red stuff all over tank

[jim_green_]

hello. i have red marron stuff all over my tank and rocks and pumps. Even my little crabs have reddish stuff on them. I cant even scrape the red stuff off.
WHat is this and how do get rid of it.

is your tank relatively new? If so this may be normal

if it doesnt come off easily it sounds like corralline algae taking hold. new tanks will go through dramatic color changes as this stuff grows with different shades of red , purple and green. if that is the case, it is very good to have

its relatively new.. a couple months old.. it looks odd especially on the crabs.
ill have to do a search on this corraline algea.
thanks

 

[saltn00b]

had your tank's rock work go from a uniform white color, to becoming covered in it ?

 

[saltn00b]

ALSO is it stringy, or velvety in appearance and texture? or is it just coloration

ya.. its difenately corraline algea from what ive seen in other pictures.
what is so good about it

will this hurt my crabs at all ? they got spots on there shells.

My bet would be red slime(cyanobacteria).
Did it cover everything relatively fast?
Does it wipe off real easy?

 

[jim_green_]

no it doesnt wipe off easy at all.. in fact im unable to scrub it off some of the pumps at all.
i do get some occasional 'slime' stuff.. but that vacuums out real easy when i do my water changes.

Man your lucky. Some people die to have some color in their tank with these beautiful red/purple coraline algae
