What’s Your Preferred ATO?

[BubbleAlgaeFarmer]

Go figure, i go away for a week and my ATO decides to stop pumping water. From what i can tell, it’s an issue with the float. Atleast this is what i can tell via a facetime call with my mother inlaw. So i ask, what is everyone’s preferred ATO. Looking for something that is very very reliable!

GHL profilux maxi doser with 3 optical sensors.

Yes yes. But you ask for it?

 

[BubbleAlgaeFarmer]

Isn’t that a doser vs being an ato?

I have 2 kamoer ATO’s, I’ve decided I’ll probably stick with them for life. One is 6 years old the other is 4 years old, both are perfect have never failed me in any way knock on wood.

I'm not saying it's the best, but so far it hasn't given me any problems for over 2 years.

I'm at about 10 years with my JBJ ATO.
I have about 4 on my Avast unit now.

My jbj ato gave out on me after 10 years earlier this year and I tried the nature dimensions smart ato. So far I’ve been very impressed with it. Seems way better quality that the $70 it costs.

My XP Aqua Duetto 2 is three years old. Had to replace the pump on it this year. Only issue I have had. Got the replacement pump for 13 bucks.

I have a tunze osmolator 3 and a kamoer ATO one 2 ST. I was a bit sceptical about using the kamoer so I installed that one with an additional overflow shut-off switch. I’m new so they’ve both only been running for about 4 months. Love them both, though.

I’ve got the older tunze 3155 on my main display and a newer osmolator 3 nano on my frag tank. Both quality kit IME. Nothing is perfect but these are both close. Tunze is a 3rd generation reef manufacturing company. Make trustworthy aquarium tech. Their skimmers, pumps, and accessories are all good from my experience and by reputation. @rvitko from Tunze USA is also very helpful if/when you need support.
