Colorado water parameters

Looks like I'm moving to the Denver area soon. Curiosity got the best of me and I searched the web for some water quality reports. The reports show that the water is extremely soft (GH and KH should be <1) and very acidic (~5). Does this sound about right? That's going to be a major transition from my liquid rock, high pH water. Nitrates and phosphates also run very low.

They mentioned that zinc, iron amounts can run pretty high sometimes. What kind of problems should I expect with this? They also had silica readings, which is related to algae growth, and the "median of median" value they had was around 7ppm. Is that high, low?

Here's the report I used. It is of Park and Clear Creek Counties, which are just outside of Denver and is from 95-97. http://water.usgs.gov/pubs/wri/wri00...rir00-4186.pdf

Rolo,

What part of Denver. Where I grew up, Littleton (Denver water subsidiary) the water is fairly hard. In fact most of your run off water will be as the mountainess areas have high mineral content. A lot of Denver's water comes from Lake Dillon and such which is high in the mountains. I guess the water from treatment plants could be very soft depending on the treatment facility. I could probably still get you some rough readings if you want as I still have several friends in the area.

Really don't know where in Denver as of now. I might even end up in Colorado Springs or Boulder. But I do appreciate any info that you can get about the water.

I think all and all you'll have pretty good luck. I called a friend and he could only tell me that the Ph is about 7.4 where he lives. He doesn't have any other test kits, but will let me know if he runs accross any further info.

As far as a link goes, you may want to try this http://www.denverwater.org/waterqual...yreport04.html

Good Luck

Nice find. That site proved to be exactly what I was looking for. If you click on the 2003 "treated" water report, it will give you hardness, carbonate hardness, pH...all the good stuff.

There are 3 treatment plants, and from 2 of them the KH and GH run out at about 3-4. The other is softer yet. The pH seems normal in the mid 7 range, so the treatment plants aren't adding anything funky to the water. This means I finally should be able to breed apistos now.
