No idea.... but looks bad!

Hello, i am relatively new here but have a 4.5 month old reef. i am at the point were most of my algae is gone, coralline is growing, sps is happy, and water is stable. On my sand bed i have something very odd that i cant seem to find anywhere on the internet so far. I have little black tubes sticking up out of the sand... it looks like roots or stationary worms? I have tried to vacuum them with no success. i wont be able to post pics of my particular ordeal until Sunday, but i found a crude picture on google images, so i will try and post it. It looks really bad as if my sand has detris all over it.... its the only thing that is holding my tank back as far as looks goes, please help!

s.g.- 1.025
temp- 80F
ph-8.2
calcium- 420ish
kh- 9
amm- 0
nitrite-0
nitrate-0

1 clown
1 blue damsel yellow tail
1 peppermint shrimp
1 sps green birdsnest
1 lps frogspawn
1 lps red goniopora
4 narcissus snails
4 astera snails
3 margarita snails

 

after a few hours of searching that is the only picture i could find that looks about like what i am dealing with.

 

hard to tell without a good photo.
bump : )

 

They should cause any problems in your tank besides being unsightly. You may need to cut back on your feeding to thin them out.

 

i am feeding less the past few weeks, running gfo, and have 60x turnover flow

 

It may take a while for them to thin out. Hang in there.

 

I too have them on both live rock and sand substrate. I did googled "root like thing on live rock" but so far no luck anyone got correct ID for it.

yay i am glad i am not the only one, i have had them for at least 2 months....

 

did you notice them growing on live rock too? because mine started at live rock and slowly moved to sand. my wife thinks that's how rock become live ...lol

I will post pictures tomorrow once lights are ON
