I currently have the np reducing biopellets running in my main display to combat a GHA and bubble algae situation. I've been doing some reading on vodka dosing and decided to get some input on this method and probably give it a try. I'm not too sure if anyone here employ either method so I was looking for some input. I do have multiple systems so I will be trying the NP reducing biopellets on my main tank and the vodka in my frag tank and analyze the two experiments. *NB*The algae issue in my frag tank is no where near that as in my main display. I also wanted to know if it is safe to dose vodka and run biopellets in the same system at the same time or will one cancel out the other or does this spell catastrophe? Please share your experiences.
