Aerating nutritients

[Allen C.]

I use Advanced Nutrients in Hydro. Should I be using an air stone to aerate the unused mixed nutritents I use to top off ?

I could be wrong but i dont think thats necessary. Maybe if you have beneficial bacteria...but even then idk. There is nothing to really take the O2 out of the water and the act of pouring will introduce o2 from what i understand (much like wind and wave action on the surface of a lake does). The question is how long do you leave the nutes sitting? As long as there is nothing organic in the nute solution then it should keep for a while.
