cju84 Posted October 1, 2014 Share Posted October 1, 2014 Hey all - noticed some red plumpish growths on part of my rock. Is this cyano bacteria? I understand this is bad. If this IS cyano, do I just keep my lights off for a few days and try to remove it manually? I did my second water change since the tank's inception (3 weeks running) this past weekend. Tested levels tonight: ph: 7.9-8.0 ammonia: 0ppm Nitrite: 0ppm Nitrate: 20-40ppm salinity: 1.027 Thanks Link to comment
tibbsy07 Posted October 1, 2014 Share Posted October 1, 2014 Not cyano. Looks like a sponge or something to me. Link to comment
cju84 Posted October 1, 2014 Author Share Posted October 1, 2014 Thanks tibbsy. Would you guess that they are not harmful? Link to comment
D Z Posted October 1, 2014 Share Posted October 1, 2014 Those just look like harmless sponges. Good filter feeders. I would leave them be. Link to comment

I would leave them be. This. If it's cyano, you'll know. Cyano is more maroon/purple/red than those. It also grows like wildfire. It doesn't slowly creep. It pops up and then BAM it's everywhere in sheets of slimy, reddish-purple fury. Link to comment
