Does anyone use both together? I been using GFO for a long time and wanted to start vodka dosing but read not to mix both. I just love GFO for low po4.
im dosing vodka with gfo...i read that to, but then later down the road i read somewhere else carbon dosing really helps nitrate level and not so much of phos so i thoguht i would try gfo...and my phos went from .5 with vodka alone to 0ppm over a few months.
Same experience here to. As I stopped gfo my Po4 cripping up, giving sps bad color. Run back again return back the color.
Granulated Ferride Oxide. Rust basically. It basically binds with phosphates to pull them out of the water column and usually is needed to be replaced monthly depending on the tank.
I took my gfo offline and am dosing the lanthium chloride again with pellets and my tanks are looking much better color wise.
Zeo tanks warn against using phosphate removers with bacteria driven systems and I'm seeing why although I cannot explain it!
