tarunteam Posted July 27, 2016 Share Posted July 27, 2016 So currently i've been buying Distilled water for my tank on weekly basis as going to my LFS for water is not a option. So my question is is worth continuing using distilled water or should i get a RODI unit? I usually go through 6 gallons of Distilled water a week at 1$ a bottle. So over a year i'll roughly spend 312 dollars on water. Is it worth switching to a RO/DI unit? Link to comment
cruiZe Posted July 27, 2016 Share Posted July 27, 2016 yes, absolutely. It will pay for itself in 8 months and you'll be getting better quality water... (do you have a TDS meter? When I used distilled it was 6-10 TDS which isn't horrible but 0 is much better) Now the debate of which brand to get will begin... Thinking about top off water and water changes, unless you have a 5 gallon or smaller tank, it's probably worth it Link to comment
VW_TDI_02 Posted July 27, 2016 Share Posted July 27, 2016 A fellow Hokie on here? I think that it would be 100% worth it. You can easily buy a quality RODI system for ~$150 and that's half of what you will be spending per year on water from the store. There are the BRS systems that are a bit pricier but there is one other place that is often highly recommended but I can't think of it off the top of my head. I'll look around and see if I can find it. [Edit] Found it. The site is SpectraPure and they have great deals on refurbished units. Since you're only going through 6 gallons, the filters and DI resin should last a long time. The only thing I would look up is whether or not your area uses chloramines. A lot of places are using that and they are tougher to get out. There are special blocks that help deal with them. http://spectrapure.com/Refurbished-90-GPD-RODI-System Link to comment
vegasgundog Posted July 27, 2016 Share Posted July 27, 2016 An rodi will pay for itself. I went with one from BRS that my local fish store carried. After another year I added the second ro membrane and doubled the water production, decreasing the waste water. Link to comment
Rural Posted July 27, 2016 Share Posted July 27, 2016 similar situation, whats the best small volume rodi system? plumbing friendly? Link to comment
AZDesertRat Posted July 27, 2016 Share Posted July 27, 2016 You will not find a better value than the Spectrapure for $112. Don't worry about any special carbons, they are not necessary, especially with Spectrapures high quality, low micron filters. Any 1 micron or smaller carbon block is more than capable of removing the chlorine portion of chloramines and breaking the bond with the ammonia which is removed by the RO and DI. Carbon does not remove chloramines contrary to popular belief. Link to comment
AZDesertRat Posted July 27, 2016 Share Posted July 27, 2016 Spectrapure refurbished system for $112. They come with a hose bib connector so you can get a faucet adapter, feed water adapter or like many of us a simple garden hose wye and hook it to the washing machine cold water supply for about $6.

dcullen Posted July 27, 2016 Share Posted July 27, 2016 I keep mine in the bathroom. I used a shower diverter valve and some fittings to connect to the supply line. SO my procedure is 1) place 5 gallon bucket in tub. Place hose from RO/DI in bucket, Put waste hose in drain. Turn diverter valve and turn on cold water. If I let it run too long it just empties into the tub, so no spills. Link to comment
AZDesertRat Posted July 27, 2016 Share Posted July 27, 2016 The first one is a limited time price on their best seller. The second is the same system with replacement filters, a handheld TDS meter and a chlorine test kit to monitor filter conditions and is an even better deal. The third is the normal price of the first. Link to comment
VW_TDI_02 Posted July 27, 2016 Share Posted July 27, 2016 Of the links you listed, I would actually just go for the middle one since you don't have the TDS meter and it's always good to have some spare filters. I have mine set up under my sink with a simple quick disconnect valve. Toss the waste water into the sink and good water into my brute trash can. Link to comment
gus6464 Posted July 27, 2016 Share Posted July 27, 2016 RO water is tasty. Making my own instead of driving to the water store to refill the jug for my water cooler has made by unit pay for itself already. And this isn't even counting the DI portion for my reef. Link to comment

Ultra pure water strips your body of minerals that you need to survive and can be deadly long term. Link to comment
AZDesertRat Posted July 28, 2016 Share Posted July 28, 2016 BS. The WHO has been trying to prove drinking ultrapure water is harmful for decades and decades but all their results are inconclusive. You cannot live on water alone and eating even one potato chip replaces more than what was removed in the water. Complete BS. Eat a healthy diet and drink whatever tastes good to you. You could not possibly do yourself harm. Remember 10-15 years ago during a contest a woman died from drinking too much water? She drowned internally, flooded her cells so they could not take in oxygen. This would happen to you way before you depleted any minerals or caused other problems, I hate seeing myths such as this pop up. We have drank RO in our home for over 25 years. RO/DI has a bland, blah taste, not refreshing to the palate so all you do is install a tee and valve between the RO and the DI and draw your RO only drinking water from there or even hook a pressurized drinking water system at that point utilizing a cheap 1/4" check valve to isolate the DI from the RO pressure tank so TDS creep doesn't shorten your DI life. Did it that way for about 15 years myself. Link to comment

The problem is when people only drink ultra pure water and no other water. http://www.isciencemag.co.uk/features/fact-of-the-day-1/ http://boingboing.net/2014/07/15/ultra-pure-water-can-kill-you.html Link to comment
AZDesertRat Posted July 28, 2016 Share Posted July 28, 2016 It is still bull. You need to do more research on the subject. I have seen posts and bogus articles like this for the entire 42 years I have been a certified water professional. There are a lot of quacks out there and there are sites totally devoted to water quackery and exposing them. Do your homework. Link to comment
gus6464 Posted July 28, 2016 Share Posted July 28, 2016 For starters I have a 3 way valve for my drinking water so when I make drinking water it's only from the RO membrane. It's not ultra pure water so to speak. Also I have tried RO/DI water and it tastes like shit. San Diego has sky high TDS and very hard water so people get their water from water stores which is basically just giant RO filters connected to taps. Link to comment
