Ok it does look like the pic in the first link, but the description of why it occurs doesn't make sense. It says low flow, lack of maintenance, low co2. I do 50% wc every week, pressurized co2 where drop checker is lime green by end of day, and the algae grows right in the path of my power head and actually waves in the current.
Could it still be rhizoclonium and what would you suggest to get rid of it. I have been manually removing it a few times a week.
