Can anyone I.D. these things.

I want to know what the yellow stuff is to the right of the RBTA. It has started to grow on anything that is/was white in the aquarium, mainly shells.

The green algae on the back wall of the aquarium. It is very thin. Hard to get off (kinda like coraline:lol: ).

Yellow sponge/algae encrusting rock. Fell off of zoo patch. Same color as yellow stuff shown above.

Lastly, is a sponge or coral in my zoo patch. Brown, leather-like. Get's covered up in day by the zoos. It's above/left of the disgusting hair algae I also bought

The fist pic is just normal hard calcerous(sp) algae. same goes for the algae on the glass. I have it and it slowly turns into coralline.

The sponge wont hurt anything, but I would pul the hair algae out or as much as you can.
