Any good ATOs under 100$?

 
Interested in seeing any suggestions from others (I’m currently looking for one as well).

Have you seen the Aqua Duetto ATO? I think it’s less than $75 and I’ve seen more and more people using them lately.
 
I've been using a smart micro ATO for 4 years without fail and at least 10 vacations. It was around $80, not saying it's perfect but I'm not looking to replace it either..

That one is probably way better lol.
 
I've been using two JBJ ATO units for a few years and they have never failed me yet. They have 2 sensors so one will turn the pump on to top off and the other will shut down the pump if your container gets too low so the pump doesn't burn up. I use old maxjet pumps that I have laying around but any cheap pump will work. The are well under $100 pretty much anywhere. $66 on Amazon

I just got the Kamoer Smart One last month for $80, it works fine so far, no complaints at all.
 
I bought one of these setups for $45 and added a sicce micramouse for $19 and a 5gal all glass tank that fits next to my sump for $15. Works amazingly well.
 
I've been using the AutoAqua Smart ATO Lite on my 10 gallon build which runs about $70. I had a slight issue early on with it overfilling but once I got the sensor in the right place it's been working like a charm without issue.

I used this on my nano 20 and it worked flawessly.


You can also get the larger unit from them for $100.

 
Bought this for a trip I made a couple months ago and been in use ever since. So far so good. Working as expected.

 
Kamoer has one for $72 and another one for $78.
+1 on the Kamoer. I like having the secondary overfill sensor. It's not a Tunze, but at 1/3 of the cost. Pump is cheap and easy to replace. Have been using 2 of these for over 3 years.

ReefBreeders. I think the EXO is over $100 now but mine has been awesome for over a year
