Yes ozone is superior imo. That pic i posted was ozone not activated carbon sorry. If you want to kill bacteria safely a uv sterilizer is the best option at a slow flow.My tank has 0 yellow tint. I change my carbon a lot.
I read a thread that ozone was superior to uv in achieving the cristal clear, no water effect. That’s why I posted here.
I don’t believe my tank needs yellow reduction, but rather removing/killing the free floating bacteria is what gives me the 0 water effect IMO.
Ive dosed h202 in my 120 bare bottom when I had dinos. I dosed 10ml of 35% food grade. This stuff left a white spot on your skin if you get it on it. Very dangerous. However i watched green algae on the glass dissappear in 5 minutes without cleaning it. Also my fish had bubbles coming off their skin. I could watch a reduction in dinos hourly. But they always came back! No fish died but are huge fish, not little ones. Imo h202 is best left outside on the rocks spot treating.
