What should I do? There are 3 really small green balloons on my rock, I assume it is bubble algea. I know if I pop it that it will spread, so how do I get rid of it?[/QUO
Bubble algae will look like small round dark green balls - you can carefuly tease it off the rocks as it can be quite hard when larger but be careful not to burst it - I have a turkey baster on hand just in case to suck out any debris
