xxReidxx Posted February 23, 2008 Posted February 23, 2008 I was looking into getting a reverse osmosis unit to save money on buying RO/DI, but i do not want to go out and spend 125 bucks and a unit that does 25gpd when ill need about 2gpd at max. I was wondering if anyone has used this or knows if this will be enough clean the water

jamesnmandy Posted February 23, 2008 Posted February 23, 2008 what he is saying is, is there a cheaper method to filter the water properly when all he needs is a little bit per day my easy cheap answer is A. Walmart distilled water, $0.65/gallon roughly, have used it for a long time now because i am renting and do not want to setup a RO/Di setup until we get a permanent home B. i have read (have not done it myself but if i had a nano i would have already tried) using a Brita pitcher, just swap out the filters more often than they recommend for optimum water quality when i do water changes it's 10+ gallons, and top offs are easily 1/gal per day, so the walmart water is the best option for me right now since the closest LFS is $20 in gas away and costs .99 cents a gallon for fresh RO/DI

Most RO/DI units I have seen are between 50-150GPD which is wha they are capable of making at optimum pressure. The way it sounds you may be better off just using bought water. You can always buy one of those dual outlet RO systems for your sink and run the other line o a small container to store some tank water.
Reef-Czar Posted February 23, 2008 Posted February 23, 2008 just set up a 25 gpd ro unit....i have it conn. to my cold water for the laundry...i can disconnect when not in use
xxReidxx Posted February 23, 2008 Author Posted February 23, 2008 Sorry about that here is a link to it i thought it posted itFilter i was just wondering if this was a cheap alternative to buying a big RO/DI unit im only thinking about doing like a 10g ish tank i might do a 15 but thats only if i can get a good cheap filter
Militant Jurist Posted February 23, 2008 Posted February 23, 2008 For about $30, I bought an RO filter that screws right onto the faucet. I bought it at Bed Bath & Beyond, although I think that Wal-Mart sells them too. They seem to work great for me, and it runs about .05 per gallon, once you do the math.

Militant Jurist Posted February 23, 2008 Posted February 23, 2008 My screw on is good for 100 gal. That's a lot of WCs for a 10 gallon.
xxReidxx Posted February 24, 2008 Author Posted February 24, 2008 yeah a 10% water change is 1gallon and idk much about how much evaporation would occur but i dont think it would be more than a gallon per week if i have an acrillic or glass cover on top so im looking at 2g weekly... by theory, if it does produce 100g, it would last me 50 weeks so almost a year.
IdahoReef Posted February 24, 2008 Posted February 24, 2008 my easy cheap answer is A. Walmart distilled water, $0.65/gallon roughly That sounds expensive to me. At a minimum a pain to keep up on and a nightmare for trash and the environment. Like I always say though, "Life is full of choices." Every RO system I have seen is portable at some level, even if a small repair/replacement of an inexpensive pipe is required when moving. Then, if you are lucky (and I think most cw pipes are pretty standard) you could install the removed pipe and system in your new home. My system produces, optimally, 30 gpd. At 50% efficiency that would come to about 5500 gallons per year. At $0.65 per gallon it would cost $3575.00 to buy that water. Here is another thought. Use the excess production of RO water for your personal and cooking needs. You will NEVER go back to straight tap water again. I vote for the 25 gallon per day system.
Terestron Posted February 25, 2008 Posted February 25, 2008 ^+1 If you use 2GPD it would cost you $1.30/day for walmart distilled....at that rate you could of bought a $125 RO unit in 97 days....
