what are you guys using for ATO?

[ashrem]

1 gal milk jug and airline tubing with a airline valve.

I bought my float switch from another fmas member used but its a great switch.

I then got a aqualifter. Its quiet and used airline tubeing. IT works great.

Then I use a 5 gallon gas can from home depot. I dont use a float switch in the gas can and when it runs dry you will notice. I just make it a habbit to check every 2-3 days for empty. No porblems yet.

RO/DI unit (always on), 30 feet of 1/4" tube attached to my garage ceiling and a kent float valve on my sump.

when i do water changes, i drip the ro/di into a 55g can for a day or so.

dave, id rethink that setup if at all possible.

If the float valve ever malfunctions, youll be providing and endless supply of water to overflow your tank.

and having the rodi cycle on and off like that, youll be replacing your membrane in no time, as well as the tds creep.

YUP that's me too - the way i go about it now is I change the float valve q 3- 4 months-to avoid malfunction.
Options are plenty but I believe this is the easiest(perhaps) must prone to malfunction- u just gotta stay on top of it, and pray when u go on vacation all is well LOL.
Aother 0ption is a kalk reactor to do ATO daily- this way u a void the possible problem discussed above.

I've used the inverted gas can method for years.As I've upgraded tanks,I've simply up-graded the size/number of cans.They work on the same principle as a standard office water cooler.When the sump level drops,air is allowed to enter the container,which means top off water can flow out of the container.Once the sump level reaches the spout,top off water can not leave.There are no moving parts to fail & work purely on supply/demand .I use kalkwasser for all my top off,so every 6 months or so,the spout needs a soak to remove scale.The downside is,that on my current tank, I evap almost 3 gallons a day,so I have to refill the cans every other day.It is for this reason,that I have just purchased a Tunze osmolator & a reeftek kalk reactor & managed to pry- bar in a 20 gallon fresh water top off tank under the stand.
If your tank is not too large,you do not have a very high evap rate & you have a sump with a little overhead space,then I would use the inverted tanks for top off.I've tried to include a couple of pics to help explain the system.HTH

Pedro,

Here is a shot of my water container (pick up at www.tank-depot.com) also you can see my Nilsen Reactor w/magnetic stirrer. Sorry for the grainy pics, crappy a$$ camara to blame.

 

[pedromatic]

Thanks, compulou
That's very interesting. I found some DIY plans for a Nilsen reactor online. This might be a good meeting project for us cheapskates to discuss. I like to keep things simple if possible, and would rather not mess with CO2 and a calcium reactor.

I have 2 oceanus poseidons 1 is a older model and 2nd is a new pro series very nice units work very well. www.oceanussystems.com
