My ato just broke probably because it was cheap, but now I need to get a new one, and didn't know if you guys had any good ideas. Preferably under $120 and the tank is 40 gallons if that matters, thanks.
 
And I would like it to be on Amazon if possible. So I don't have to pay for supper expensive shipping.
 
Tunze and RedSea have reliable ATOs. You can get free shipping on most of the reefing websites if you spend $49.99 or more.

ATOs play an important part in keeping salinity stable and having them fail while away would be very nerve-wracking. This is an area I would not cheap out on.
 
I've had good luck with this one,

LAZYBONE AQUA ATO Auto Top Off System NG11 for Saltwater Aquarium Long Life Design with Dual Optical Sensor for Both Reef and Fresh Tanks​

$34 on Amazon. I've had it running for a year without a problem. (I can't figure out how to add a hyperlink here that works to save my life 😛)
 
I’ve had auto Aqua smart ATO on my all in one for almost 2 years. Reliable, nothing has failed,etc. it’s 135 on bulk reef.
