A recent SWCG install thread on the site prompted me to read my IC-40 manual more closely. In it, it very clearly indicates Pentair really doesn't want nitrates in the pool. They say no more than 10ppm and greatly urge 0ppm. They also don't like phosphates above 125ppb.
Using an API freshwater aquarium test, my nitrates are off-scale >160ppm. Using the Taylor phosphate drop kit, my phosphates are between 125 and 250 ppb.
The 2019 water report for Gilbert AZ indicates an average 3.6ppm nitrates in the fill water. They don't show results for phosphate. So I'm clearly going to gain nitrates due to evaporation.
I'm not worried about algae, I keep my FC well above the min. I'm worried about why Pentair is so worried about nitrates? Should I be worried? I presume draining is the only way to reduce nitrates. Is there a natural breakdown process for nitrates?
