Dreichler Posted October 27, 2015 Posted October 27, 2015 Basically the title, i know practically nothing about them but they make RO water.... how is it setup, requirements, chemicals, etc... would it save me money to use my own RO and make saltwater myself rather than go to the LFS and pay $10 a week for 10g of saltwater and 5g of RO? Just some basics of how it all works...
jbb Posted October 27, 2015 Posted October 27, 2015 I run this exact unit (yes a refurb) it has been great , and the only way I could tell it wasn't new was due to the fact that the original box was missing . http://spectrapure.com/Refurbished-90-GPD-RODI-System

disaster999 Posted October 27, 2015 Posted October 27, 2015 If your paying 10 bucks a week just for salt and water, I would definitely pick up an RODI unit and mix the water yourself. Like the video said, you have control over the water quality. You never know when your LFS changed their filters or if their RODI is really reading 0TDS

Yes you use that water to make more salt water. The gallon per day rating is telling you how many gallons that unit can produce in a 24 hour period , therefore the higher the number the faster you can make water. On my 65 gallons I make roughly 30 gallons per week. That covers my water changes as well as my top off system . For the price You really can't beat the system that I gave you the link to and that's probably what I would go with personally For the tank you have.

jbb Posted October 27, 2015 Posted October 27, 2015 what would i just run it maybe like the day before my water change, or do i just buy like a 50 gallon "bucket" of some sort and constantly have it going I make all of my water on Sunday mornings and then do my water changes Sunday afternoon. I plan to buy a 30 gallon reservoir sell it once and just use it throughout the week. It really depends on the space you have available you can Google water change station and then go through the images and get an idea of what other people are doing
blkhwkz Posted October 27, 2015 Posted October 27, 2015 I have the same refurb unit and a JBJ RL-45. I do an 8 gallon a week water change on the tank. I have a Biocube29 that I do a 5 gallon weekly change also. Between water change and top off I am using about 16 gallons a week. I keep a 32 gallon Brute filled about 3/4 of the way with water that I use as needed.
braaap Posted October 27, 2015 Posted October 27, 2015 I use a 33 gallon Brute and a float switch shutoff. I put a horizontal float at the bottom of the brute hooked up to my Apex. I get an alert when I have about 5 gallons left so I flip my RO/DI unit on and it fills the brute in about 6 hours. The float turns off the RO/DI so it doesn't overflow the brute and I just shut the valve off once I don't hear it making water any longer. I use the brute as my top off container and my storage for RO/DI I use to mix new salt. I make 30 gallons every 8-9 days.
AZDesertRat Posted October 27, 2015 Posted October 27, 2015 You can keep RO/DI water almost indefinitely as long as it is sealed or covered as in 5G buckets with snug fitting lids, trashcans with lids or I also use 5G drinking water jugs and lids or I get the blue cube style camping or RV water jugs at WalMart that hold anywhere from 5 to 8 gallons and stack in an out of the way corner or space nicely. It is better for the RO/DI system to make larger batches of water, say 5 gallons plus, versus multiple short filter runs or small batches. The longer you run the system the better it flushes itself of the built up TDS or dissolved minerals via the waste line and flow restrictor. When you make small batches something referred to as TDS creep comes into play and this TDS creep exhausts your DI resin faster and eventually plugs or fouls your RO membrane.

AZDesertRat Posted October 27, 2015 Posted October 27, 2015 No. A RO or RO/DI system needs to be in a climate controlled place away from temperature extremes and bright direct lighting. It works well in a laundry room where you have access to the washing machine cold water supply and a drain, under a kitchen or bathroom sink or even portable by using a faucet adapter. I prefer mine hooked up all the time but portable is fine too as long as you leave water in the canisters when it is disconnected and store it where it is safe.
