Akinsendemus and they have flagellated zoospores.
So you scrub them off, then 1-2 hours later it reattaches to the tank walls.
Doesn't attach to the gravel or the plants unless severe.
You can turn off the flow, scrub and quickly vacuum any that settle or run a micro or a UV, do a large water change etc.
Once the tank balances out, this stuff goes away on it's own, I've tried to induce it with several things, no really luck. It'll hang on for a few weeks under very high light but I've seen it grow at 2 w/gal also in some tanks.
If you scrub, vac, turn the lights off for 2-3 days etc, that should kill most of it. Clean the scrub pad also after.
I dose 10-12ppm of NO3 every other day in my high light no fish plant tank, I don't have any algae. PO4 is high also, traces are every other day as well. 5.5 w/gal, 110 w on a 20gal H.
No fish, herbivores etc. No algae also.
Very stable tank as long as I add enough nutrients.
