Garrett Posted February 18, 2013 Share Posted February 18, 2013 I've noticed a green/yellow growth (very thin and growing ontop of rocks where light is hardest) spreading in my tank. It is a 36gal bow 4xT5HOx24W/each with 50Ibs live rock set up for 2 months, 1 damsel (yellow tail), 1 firefish, 5 small hermit. Can add photos if someone walks me through it. Im on mobile posting this and dont see an option. First timer here. Quote Link to comment Share on other sites More sharing options...
Juiceman Posted February 18, 2013 Share Posted February 18, 2013 you have to use the full site on your mobile to add photos. Pics please Quote Link to comment Share on other sites More sharing options...
+KimP Posted February 18, 2013 Share Posted February 18, 2013 Pictures would be a big help. Sounds like sponges though, which are a beneficial filter feeder. Quote Link to comment Share on other sites More sharing options...
esacjack Posted February 18, 2013 Share Posted February 18, 2013 how long has the tank been running? Algal films green and red will begin to form in the areas with high light and mid flow. High flow areas will generally develop a violet/red type of algal growth which to my understanding is another variant of coraline. Most of the time this type of growth occurs in new tanks, new rock, or a change in flow/lighting, or nutrient content. As Juiceman said, pics would definitely be helpful.

Yeah, I hadn't really thought about sponges, but its also a definite possibility. Quote Link to comment Share on other sites More sharing options...

esacjack Posted February 18, 2013 Share Posted February 18, 2013 its just algal film and coraline. In about a week or two the green will either fade, get eaten by a snail, or coraline will start to form. Quote Link to comment Share on other sites More sharing options...
