Tunze Osmolator Nano 3152 Information




The Tunze Nano Osmolator 3152 is an economical aquarium top off with more features than are typically found on competing units.

The Tunze Nano Osmolator is great for nano aquariums and tanks up to 55 gallons. Featuring a safe low voltage construction, it includes a metering pump, 3 meters of tubing, magnet holder for aquariums up to 10 mm (0.39") thick, power supply a float switch, protective shield and control unit.

For safety purposes, the Osmolator 3152 includes a processor-based anti-overfill system which turns the pump off after five minutes of filling if the level has still not been reached (equal to a pumping of approximately 0.75 gallons).

The Tunze Nano Osmolator 3152 was built in Germany and includes a 2-year manufacturer warranty that excludes the float switch—which features a 6-month manufacturer warranty and is user replaceable.

For larger aquariums, check out the Tunze Osmolator Universal 3155. If you need a container to hold your top off water, the Tunze Osmolator Storage Container 5002.25 is an ideal choice.

Noisy pump

Comments: Very reliable ATO that keeps my water label stable and a strong pump. But the pump is super noisy even when suspended in my ATO without touching the container walls. I replaced the pump after one year of use, but even the new pump is really noisy.

Comments: Bought this ATO for my 6 gallon pico reef. Works great and keeps my salinity levels in check. I gave 4.5 stars because the magnet holding the float switch kept slipping and twisting on the glass of my tank. My remedy was to put it on the plastic of my AIO filter and that keeps it from slipping! Other than that I would definitely recommended this ATO!

Comments: I don't recommend this at all. It doesn't have a run dry alarm. I had it for three months and the pump ran dry over a weekend away and it was toast. I replaced the pump and got another 3 months before it just totally stopped working. It's just just junk!

Comments: Item works just as it's supposed to. My only complaints are that there's all kinds of wires and its messy and It would be nice if the power supply and controller were sealed, and the float does not attach to the magnet very well you have play around with it.

Comments: This product worked OK for my 10 gallon aquarium for the first eight months. After about eight months it would start to overflow the aquarium The water level would make the float go up but the water would not shut off until a minute after the float had ou The water level would make the float go up but the water would not shut off until a minute after The water had already made the float go up. I replaced The float and still had the same problem. I think I may have shorten the life because my wave maker would make the pump switch on and off several times within a minute . I think this ATO would be best if used in a sump or aquarium without a wave maker .

Comments: Took a three days trip to San Diego with my kid and came back with my salinity went from normal 1.024 all the way to 1.035, out of 5 fish that I had four died. Been have to top off my JBJ NANO once a day for the pass 2 months. Decide to get this product. This is a great product. This is an all in auto top off, which comes with the pump, the pump fits in normal 5 gallons water container from your local fish store, you can make a hole on the cap of the water container and so you can prevent junk from going into your water tank. The installation is pretty easy, you might need an flat head screwdriver to install the water tube that clips on the tank(the tube where the water comes out of)the two electric wires needs to be split and clip on each electric wire plastic clip, not together(the manual doesn't show that). Normally I top off my tank once in the morning and once back from work, but this morning I look at the tank, water is still at the same level. Anyone who is having top off issue that has 50 gallons tank or lower should must buy this product, it will save you much trouble specially if you have rimless tank in a hot summer day.

Comments: This item functions exactly as described. Its extremely accurate and is keeping my tank at perfect water levels. The only thing I might say is that I went with the nano without thinking because I have a smaller tank. In retrospect I don't think the larger unit takes up much more space and has the additional failsafe of the optical eye. With the nano I would just check it a little more often but thats what they say to do anyway. Highly recommended!!!

Comments: This is the best ATO I have ever owned, very simple to set up and the pump fits perfectly through the water jugs opening. All I had to do was drill and cut a 3/4 inch hole in cap for the water jug and run the wires and hose through it. It rarely has to be checked on but Tunze suggest checking the float switch regularly.
