cyano
 

i got mine from h2ocean salt-stopped using it and it went away-sand sifting gobies help or a sand sifting star-needs some movement over the sand

+1 right there, excess nutrients is usually the cause or decaying matter.i would remove what you can with a turkey baster and then increase your flow by pointing a powerhead at your sandbed.water changes will help reduce your nutrients and red slime remover will get it gone but if you dont lower your nutrients it will just return.cyano on sandbeds tends to mat pretty bad and a turkey baster will suck it up in one shot.


clean water and no dead spots is the key along with removing something that dies the minute you notice it:):)

if you do use red slime remover read up on it as its not always safe in the wrong hands, you will need to keep your skimmer running or possibly over flowing or run an air stone as it depletes oxygen during the night time:) cheers
