Blue vet

Hey guys:

I only get red slime on the side of my aquarium that gets a lot of sun from
the sky light and only on the sand bed.

The LFS suggested vacuuming it up but because the sand is so fine I've been
hesitant to do that yet.

I've been using Blue Vet ~ Red Slime Control when the red slime gets out of
control. Seems to work amazingly and the fish/coral don't seem to mind.

I wondered what your opinion was on it. What is it made of and have any of
you had any bad experience as a result of using it?

Thanks.
