No I don't. I don't know what is in there, so how can I say why or if it makes a difference. That's why I asked the question "How do you know that something else is not having an effect?"
Well if you want to play your game, then i'll play. Maybe you will see how it gets nowhere.
do you think that something else in zeobac is having an effect?
But, i will go one step farther and ask how and why you think that. Then if you could tell me what would be in there that could be added in such small quantities and still have an affect on established aquariums, i'd sure like to know what it is.
why hide it in zeobac?
why not hide it in another product? or better yet, why not make it it's own product so the manufacturer can make even more money.
Now, why do you ask questions like that?
