Top off system: Tunze Osmolator Universal 3155 ?

[L2]

Does anyone have any experience with the Tunze Osmolator Universal 3155 automatic top off system?

I have a 12 gallon nano cube from jbj and i need to find a way to replace water while i'm away. it evaporate quickly in the summer!!

Thanks.

I just hooked up a JBJ ATO system. Using a 37g tank for a freshwater reservoir. Seems promising, but haven't tested yet.

Here is a detailed review & this one is in-depth as well.

I think $175 for an auto top off on a 12 gal tank is a bit excessive but Tunze does make quality products.

As austinsdad mentioned there are other great brands for auto top off. I’ve listed them below.

JBJ ATO
Tsunami Top Off System
UltraLife Float Switch
Reef Fanatic Level Controller
AquaHub Top-if-Off Kit Premium
