Algae Turf Scrubber. To turn off or not to turn off. (1 Viewer)

[Scott Zurek]

I am wondering if I should turn my light off at night, to leave it on 24/7 or run it opposite of my main lights.

I run opposite to help with Ph drop at night.

Yes. From my studies opposite seems to be the preferred way to do it.

There are arguments on both sides, but I find it beneficial to have a dark period for at least a few hours each day.
My scrubber's photoperiod is currently on for only ten hours each night and it's keeping my nutrient levels very stable. I'm harvesting every ten days or so and I'm still getting ten to fifteen ounces of algae per harvest.

I've got mine running 22 hours a day. It's completely full in about 5 days.

I’ve been using a horizontal ATS for over 12 years. 18 hours on 6 hours off. 10% water change every 2 weeks. 90 liters aquarium. The skimmer was put in without my consent. Serves no purpose as I only leave it running not skimming anything. Auto replenish magnesium, potassium. Got a new auto detect Kh and doser.
