What I especially dislike is that it hypnotizes people to think in terms of target numbers. Entire religions are spawned around these numbers, just like in the religion of test kits.
Hi @ceg4048 Yes, but If you're a person, such as myself, with only rudimentary knowledge of chemistry and/or biology, I think its perfectly understandable why people get drawn in on "target numbers" and test kits. Unfortunately, there is an abundance of misinformation out there. For instance, such as that high levels of Nitrate or Phosphate causing algae. Take this quote from a very popular PO4 Test Kit, for instance:
"Ideally, the phosphate level should be zero in saltwater aquariums and freshwater aquariums or ponds, including those containing live plants."
... and of course if you do have above-zero phosphate levels they will sell you "remedies" to lower your levels...
If not for my personal experience of helping eradicating algae with very high levels of NPK (granted, in combination with other measures..), I probably would still believe in it, regardless of conflicting anecdotal evidence. With respect to livestock, I am still holding on to certain philosophies (or beliefs, if you will) such as trying to emulate the fish natural habitats with respect to water softness, temperature and to some degree PH, but I am only taking it as far as having those parameters in the ballpark and being much more pragmatic about it than in the past. Since I know approximately what I am putting into the tanks, the only thing I measure on a regular basis now (pre- and post WC) is the TDS (and temperature), but occasionally, I do the test kits as well.
