Boyd Enterprises ABE16708 Freshwater Vitachem for Aquarium, 4-Ounce

The description says this is safe for invertebrates, but I still want to ask about your personal experience with snails and shrimp? Thank you!

I just put 15 Drops in my 16 gallon and it looks like a snowglobe now. Why is that and should I return it?

Will this product have any negative effects with live plants?

Can this be used and benefit a betta? Does it expire ? Does it go bad if left unrefrigerated for a day? Does it harm plants?
