The common trigger is a spike in organic waste/ammonia. This may occur due to heavy usage of ammonia/urea rich fertilizer. (such as burying osmocote not deep enough). Dead livestock, poorly functioning filters, damaged or stressed plants can all be sources of ammonia. High light is an accelerator but by itself alone seldom trigger filamentous algae.

Unhealthy, deficient, or stressed plants (sub-optimal CO2, nutrient issues, overcrowding, transplant shock, physical damage, over-pruning stress, unstable or extreme tank parameters).
Abundance of old, deteriorating growth.
Spike in Ammonia/urea source in tank. (Due to improper root tabs, uncycled tanks, heavy feeding, nutrient formulas that contain Urea/Ammonia, dead livestock)

Replant healthy tops and discard old bottoms โ keep doing this till no more visible algae attachment to old growth. Prune off badly affected old growth
Mild cases would generally disappear by themselves as plant health and tank stability improves.
Severe cases can be killed off by Excel, or API Algaefix & other commercial algicides but base causes need to be addressed or the algae may return.
Solve underlying plant health issues โ this algae rarely occurs naturally without a trigger.
Water changes, clearing of detritus, old growth.
Plant larger, more robust, easier plants to increase plant mass in the tank.
