So I have been using great white for years now works great but I have also used roots exc with great success. Well I go to my local hydro store today, and I'm standing in line and I ask the girl what's the difference between the two? she says one is a bacteria and the other is a antibacterial. I have already purchased both so if anyone has had this problem or knows how to use together I would greatly appreciate advice or input.
