reread post 2 of you missed it
I have same results - see picture 1 and 2 only change was fix scrubber and wait 17 days.
Scrubber has been limiting / preventing / controlling algae growth in my display for 2 years. I don’t do water changes, I don’t have a skimmer, I only add fw top off and empty my scrubber every 7-10 days
Every 6-7 days I grow this in the scrubber. And in the display I do have algae but it’s like maybe a tiny tuft in an occasional spot, not noticeable unless really hunting for it
Scrubber is my only source of filtration
