I agree with flynruff a little surface agitation is enough for Oxygen requirements and that Phoenix water is fine for aquarium use, even drinking. I am a fan of running tap water through a charcoal filter, takes out the chlorine and copper; my tap water isn’t as good as yours. I like whole house filtration, cheap, easy and effective.
I spent a little time studying Phoenix water; the only things added to your water are flocculants to clear the water, which are removed, fluoride, for tooth health (or a plot to subjugate humanity by those in the hollow moon
) and Chlorine, Chlorine dioxide and Ozone.
Since Phoenix, water is surface water and there is no killing freeze cycle, there are high microbial populations and total organic carbon to be dealt with hence the Chlorine is dosed at a very high rate.
High Chlorine levels result in high, though by no means lethal by-products of disinfection. Haloacetic Acids
(chloroform, bromodichloromethane, dibromochloromethane, and bromoform)
are the big problems, though there levels are highly regulated.
Thankfully, charcoal filtration reduces these and any free Chlorine; this is the process better bottled water companies use
Total organic carbon (TOC) among other things reacts with disinfectants producing higher levels of disinfectant by-products (DSB). By law in the United States, water must contain at least 0.2-ppm Chlorine when it leaves for distribution. Chlorine dioxide (ClO2) and/or Ozone (O3), as disinfectant or oxidizers remove iron, manganese and destroy TOC, thereby reducing the DBS nasties.
Every solution of course brings a problem the use of Chlorine dioxide produces Chlorite (ClO2-) and while the regulations keep ClO2- from being much of a problem, charcoal filters do an excellent job removing it.
Ozone, produce Bromates, I confess the dangers of Bromate is unclear to me. It is highly regulated in drinking water but not in food. Still once again, charcoal filters come in the first run through activated charcoal reduces Bromates by 45%, second run reduces another 10% (50.5% total reduction).
The fluoride would require reverse osmosis (RO) to defeat the people of the hollow moon
This is more information than anyone wanted, I know, I just cannot help myself.
My recommendation to most folks is whole house filtration ($20 or so from the big box stores) at minimum two charcoal filters; in my house, I have a sediment filter in front of the charcoal filters. If you have a water softener, the whole house filters go before the water softener.
Your Phoenix water is fine for the system you have…
