I was under the impression that you installed an ATS and all in tank algae disappeared without CUC, manual pulling, etc.I read this as - after the manual removal, the scrubber is then keeping the display algae under control/at a minimum going forward because it is growing, and thriving, in its established zone.
So, what are we debating here? That’s what we have been saying all along.
Your vodka dosing does not fix anything, it keeps things under control. If you stop, the algae will come back. Same with the scrubber, and I have tested this numerous times (not voluntarily) on my tank. Scrubber offline, algae returns. Scrubber online, algae is significantly reduced and controlled
At least that seems to be what @jda is implying.
