hi all
I used to dose/add additivies but now just change water. I see that changing water regularly seems to work for me than dosing. I am just wondering why dosing? Is it to make the water quality last longer (maintain) replacing the need to change water regularly? I ask is because l too heard about the good stuff like grotech etc but have not try it yet.
Just wondering if I dose regularly, do I still need to change water (to freshen up the water quality)? Pls advise.
