I am dosing my 2nd dose of Prazipro and since I have to turn off the skimmer and UV, I thought maybe I could kill 2 birds with one stone and go ahead and add in Dr Tim's One and Only bacteria. I started the tank with Fritz turbo 900 and I thought adding Dr Tims would mix it up a little. I did a little research and could not find anything that talked about it. Does anyone on here know or have done it before?
