have got no test kits yet.
there was a tiny bit when i got it, could it spread just by having a little?
how should i tackel this bubble algae?
You desperately need test kits. Make them top if your list as the results can tell you an awful lot about how the tank is running.
should be ordering them tomorrow.
I'm pretty sure the same applies to bubble algae as it does with green hairy algae
got both when i brought it 
which means a good scrub and removal of nutrients in the tank. Get some rowaphos or phosban phosphate remover and dome seachems de-nitrate or add some cheato morpha for a more natural way.
would not know how to use any of them.
By adding these you will be removing phosphate and nitrate from your tank which deplete the algaes food source and should kill it off.
Best bet is to google bubble algae in a marine aquarium and that should come up with some results hopefully leading to further advice.
shalll do
Like nemo said regarding the emerald crab, would think Christmas has come early if you've got plenty of algae in your tank.
I have one in mine and he does a cracking job of keeping things clean.
would it be ok to add it now?
Rowaphos and di-nitrate is just simple filter media so place them in a media bag and either put them in a weir/sump/internal or external filter/skimmer/reactor etc. Or just contain it well in a media bag and hang it in front of a powerhead or anywhere with high flow for the time being.
i havent got any of that to put it in, but in time i will get a skimmer.
As for cheato. It needs light so as long as it's got that and in a place with high flow also then that should be ok.
ps- Cheato, apparently grows like wildfire so either contain it in a media bag or keep it trimmed. Dont expose it to the display side of your tank without some sort of barrier to stop it growing and spreading and to also keep any cuc or hitchikers from making it a tasty snack.
i might look into this
If your params are good ie zero amm, trite, phos and you have good ph then you should be good to add an emerald crab.
really? what would happen when i add more rock?
If you test for phos then take the result with a pinch of salt! [what a rhyme! lol]
As any algae would absorb the phos and keep it locked in so any phos result could be inaccurate.
If you have a large amount of algae on your LR then remove the rock if poss and scrub it in used tank water. Thats what I did and along with phos remover and a good cuc the algae should be gone in no time.
What kits have you gone for?.........Please say Salifert or API! lol
well it isnt alot, there is a fair bit of hair algae that came with the rock, which i didnt notice till in my tank gotta try look more carefully next time.
well atm i am looking at API kits
