Blubbernaut Posted February 19, 2013 Share Posted February 19, 2013 I top mine off w/ only 1 or 2 gallons when I see that it needs it, as I don't have much evaporation Quote Link to comment
cpetrosky Posted February 19, 2013 Share Posted February 19, 2013 hamster bottle ATO for my 3 gallon pico and manually for my 24 nano. Quote Link to comment

Hart24601 Posted February 19, 2013 Share Posted February 19, 2013 JBJ ato with aqua lifter, love it. Quote Link to comment
fishfreak0114 Posted April 23, 2015 Share Posted April 23, 2015 I top off by hand every few days. Not much evaporation in my biocube. Quote Link to comment
Sancho Posted April 23, 2015 Share Posted April 23, 2015 Wow a 10 year old thread. Tunze nano ATO on my CAD 8. Tunze osmolator 3155 on my 34 and 90. The 8 and 90 are near my kitchen so I have a ATO reservoir with a float valve connected to my RODI. Those 2 tanks are truly automatic. The 34 I may as well be doing by hand as I am filling the reservoir almost daily. Quote Link to comment
gulfsurfer101 Posted May 17, 2015 Share Posted May 17, 2015 This thing seems to do the job! Quote Link to comment
Sunstar Posted May 17, 2015 Share Posted May 17, 2015 DIY ATO for my 1.5 gallon. Gonna build two more this summer. Quote Link to comment
squamptonbc Posted June 29, 2016 Share Posted June 29, 2016 Old fashioned way, line drawn on the side of tank with a marker, and top off manually as needed. Eventually I'll get an auto top off, but 125-160 CAD$ seems a bit steep for something I can do manually for free.... Quote Link to comment
davidinnes Posted January 19, 2017 Share Posted January 19, 2017 I have two small lines drawn in the upper right corner on the tank glass with a marker. Low one is where I turn on the dosing pump, high one is where I stop it. The tank and dosing container are both checked for salinity before hand, and adjustments made accordingly. The "on" is via voice command to "Alexa" and a smart plug. The off is preset in the smart phone app to allow only 20 minutes on time (this arrived by observation and testing and the drip rate). Works well for me. Quote Link to comment
MainelyReefer Posted January 19, 2017 Share Posted January 19, 2017 Home made vacuum regulated top off, I plan on putting a few together and seeing if I can't sell them as the market is open for a new cheap ATO product Quote Link to comment
VictoryBell Posted March 27, 2018 Share Posted March 27, 2018 I top off by hand, once in the morning and once before I go to bed. Quote Link to comment
