we cure cyano and spirulina invasions all day long in the sand rinse thread, chem free, if anyone wants its a for-sure cure. we rinse it out and the feed that makes the slime mats grow
most large tankers wont do a skip cycle access of the sandbed...its for smaller tanks. but our method is much better than medication as it solves the cause and has a 100% compliance outcome, whereas meds range and allow growback by not removing the feed from the sandbed nor all the invader in many cases. this is no judgment against med use; if I had a large tank with a sandbed that could cloud upon disturbance Id use it too, it would take days to do a teardown cleaning of a huge system. more for smaller tankers.
Vibrant and bubble algae however go together very well, that species loved fragmentation regeneration and targeting valonia with vibrant is better than trying to scrape it out/spreading it. the tradeoff of valonia for cyano is 100% ok since cyano is terribly easy for smaller systems to be free of by lunchtime today.
