ATO question....

What all does your RO feed to(top off, kalk reactors, storage tank...)? I'm asking this because you could get a bigger container for just RO storage, then have a smaller container with a feed line to top off and such. This way when you take 5, 10, 15.... gallons from the RO storage tank it will get replaced with larger amounts at a time(run longer). Does this make any sense?

 

I put a valve on my RODI holding tank. When its full I turn off the valve. When it gets near empty i turn it on.

 

Y is running the ro in short bursts bad?

 

Another thing that you can do is get a selenoid to use in conjunction to a float valve and put the selenoid on a timer so that it runs for a couple hours a day or until the float valve turns it off. That way it can be fully automated and you don't need to worry about turning it on and off....but if you're around your holding tank all the time and don't mind the manual, that's a great option too and cheaper.

I've heard running it in short bursts reduces the lifespan of the membrane.  I'm sure you could find more specifics on the FAQ page on the Air, Water, Ice site.

I have a selenoid on the input line before the ro that is hooked to a timer that turns the selenoid on and off my timer only turns on 1 1/2 housr a day

 

From the AWI page:

Each time you short cycle, the RO system feeds your DI cartridge much lower quality water than when your RO system is up and running. The lower quality water shortens DI resin life. If your system is pump driven then you risk ruining the pumps and hammering the system to death, on/off/on/off 24 hours per day 7 days per week. Eventually causing fittings and pumps to fail or burst.

Search for them on Google. (http://www.google.com/search?hl=en&...f&oq=&aqi=) They are not stocked by many of the aquarium equipment places. You could also ask the Air, Water, Ice guys and see if they can order one for you.

This looks like a complete setup with an optional solenoid  Is this what we are talking about here for the most part?  http://www.fishbowl-innovations.com...Controller

 

Well when you decide to not be a tight *** get it and let us know how it works /DesktopModules/ActiveForums/themes/_default/emoticons/biggrin.gif

 

For the record I'll have 2 solenoids for sale at Fall Fest.

 

You can also get a solenoid at autotopoff.com  This place is also a girs sponsor

You plan on being in Des Moines sometime after fragfest snowman? I can always pick them up for you if you want me to.

 

Chris I think they are over $100, I read the same thing about short burst. I also filled my tank and re-filled when it was getting low. I bought a BRS DI resin chamber, and BRS neuclear DI resin. It has been in use for 4-5 months and holding a TDS of 0 as of last night! There is only about 10% of the blue left in the DI resin so I expect to change it out pretty soon. Either way $10-12 every 5-6 months is pretty cheap. I fill up a dedicated container weekley for my top off. I still use short burst of RODI and every once n a while have a drink or wash my hands off(to lazyfor all of the stairsLOL) Seems to work well and 0 tds...
