I have a new tank setup about 14 weeks old, been dealing with a lot of gsa. mostly on the slower plants like crypts anubias etc. A few on the other stems but not so much. I dose 15ml of apt complete (mon, wed, fri)
50% water change

Ive dosed extra phosphorous in the past as it is one of the common causes but Ive almost emptied a bottle and it still didnt work. I also clean my substrate often for debris

any other tips?
