Hi, my 90yo mom decided she wants her 75gal (all glass) tank cleaned and setup. She tried to find volunteers, but I guess I was volunteered. 
Anyway, besides algae everywhere, there is this white stuff floating on the surface. I've had lots of aquariums, but haven't ever seen anything like this. So, (1) what is it? (2) can the tank be cleaned to safely introduce fish? (3) clean it with? or maybe (4) get a new tank? Thanks for your help
