Iíve been doing research and found that adding sugar or vodka can lover the nitrates in my tank. I also have a refugium with chaeto but the chaeto floats to the top and dies out and dies. Any thoughts or ideas on what to do
levels like that your chaeto should not be withering away, if anything quite the opposite. Chaeto does naturally float, so thereís no concern there. Light and flow will provide chaeto with what it needs to thrive and in turn will lower your NO3
That said, what fuge light are you using, and also what are your PO4
levels testing at?
Speaking from experience, my Biocube 32 pulls about a softball size of dark green chaeto every 2 weeks and keeps my NO3
levels undetectable to where I need to dose 1ml of NO3
