Hey everyone I've got a problem that started out small and just slowly got out of control. I noticed a while back a red velvety growth in one spot on my sandbed. I didnt thinbk to much of it at first because it was so isolated and didnt seem to get any bigger. However due to a big change in my work and several family issues, I was forced to be away from home for quite a while. My tank is a 30 gal FOWLR. Now that I am back home I need to deal with this because whatever the red velvet growth is, it covers about 75% of the surfaces in the tank at this point. I have 2 damsel fish and they do not seem to be affected by the red stuff at all. I will try and add a picture as soon as i can to give assistance in identifying the red growth. But for now i would just say it looks like a dark red (maroon) carpet. it has a fuzzy or velvety appearance. Its basically a reddish carpet that has smothered my live rock and sand bed. I know you may not have much assistance available until i get a pic posted but i wanted to get this info out there. Any help is greatly appreciated. Thank you all so much!!
