so i assume its ok to mix dsb, ecosystem, zeovit, and prodbio without any harmful consequences---at least ones that arent debatable
thanks for the links---that is one nice looking tank.
so, since these additives for prodbio come in little glass vials, if you break one open and use half of it to dose at a time, will the other half stay good until your next dosing time, or willit go bad right away?
