DENVER WATER QUALITY vs. RO Filter!!

[airforceman]

Ok so here is the the water report from my water provider which is Denver Water. (sorry mods, it is a link however it is to a .pdf file with no competition to SWF) http://www.denverwater.org/waterqual...ity_report.pdf scroll to the 4th page.
With this water quality do I still need an RO filter? Or can I just use tap?
I'd love an RO filter for re-assurance but was just wondering if I could use the Tap?
Thanks!

Here you go, compare natural seawater and think how many times you will add top-off and do water changes hope this helps.

AS ashamed as I am to admit it......
I use tap water . I have never had issues . I do use filtered water in the nano where I keep corals and invert . But the fish only is doing good with tap water

i'd never use tap simply due to the copper in the house, not to mention the copper levels in your denver water.

Using tap to make salt water is usually OK, but top-off water should always be RODI. Here's why: evaporation only removes the water from the tank, not the stuff that was dissolved in it, so that stuff remains behind. When you replace the lost water with tap water you are adding additional dissolved materials as well, so the total concentration of each item goes up, and each time you add tap top-off, the concentration goes up even more, and may eventually reach problem levels. RODI has, for example, 0 TDS (usually) vs the 172 ppm in your Denver tap water, so eventually the total dissolved solid level in your tank will rise as you replace evaporation with tap water.

I wont even friggin drink Aurora's tap water, I sure as hell aint going to put it in my reef tank

My house is 100% copper plumbing so I have to use RO/DI but the water in this city is nastier than what Denver shows. My TDS were over 300

You have one problem in common with us, Chloramine in the water. You should get a RO/DI with the additional cartrage for the Chloramine. Just the copper in the water will eventually build up enough to become a problem if it's not filtered

I think the issue with city water is consistency. You never know what or how they maintain the systems. I have to believe that variations of supply water means variations in the water being supplied to your home. Added chemicals, flushing lines, ETC ETC..........
I don't trust my well water 100TDS after the water softener.
4 TDS after RO unit.

i'm the same with my well water. funny thing is your water softener is adding salt to your system, adding to your TDS. what is your reading bypassing the softener?

I use Potassium in my softener and yep your right there are trace amounts of whatever you use in your water.
Don't really know never tested it. I do know that it is heavy with metals (iron). Lets put it this way, I know when the softener is softening any longer........

As much money as we shell out for our fishtanks, I still don't understand why people don't spend the next 150 dollars on a water filter. You should see the filters I pull out of my RO unit. NASTY and I used to drink the stuff!

Where can I get one and about how much am I looking to spend ?

As others have alluded -
It does not take into account your plumbing, sediment in the lines, rust in the lines, copper, chlorine, chloramine and anything else they decide to run through. Consistency is key. Salt mixes are already variable enough, I at least want to ensure the "base" is good.
FWIW, I also used to use tap water and had algae problems. What works in one area at one time in one tank, may be totally different the next house over.

Check out the filter guys their brand is pretty good. Shoot them an email and they'll show you how to set up something under your sink.
