Algae Scrubber progress advice?

[anthonymckay]

My ClearWater scrubber has been up for 4 weeks as of today. Lights have been on 24/7 this phase and screen hasn't been cleaned off yet. I'm starting to now get turf algae growing, though not thick across the entire screen yet. Wondering if this progress seems on track? Should I scrape this off now and drop down to an 18hr light schedule?

Looks good. How are your nutrients?

Currently no3: ~25ppm, po4: 0.06

Bump, anyone with some insight?

I didn't see real growth until I put the light on a reverse cycle. Nothing grew when the light was on 24/7. So now its on when the main lights are off. Then BAM explosion of growth.

Thank you, I'm gonna scrape the current algae/slime and back down to a reverse 8pm-10am light cycle in that case
