prepping for water change

[EngineerGoby15]

I have two 55 gallon drums and I make my water in mass, but im starting to notice floaties and what not and im just very concerned of what actually is going into the tank. Do you make what you need when you need it? I had it covered but forgot to cover the other day and if you do make mass do you run a pump constant? basically when do you go no way I am putting that water in my tank!

Thanks!

I keep mine covered and flowing. Unless you have largely dirtier air around the drums then you do around your tank then I would not worry about it.
