| | Some general questions...
Having gone over the 'daily dosing' thread which is currently being discussed on this section, got me to thinking about a few questions. Perhaps some folks will chime in with their opinions/knowledge here.
A lot of talk about N/P ratios. Am I correct in assuming there is no one 'perfect' ratio, but it is all dependent upon one's lighting, fish load tap water, etc? So in general, is it advisable to tell the 'typical' individual to tailor this ratio somewhere between 8:1 to 10:1 and play it by ear from then on, by observing their tanks? From what Error has found, he implies that 5:1 might be a better ratio.
How much do fish waste and food contribute to the nitrogen and phosphates in a tank? Is there a type of food which is higher than another in this aspect? What exactly is a 'heavy fish load' vs a low one or otherwise?
It seems to me, these are important factors in determing how one doses. In my case, I could never measure a drop in NO3 from water change to water change, though granted I never used the top line kits. I have, what I would consider, at least, a moderate fish load, and I do feed daily. So I am curious in getting some idea of how much this interaction of fish/food is having on my levels and plant's needs. I now dose N/P at water change (10/1.25) and midweek (5/.625). So far, not much of any noticeable changes, and thankfully, I am algae free. I will up the PO4 on one of the tanks to see if has any positive effect (as Error found).
Just some ramblings/ questions out there for others to comment on.
