2 year old tank, had algae battles before. Nitrate is 10ppm (I'm dosing as had double zeros and dinos-- which are now disappearing). Phos is 0.03 as I know you'll ask. All other params good and stable.
This had been slowly growing. Looks like grass. Doesn't look like bryopsis to me (I gad small amount 9mths ago, fluconazole sorted it). And looks too thin/tall for GHA??? One similar post here, but didn't resolve. Any clues? It clumps when you pull it out, but can't get all of it.
