Re: Adding bleach or water purifier to fresh tank
Reply #8 –
The 2nd video is a little dated, however it is still one of the better ones out there. According to this, and other sources, 1/4 cup for 15 gallons. So...2 cups of bleach for 100 gallons should be fine.
"Mix one cup of bleach to four gallons of water for a 40 gallon tank, one and a half cups of bleach to six gallons of water for a 60 gallon tank, and two cups of bleach to eight gallons of water for a 100 gallon tank."
Allways dilute bleach as video shows before pouring in tank. I use the same hose from my winterizing hose kit that I added, to add the diluted bleach.
Simple 2 minute video.
