Need Help ID on 2 hitchhikers

[tref2010]

So a couple weeks ago i added about 22 lbs of cured live rock to my 30 gallon fowlr (will get coral eventually). I left for the weekend and when I came back I noticed a lot of purple stuff growing everywhere. Is this coraline algae?



Also on one of my live rocks I noticed 2 possible Hitchhikers: The first one is kind of hard to see but it looks like a transparent purple tube like tentacles. Possible anemone?


The second one: Looks like small pinkish red puffballs.


Water Parameters:
Salinity: 1.022
Temp: 76-79 about
Ammonia: 0 ppm
Nitrite: 0 ppm
Nitrate: 20 ppm ( maybe a little less)
Phosphates: No idea
Calcium: 400-450

Please help!

well the pictures didnt show up and the one that is there isnt very clear but as far as the purple stuff goes touch it and if its slimy prob cyano if its hard and on rocks its prob coraline. the red puffballs cant see to well but it looks kinda like red hair algae but i cant see to well post up some pics and maybe more can help

ok thanks. Is Cyano bad for my tank? To be honest I think it looks nice. I only have 1 clown and a couple red legged hermits.

pics aren't clear enough.. sorry. as jlong said.. if the purple stuff is slimy and can be rubbed off.. its cyano. if its hard and can't be removed easily.. coralline
purple thing with tentacles?? can't see well enough to id.
puffballs? maybe pineapple sponges covered in cyano??

here are some links that may help with id's

an anenome, tube like structure on newly added live rock...consider it a pest like majano or aptasia, either way, I would pull the piece of rock and get rid of it. The other, purple slime I'd say is cyano or some form similar that will eventually go away, but I'd be worried about that anenome type item.

in the first pic.. it actually looks like you have coralline algae AND cyano growing..
yes cyano is bad.. its cyanobacteria.
what kind of tank is this? how long been running? what lights? how often wc? you should test for phos, alk and pH.. are you running powerheads? what kind of filtration?
sorry.. lots of questions.. but need to know to help you further

Edit:
if you plan on owning corals.. you will need to bring your salinity up to 1.024 to 1.026

It is a FOWLR Tank, Been running for about 6 weeks and has just finished cycling, about 100w of lighting (Grow lights meant for plants, was told this would be fine), 15% wc a week, pH is fine, alk is around 1.7, and I have one power head meant for a 29 gallon tank. (I also have another pump for 20-50 gallons, should i use this?). I have two small HOB filters (buying canister filter soon)
Thanks for the help I dont mind questions lol

the hob would prob work best on your 29 imo u should get maybe another powerhead or two for more flow it sounds like its not enough if your alk is really at 1.7 your coraline will not grow or very minimal it needs it to grow its its food source as well as calcium and the amount or watt the light is really has little meaning what is important is the correct temperature of light you should run 10000k with a actinic bulb to get a decent par and recreate the natural light in the ocean ie get better growth and a healthier tank

New live rock carries in decaying material boosting nutrients. Cyanobactria love extra phosphate. It doesn't hurt fish but may smother other growth on live rock including coraline and corals. Manage phosphate to low levels via granulated ferric oxide or a similar adsorber, reduced feeding and cleaning rock surfaces via siphoning or brushing and it will wane.

Ok thanks I started dosing my tank with vodka last wednesday. My dose is at .2 ml. This should lower my nitrates and phosphates. Would vodka also help get rid of the cyano?

Ok thanks Ill get some new lighting lol

Would this be a good choice? I have 2 36" bulb sockets.
