Great thread. I started keeping corals (with mixed results) when 0’s were the goal as keeping N/P down was a challenge. Now thanks to refined filtration methods that are so effective that now some people are dosing N/P.
Unfortunately a lot of the literature has not kept up and reefers are still aiming for 0’s. This kind of thread is important.
I believe that 0 has never been a goal in reefing. And I believe that many new reefers are interpreting ULNS wrong. And aiming for zero instead of Low nutrient, like the description says “LOW” not zero. Also I believe that a few years of experience would be needed before even attempts to run a system that way.
