I think i have Cyano

if i do it's not much yet, it's at the top of the sandbed, the spots where i think i have cyano is where the sand is touching the glass. It's kind of a dark color, like a black/dark purple but hard to say. Not sure if it's cyano or i just need to move around the sandbed. I would take pics but my camera is dead and no batteries.

 

If it's just in one spot, try scooping it out.

 

it's in a few places, but only on the top that's pressed up against the glass, it''s on the front of the tank and on the side, i don't have anything that moves around the sand so it could just be build up. But if it is cyano i don't want to disturb it and make it spread even more

 

Don't worry, if it is cyno, it does a good enough job of that on its own. The best way to combat cyno is to keep what you put into the tank to a minimal, cut back on feedings, don't dose invert or filter feeder food. Clean you filters or sponges. If you can, run a phosphate remover and when you do water changes, siphon out as much as you can. I have had cyno for as long as my tank has been up. I have it under control though. It's minimal now. I have added a refugium with chaeto, am running a phosphate reactor and increased my flow. I also siphon whatever I can out when I do water changes.

 

ok thanks for the tips, i just did my water change yesterday so won't be doing another until next weekend so i'll try to syphon it out weather it's cyano or just build up from not being moved around
