I have a small outdoor fountain that I would like to keep algae free, products need to be dog & cat safe. any ideas?

I can only say that this is non-toxic to fish and frogs. I don't know whether, if a dog or cat were to drink water that had this algae control in it, it would make the dog or cat sick or not. I would suggest you call the producer of the product. I use it all the time in my pond, and on one occasion I did call the company that produces it. Surely, they could tell you if it's safe to use around dogs and cats.

Is it safe for bees, when used in an outdoor fountain?!

I really don’t know. I notice that bees take water from a chlorinated pools and muddy puddles. Didn’t hurt my fish.

Can I use this in my fish tank

you could, but I wouldn't unless your tank is at least 150 gallons. Controlling the proper mix would be touchy in smaller amounts. There are better products for aquarium use to accomplish the same thing.

Can i use this in my 40 gallon tank? It does have the little moss balls

Yes, but reduce the dose to treat 40 gallons
