights. thanks.

Most run an opposite cycle, myself included.

Running a fuge with lights opposite your DT also helps to maintain your PH level, which tends to drop when the lights in the DT turn off.

We run ours 24x7. I think either way is fine.

I used to run mine all the time, but that changed when I started to put frags down there.

depends what kind of macro you are using
for the caulerpas, the 24/7 schedule is better, because it prevents it from going sexual, chaeto doesn't go sexual, so reverse light cycle is fine to combat ph swings.
