Osmolator Universal 3155 Auto Top Off - Tunze
Why does BRS recommend this?
Bulk Reef Supply tried many different water level switches and auto top off solutions before giving the Tunze 3155 Osmolater Universal Auto Top Off BRS Recommended status. Despite its higher price this is by far our favorite solution. Spending the extra money on a Tunze Osmolater will give you that extra peace of mind and insurance from having a disaster that ruins carpets or hard wood floors. For the value, and reliability it is hard to beat.
Max Head Height: 7.2 ft
The Tunze Osmolator 3155 is one of the safest ATO’s available. It utilizes an electronic eye sensor to monitor water levels and a backup float switch sensor with an optional audible alarm. The controller protects the quiet metering pump from running dry and reports an empty storage tank. Two magnetic holders for sensors and multiple mounting brackets included as well as a pump.
LED indicator lights the Osmolator will allow you to visually see if their are any issues with your top off system.
Two technologies of water level monitoring, and built in safety back-ups.
The optical eye sensor will keep the water level very steady to keep the salinity from fluctuating in your aquarium. The Osmolator does work well with kalkwasser.
Max Head Height: 7.2 ft
Note: With any pump, kalkwasser can cause premature wear. New pumps are available at a very reasonable price.

I have a plastic drum 26 1/4 height , 14 " D . Do you know the pump is enough pressure to push water vertically ?
Your best bet is going to be contacting Tunze USA for any parts.
They can be reached at 512-833-7546 or firstname.lastname@example.org.
Kalkwasser will degrade the life of the pump and is not covered under warranty. The magnet is fully coated and can be submerged.
It does come with all necessary items except the reservoir!
The pump has 1.2 meters of cable (~3.9'), the controller has 1 meter of cable (~3.2') that connects to the pump, overall you have roughly 7ft total. You can extend it with speaker wire if you have to, but you only have 9ft of hose with it. If you have any other questions let us know.
Happy reefing! c:
We appreciate your interest, but I'm afraid our distribution area is limited to North America and all of our equipment is wired for standard US 110v electrical.
Have a great day!
The power supply has 12V, 1600mA maximum output, connected to a watt meter with the pump running, the draw at the outlet is generally around 8W at 115V with the pump running. The entire system uses 1-1.5A at 12V depending on pump speed setting and head pressure.
This osmolator will run for typically 10-15 minutes in a dry container. eventually the controller will sense that it has not filled in a timely manner and should turn the system off. if this continues to not be filled there may be red flashing on the controller. For direct assistance you will want to contact Tunze directly!
The optical eye sensor will usually sense and fill within the range of 1/4" Feel free to let us know if you have any further questions!
Head pressure is the maximum height that the pump can push water vertically. If your tank is higher than the Head height listed this will not be able to work. Feel free to let us know if you have any further questions!
If you have calibrated the pump to maximum output and it is still unable to keep up you will want to ensure the pump is filling the proper amount. It may be that the head height (the vertical height the pump has to push the water) could be too high or other pump related problems. We have used the osmolator on larger systems with quite heavy evaporation with great luck. If the issues continue you will want to contact Tunze directly to see if the pump is working correctly! I have included their contact information below!

The 3155 will have 2 sensors the mechanical float and the optical eye. The 3152 will only come with the mechanical float switch. Feel free to let us know if you have any further questions!
This will be 4" long, 2.5" wide and 1" thick. it will require a Velcro pad to stick or to be used with double sided tape.
This will work great in the back of a nuvo 30! Feel free to let us know if you have any further questions!
The diameter of the pump is just under 2" this is how wide the cap will need to be in order to allow the pump to pass through.
The Tunze Osmolator is an entirely self sufficient system. It is perfectly fine to connect the Osmolator to one of the Apex's power outlets incase you wanted to cut the power for some reason (like when you are doing a water change) though the Apex isn't capable of reading the Osmolator's sensors or anything of that sort.
In theory it could present a problem but the circuitry in the Osmolator should help to prevent that. Every time the ATO is triggered it runs for a minimum of 15 seconds. It adds overfill to prevent short cycling. In most cases this should be sufficient unless the height of your waves is constantly changing.
That is correct. Its a submersible pump that gets stuck right into the top off water. If your interested in this ATO system you should give this blog article a quick read. It goes into a lot more detail on the system (which is one of my favorites).
The max head pressure on the osmolator pump is 7ft.
The max head pressure on the included pump is about 7ft. It likely wouldn't be well suited to this application. That said though, you can get the additional switch socket adapter which would allow you to control any pump via the osmolator system. That way you can use a pump that can handle the head pressure.
We run into very few issues with these but after that length of time I would imagine its possible for any component to fail. We don't have individual parts like the optical eye, but if you give Roger and company a shout over at Tunze USA, he might. At the very least he could likely help you narrow down exactly what it is. The number I have for them is 512-833-7546 firstname.lastname@example.org
Just wondering if I need 2 ATO. I know you can place it either in the sump or in the tank, but my question is if I place it in the sump will it also refill my tank in that process. I don't see that happening but if it does please let me know.
If you have a sump, it MUST go in the sump, in the chamber where your return pump is. This is the only area of your tank that will have a changing water level depending on evaporation (unless its far too late!). Only one ATO would be necessary but it must go in that location if you have a sump.
The pump on the osmolator has a max head height of 7ft.
The Osmolator actually comes with the pump right in the package so you don't need to buy one!
