ULNS are trying to come closer to these levels, and are still typically higher.
I try to keep my phosphate at or lower than 0.03 (0.028) which is still 6 times higher than 0.005!
Again, with Nitrates, I try to keep around 0.5 (less than 1.00), which is still 5 times higher than 0.1 of a natural reef level.
Great read though, but disappointed there were no "numbers" or ranges of nutrient levels (or I missed them).
Yes, there should be a balance, as with almost anything.[/QUOTE]
You need to read the references/footnotes to get them. And, I like RHF and respect him immensely, but I dont know that I can make a generalization of what NSW levels are for "reefs". They fluctuate massively due to locale and regional input.
