Ato

[Rmckoy]

I’m searching for a auto top off
But don’t want to buy something that’s going to either flood or fail

what’s a reliable but not overly expensive ato for a 90 gal ?

Everyone loves the Tunze ATO so haven’t heard anything bad about those. Personally I use the JBJ and I love them. Cheap and easy to install. You will have to find a pump with the JBJ. The Tunze I believe come with pumps.

Tunze. Not the cheapest option but it has the best reputation as an ATO. And this is where I'm not worried about saving a couple bucks. Your ATO is a critical piece of equipment.

I was already leaning towards the tunze but wanted advice .

I’ll contact my lfs ( coral frag store ) and see if they have one in stock

I changed to Tunze and seems way more stable and reliable

 

[Gernader]

I currently use Tunze ATO for mine. It is pricey, but you pay for its reliability

Tunze 3155 all the way. Second vote would be Avast Marine Works- I've only had it fail on me once (I've never had a Tunze 3155 make a mistake in over ten years).

Or this has been great for me

I use the Tunze 3155 Osmolator -- 3 years now and never a problem yet.

I'd recommend this one as well. Great unit!

I bought this as a whole set up to include the reservoir.

I like that the sensors have no moving parts and so far i have not had issues with the magnetic holders for the sensors.

It is worth looking at in my opinion.

does the 3155 have redundancy built in? I.e. mechanical float in addition to an optical sensor etc? If not, can that easily be incorporated to it? I would assume you'd need a controller?

@Rob.bucek Yes. I’m using the Tunze 3155 and it has an optical sensor and a mechanical float. If the float rises too high an audible alarm is triggered.

Thank you very much!

I'm looking into reefbreeders ATO. But no experience

Check out my post on EcolibriumReef, a DIY aquarium controller base on Arduino.

The controller has an auto top-off system that uses several redundancies to prevent flooding. A float switch will detect water level and trigger relays to open/close solenoid valves connected to an RO/DI system. Once the valves kick open, a timer is started. When timeout occurs, which means the float switch might be faulty, system will shut off and required a manual reset. Three solenoid valves, each controlled by a separate relay coils, two connected in series to the RO inlet to open/close water source, one connected to the RO outlet to direct water flow. If a float switch, a timer, three relay coils and three solenoid valves, all fail at the same time, you must have a really bad day.
More info can be found on GitHub. Let me know if you need help setting it up.

I have the avast system. works well for me. I could not find any complaints about it. I had a question, and got a quick answer. As a bonus for me, they are located in Virginia near where some family live. "Hey honey, can i get this new toy? Isn't that near your aunt?"

Yes, it has an optical sensor and a float switch backup system for redundancy.
You don't need a controller to control this ATO. I have a GHL Profilux but this is independent of the controller.

thank you!

I ordered a float switch with the avast as a backup. Since it is a peristaltic pump, and should not be dead- headed, i teed in right before it and ran a recycle line back to the reservoir.
