Is it remove able or is the rock like bleached white?

 

[tanner1990]

It is definitely removable

 

[Jesse32]

Oh idk was going to say check ammonia but nvm if it's like an algae

 

[Jesse32]

New rock?

 

[tanner1990]

Nope rocks been in there from day one
I think it may be an algae maybe need more
Snails or whatever
I checked all levels today and did water swap yesterday

 

[Jesse32]

Yea strange I'm going to bed now lol ill research tomarrow at work see if I can find anything

 

[tanner1990]

Haha ok thanks

 

[Jesse32]

Couldn't find anything other then saying it could just be an algae sry :/

 

[tanner1990]

My friend told me it was coralline algae which is apparently is good
Not sure exactly what it is

 

[Jesse32]

Coralline algae is usually hard but if you can like shake the rock and it falls off or sucks off when you siphon it's something else

 

[tanner1990]

It only comes off if I scrape it it doesn't just fall off from the currents or anything

 

[Jesse32]

Oh okay yea it's prolly the coralline algae then good usually purple or green color that I've seen

Looks like bleached coraline algae to me, especially with it having to be scraped off.

What does that mean ? Good bad

Well I'd guess that would depend on what caused it to bleach. I haven't done much research or anything on the matter but I believe a change in lighting or parameters could cause it to bleach.

That looks like a type of sponge. Far as I know, not harmful.
