Salinity swings are no big deal. I often pour in an amount of RO water equal to 5% of my tanks volume and I've topped off even more than that with no bad effects.

I can easily see how you could set up a storage tank that you refill when it gets low and set a powerhead inside the storage tank to top-off the reef each time the timer turns it on. But 20 feet is a long way for a little powerhead to pump.

There are easier ways to do this.

Have you heard about the "Glug Jug" for automatic top-off Works like a charm.

Question about your current setup. If you forget to turn off the RO can it fill the sump and overflow

Using that shut off that Mark suggested will still do the same thing with or without a storage tank.  All that has to happen is the pressure builds up and then it shuts off the source water.]]> Thu, 27 Jan 2011 13:03:59 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=46268&PID=397035&title=ro-di#397035 http://www.utahreefs.com/forum/forum_posts.asp?TID=46268&PID=397033&title=ro-di#397033 Author: ReefAddict

Thanks. I am not using a holding tank. My RO system is down stairs directly under the tank. I have a 20' tube running it up through the wall and prettied up with a faceplate. The tube is over my sump. I was going to try running the RO water on a timer, but don't want wild salinty swings. ]]> Thu, 27 Jan 2011 12:58:46 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=46268&PID=397033&title=ro-di#397033 http://www.utahreefs.com/forum/forum_posts.asp?TID=46268&PID=396643&title=ro-di#396643 Author: vadryn

Yes - that's exactly what mine looks like.]]> Tue, 25 Jan 2011 14:07:07 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=46268&PID=396643&title=ro-di#396643 http://www.utahreefs.com/forum/forum_posts.asp?TID=46268&PID=396601&title=ro-di#396601 Author: Mark Peterson

Yes, waste water continues to flow.

The better unit to use is the one that shuts off the source/supply water when RO water is not needed. This may be what vadryn has.

Found it in the first hit. The $20 unit turns off when RO pressure reaches ~65% of incoming city pressure. http://www.waterfiltersonline.com/auto-shutoff-valves.asp

My system has an auto-shutoff that kicks in when the storage tank is full.  Is there a storage tank in line with your setup?]]> Mon, 24 Jan 2011 15:09:05 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=46268&PID=396419&title=ro-di#396419 http://www.utahreefs.com/forum/forum_posts.asp?TID=46268&PID=396333&title=ro-di#396333 Author: ReefAddict

Correct me please. If I use a solenoid to shut my RO/DI water off at the sump, is waste water continuously created? Obviously I can test this theory at home, but I'm not home.
