weird looking algae or something

[James Matthews]

started off looked like some apoxy or glue someone had put over one of my live rocks but I poked it with a stick and it was soft didn't think much of it till it grew tentacles, can't see it great took a picture and video but said it was to large to load

Don't really know where to look, is it the little red nub in the center of the picture?

 

[James Matthews]

in the center between the rocks the little milky looking tentacles, I have a better picture and video but it says to large to upload

 

[James Matthews]

right there

That definitely looks like some form of macroalgae but without clearer pictures it will be hard to identify what kind. Maybe some folks more experienced with macros can chime in.

It appears to be a cluster of sponges to me, what color are they?

It could also be some kind of pest anemone like Aiptasia. It’s really hard to tell from that photo.

Sponges, harmless

 

[Albertan22]

+1 harmless sponges. They are good filter feeders and help keep your water quality up and compete with algae.

what about the tentacles

what about the tentacles

Just different kinds of sponges with different forms

how do I get rid of and prevent the brown on my sand which I assume are diatoms, this is my first saltwater tank still learning

 

[Copingwithpods]

No action needed they will go away with tank maturity.

 

[James Matthews]

tanks about 16 months old

Oh hmm, have you done anything different lately that would spike your silicates? What are your nutrient levels at?

 

[James Matthews]

just tested nitrate, nitrite, and ammonia are all close to 0ppm and phosphate is between 0 and .25

 

[James Matthews]

checked phosphates again its 0 I was looking at it against my blue wall lol

 

[Copingwithpods]

Are you using api for those test? If you are bottomed out I'd wager dinos but let's not rule out diatoms just yet. Do you use rodi water changed your filters lately?

 

[James Matthews]

I use rodi water from the store by my house, he put in a $10,000 system and has to service regularly and yes api I know they are not perfect but they are pretty close to 0 on them
