Phosphates/Chemistry
First, good news--despite my failure to find SAE's that I can afford, since
I started the DIY yeast CO2 and switched to Flourish, most of my hair algae
seems to be slowly disappearing. It gets pale then goes away.
Now, the question. I have the wonderful good fortune of having a water
plant manager who answers my water questions via email, usually within
hours. Among the recent questions I asked him was whether they measured
phosphates. His answer:
Yes, we monitor phosphate, so as to limit
corrosion in the water system. Orthophosphate is held at
approximately 2 mg/l.
Could someone tell me what this means? Is this good or high. If high,
what do I do. I've read somewhere that excess phosphate can render
(liquid) iron fertilization nearly useless. Is this true?
