One of the major factors that has been affecting this aquariums stability is that it evaporates more water than I expected. For the past few weeks it seems that my daily practices included topping of freshwater during the morning hours before work and topping of more freshwater during the evening hours after work. So one of my primary goals in keeping this aquarium is water parameter stability. So I just received my Tunze Osmolator Nano that I ordered from Premium Aquatics. I went back and fourth between my decision of ordering this unit or the regular Tunze Osmolator Universal since the latter has the primary optical sensor and a secondary float sensor. But from reading this unit only doses water for a maximum of 1.8 minutes, so combined with only filling the reservoir with a limited amount of water I figured everything would be fine.

Since this aquarium is located in my dinning room my primary concern is to keep the misses happy by not making it an eye soar of tubing and cables. But I'm still aiming to have the equipment as accessible as possible. So I'm using 3M Command Strips rated for 16 lbs. to mount equipment and cable housing guide to hide cables and tubes when possible.

For the Freshwater Reservoir I am utilizing one of the 2.2 gallon Nutri-Seawater containers. I am searching for a nice wicker basket as to place the container in but for now it remains a little eye soar. The water cable and power cable for the pump are housed within a 3M Cable Guide.

The float switch which activates the unit is located in the far right chamber as recommended by Tunze. It was installed with the magnets that were included with the unit. Also the output of the water house is being aimed at the center baffles were there is a good amount of flow to mix the freshwater into the saltwater and then it passes by the heater to bring the temperature to the right level.

Great pictures! And excellent job keeping everything so clean and neat. Thanks for posting.

You are correct about the 1.8 minute limit and its purpose is exactly that: to keep from overflowing in case the float malfunctions.

For what it's worth and for anyone else who might read this, there's a jumper inside the controller that can be changed to allow for a 3 minute time limit. This is suggested for tanks between about 25 and 50 gallons, or other situations where evaporation may be higher than normal.

Yup forgot to mention that when I read the instructions. It's a great little unit.

You are most welcome. I actually didn't realize how much smaller this unit is from the standard Tunze Osmolator until I received it and set it up.
