I have not read this whole thread, I am working through it but its long .... so this may be a repeat question. My 110g tank currently has a mild bubble algae issue. Mostly in places my Foxface cant get. Its mostly in holes and hard to get manually. I use a doser to dose 6ml nopox daily to control nitrate as I have a heavy fish load. I have been reducing that as my nitrates get under 4. I also run GFO and GAC most the time. Can I dose Redsea NoPox and use Vibrant at the same time. Also any issues with GFO and/or GAC.
