Whats growing in your overflow?

Hmmmm.... I inherited a 1/2 gallon jug and a half of Tech-M. My Mg is low and I've been waiting to refill my Ca reactor to help with it. Guess I need to do that and use the Tech-M! I also have some bryopsis, hair, and persistent bubble alges that don't seem to want to go away. I need to make some covers for the overflows too, found a whole caulerpa garden in there a while back (along with the hair, and bubble algae)...
