I had the same thing! I will be curious to hear replies. It was firm, smooth and full of fluid.

seaweed?

seaweed?

For sure

Picture is bit fuzzy to be certain, but it looks like a morph of Valonia.

looks like clusters of bubble algae to me

Decided to cover my overflow to keep out the light,should kill all of the algae growing in there ,right?

 

[billsreef]

Lack of light always works to knock back algae growth. Though you could always let the algae grow and harvest for nutrient removal, like growing chaeto in a sump.

If I decided to let it grow aren't I running the risk of it spreading to my DT when I pop the bubbles?right now it is limited to my overflow,also I cannot see if it's really gumming things up in there,whith chaeto at least it's where you want it.i was thinking of adding a small chaeto refugium( next reef stick on)

 

[elviraveloz]

I have them in my refugium for about a year and never spread into DT.

Green Bubble Algae. Don't pop the bubbles remove it.

BUBBLE ALGAE!!! This is one algae you don't want in your tank whatsoever! Don't pop them or they will spread like wild fire in your tank. I suggest you remove them manually without popping them. I would even suggest to disconnect the sump from the ds until you remove them all to avoid accidental popping and spreading.

Buy some emerald crabs...they might eat it if it sprouts up in your dt.
