The idea of it being low flow areas are due more to food doesnít sit and rot in high flow areas because itís being pushed away.
Bubbles on rocks,
there are 2 types bubble algae so not to be confused
air/gas bubbles are usually found on rock and sand in new tanks releasing silicates promoting cayno , but can also be found in mature tanks after adding new items such as coral or rock (best remedy flow) a turkey baster also comes in handy to help blow off rocks while releasing trapped silicates .
green bubble algae usual cause low flow / piled up food and waste
best way to resolve add more flow for circulation . the use of a turkey baster during water changes blowing off crud also helps , so this crud can be removed while sucking out old water,
