Bubbles, bubbles everywhere

Hi All,

Have had a pretty rough time with my Nano reef experiment but am
starting to think I'm through the worst then all of a sudden I have
bubbles on the live rock....almost looks like there has been a dusting
of snow....

By rough time I mean I had a dinoflagellete bloom that nearly took out
most of my corals (thankfully they are now recovering) and definitely
took out my snails....the result is a little bit more green hair algae
than I would want - presumably restocking the snails will help with this
but don't want to do this until 100% convinced that the toxic "red tide"
is under control - I no longer get red dots on my arms if I put my hands
in the tank...nor do I get that itching feeling....anyone wants to know
how I got it under control I'll happily share....

Right now the issue is bubbles...and lots of them. They are not the
bubbles with the slime that I had with the red tide but I am assuming
that they are bubbles created by the green hair algae producing oxygen
now back under a return to a normal lighting regime - they are actually
appearing in the areas of less water flow so don't think they are coming
because of bubbles from the power heads.....Do you think I am correct in
this assumption or is there something more sinister at play?

I don't really need any advice on how to get rid of the algae or what my
water parameters are....already know about that and will replace my
clean up crew once I feel confident enough that they won't get poisoned
by the red tide bloom - it's almost been clear for a week now....but
what I really need to know is if this is going to be an ongoing problem
and how to deal with it....right now I'm just blasting the bubbles ever
hour or so with a turkey baster but they just keep coming back....

Any thoughts or suggestions greatly appreciated.

TIA
Gill
