Thinking of starting GFO for phosphate removal

[DKoKoMan]

I guess to start with we would need to know what your nitrates and phosphates were sitting at. A refugium will reduce nitrates and phosphates (nitrates will be reduced more than phosphates). GFO is great at reducing phosphates and carbon dosing is another method to tackle high nitrates along with water changes.

Depending on what your numbers are, the most important is figuring out where the source of the high nutrients is coming from ie. overstocked, over feeding, lack of water changes etc. I know our tank is in a fallow period right now but prior did you test you nitrate and phosphates with a good quality test kit?
