So I have my 20g nano tank that is roughly 4 months old now and I have a pretty good breakout of bubble algae and sea lettuce growing everywhere. The lettuce looks like ulva which I guess isn't that bad since its a macroalgae but just doesn't look appealing in the display. I figured maybe a lawnmower blenny could help out with this, but then I started getting the bubble algae in a lot of places. I have seen people recommend emerald crabs, manual removal with a siphon, and vibrant.
I was wondering if anybody has had any success with these methods, I wish I could just try manually removing it but I know they say that popping them might let the spores release, but then others say that's only a myth and they need to be a decent size in order to actually have spores to release. Vibrant does sound good as it would also melt away the lettuce I think with a good amount of dosing, but then I hear many drawbacks of vibrant including cyano/dino outbreaks after, corals dying, etc. and just really trying to figure out what to do about this.
Any feedback would be great!
