Re: Adjusting RO water

[Bob A]

Dave, thank you for this helpful info. Thanks to everyone who replied. I
also currently do 15-20gal changes in my 55g tank approx weekly. Hoping to
do more when I get the RO/DI set up. I have no form of added chlorine, as I
have well-water.

No way, I will not be drinking mine with the farming chemicals in the
well-water. Legally, they are above acceptable drinking limits, although
they say only truly harmful for growing people. I drink it sometimes, but
you can taste the crap in it. I'm looking forward to ro/di water for
drinking/cooking as well. Thanks

I _think_ the health dept says the no2 comes from the poultry manure. It is
a very high level. See my other post today. In any case, its there, and
using ro/di is cheaper than adjusting the well-intake. :) I understand what
you're saying though.

I hope the ro/di will work out well. There are probably chemicals such as
phosphates in the water too. I would be hesitant to attempt to titrate the
correct amounts of fertilizing chemicals from my well-water. Someone with
more experience might be more successful at this. Frankly, with the land
having been "corrected" with so many chemicals I'm not sure of, it wouldn't
work. I am told by my brother that things such as creasote, DDT, and even
worse insecticides than DDT have been used here. From the (close to)
inside, be aware of what might be in your christmas turkey. Heh

thanks to you,

"We?" Not for many years in my house.
