Red algae I guess but.....

Hello guys,
I was not going to post about this but reading about it in the web made me realize that I may have a bigger problem than I thought.

I have some red algae, I do not have any pics of it but the following picture is the closest I can find in terms of the texture, but it may not be the same thing that it is showing in this picture….it is not slimy, it is not fine or cotton like, it is not bushy either, it is fine little defined strings….I actually got some with couple of my frags and removed it when it was time to glue the frags on their permanent spot…..so now I am seeing little strings here and there, I actually have a small dot on the back wall of the aquarium….my issue is I have 2 frags (different ones from the ones above) that have this algae next to them, the algae is not yet growing on the frags like this picture, but what I am looking at here in terms of danger to my corals or tank in general?

I can try to pull it, but like I said it’s not like clumps, or on the sand…..just as a FYI:

I do 15% water changes every week
Only feed once a day, only have 2 clowns and 1 cleaner shrimp
Phosphate is zero
I have about 10 or so cerith Snails, 10 hermits, 5 red hermits, 4 Nas.snails and a cleaner shrimp so I do not believe it is for lack of cleaner crew that it is not eating leftover food, besides, like I said, the strings are not growing on the sand at all and my clowns barely let any food go uneaten.

Thank you for your inputs

 

It sounds like Diatoms... Heres a link with more than enuff pics to id your problem... But first look at Diatoms and runn from there..!!

Good Luck..!!

 

could be diatoms or, Sounds like cyano if it is like a slime or hairy mine was both, covering, you can cut down on feeding, lesson the amount of time the lights are on,or even turn them off totally for a couple of days and add more flow directly to the effected area, but not to create a sand hurricane, i battled it for months and in the end gave in and use red slime remover, its been two weeks now and its still gone,

 

Hi guys, it is not cyano...it is not slimy, it is not growing on the sand..they are little single red strings growing, thicker than hair, like tiny branches...growing out of the rocks

 

gelidium or coelthrix.. spelling off tonight probably. Check the ID thread for correct spelling, it is late and I am lazy...

 

Gelidium

 

not that species of gelidium though, but yep. stingray is right i think
