Weird macroalgae is taking over my rocks

[veliferium]

Have been experiencing the above problem for several months and boy do they grow fast!!

I am running Aluminium based phosphate remover, alittle under dosage as I'm afraid of overdose. And my skimmer is a JNS ConeS CO-1.

Nitrates are in almost non detectable at 0.5ppm

I would like to know of there are any natural predators of such macro-algae.

Many thanks

I don't intend to add tangs to my setup as it's only a 2ft

The other day I was looking at urchins, do you think they'll help? Cuz I have some hair algae outbreak at the moment as well.

Yes, hand removal is a pain in the arse chore for these algae

I have a tuxedo urchin, boy do they do their job, I had a rock covered in hair algae, just place them there and after a day all gone. My hermit crabs also help as well

The bubble-like algae looks like grape algae...

My initial guesses were on that as well.

But the vesicles on these are more oval than round and they creep alot(ALOT)!

I read that not much animals are willing to eat grape algae?

I had grape algae before and it's really nasty when it's dead... Real smelly...

True,had this once too I think it's because of over feeding...? When I stopped feeding too much,they just died out

Grape algae. The type with round bulbs are quite tasty for humans. The cone-shaped are toxic. You have both, but more of the cone-shaped. I have yellow tang, algae blenny, turbo snails - none eat this stuff. Great for human salad or composting. Like every other plant in your tank, they grow due to nitrates and other nutrients.
