Kind of looks like Red Valonia

 

[michellem]

Are they good or bad

 

[Tahoe61]

If enough nutrients are present most algae types can become invasive.

yea hard to tell from the angle if its valonia. Red bubble algae. Hopefully not. Most algaes with exess nutrients can be dealt with fairly easily. If its red valonia you probably want to take it out of the tank entirely before dealing with it. Ie peroxide dip. gentle removal and dont pop the bubble.

It's hard to see the shape from the angle if they're bubbles it looks like red calurpa. I can't tell if they are disc shaped or rounded. I'll post a pic or my red calurpa. I keep it in both my tanks. My glass needs cleaning (today but later) !
