Hi folks!
My 125G is currently a FOWLR tank.
A week-week ¹/² ago, my nitrates were approx 50ppm, per Salifert and API. I added a jar of Seachem de-nitrate into my HOB refugium (I'm running a canister filter and since the de-nitrate calls for a low flow, I put it into my refugium).
I just tested the nitrates again (Salifert and API) and they are at zero! Phosphates are at 2.0, per API. Nitrites and ammonia are 0, per Salifert.
I was always of the understanding that zero (or at least <0.2ppm) were what we thrived for. However, before posting this, I searched R2R and found some posts where people seemed to be concerned about zero nitrates.
So now, I'm confused. Should it be <0.2ppm, or not?
Does a reef tank require nitrates that a FOWLR tank does not?
