first picture looks like a huge mass of tubes from feather dusters or vermitid snails... If they are hollow then you have no worries about that and even if they are still critters inside they are generally harmless

2nd picture looks like hair algae... keep it cropped and buy a couple turbo snails to help out

Those sort of look like colonial hydroids to me. Do they ever grow "heads"? Like tufts at the ends?

That stuff looks like bryopsis algae. It looks different from the "stems" in the first pic you posted. Are they different?

That first pic is hydroids.The only way I know of that will get rid of em,is laying the rock they are on outside for for a couple of months.And they are probably the worst pest you can get.They'll overgrow corals,sting fish,and can even have a nasty sting to humans.Especially if have a cut on your hands.

 

[chrisx420]

i think its 3 different kinds definitely 2 different i have no clue what it is never seen it anywhere before

 

[Dakwan]

My first real try at an ID and i failed :D

I thought hydroids but i couldn't find any pictures in any reference books i have that showed big thick tubes like those

can i scrub them off ? should i just take it all out n scrub it ?

 

[chrisx420]

only the first pic has those thick tubes on it everything else just looks like thick algae except for this one it kinda looks like the first one but just much smaller

 

[yote]

If you got something that can actually get hold of em enough to pull em loose,you might be able to scrub em off.A stainless steel wire brush might work.

so i took the rock out n scrubed it everything came right off except for this i also tryed boiling a small peice with this on it and it did nothing i pulled some of with my fingers but it was on thier REALLY good also scrubed it with a wire brush it did nothing should i just take out the 2-3 peices of LR that have them on it ?

 

[chrisx420]

i also found this whille cleaning what is it ?

 

[yote]

Have no idea what that is.
