plastic bio-balls ... are they beneficial?
Hey guys,
My wife has noticed that the Bio balls that we are using in our Aquarium are always slimy.
She asked her dad who is a Mechanical Engineer, and a Goldfish afficionado, about the Bio Balls. Well, accdg. to my father-in-law, they may seem Good Bacteria. However, Bacteria are still Bacteria.
Good Bacteria can also mutate into a Harmful bacteria. What can you say about this?
Is there any scientific site that will explain the use of Bio-balls? and its origin.
