DIY ATO

Reef Hub · Jul 6, 2019

hello all. So I’ve finally settled on an ATO that works great with my system. I tried the tunze Osmolator and it was great until my Refug light kicked on at night then it wasn’t consistent throwing my salinity off. I ended up going with a standard float valve, wired it to the Apex breakout box, and have the Apex powering on/off a Tom’s Aqua lifter. Been working great so far for the last 48 hours. Also seems a lot more consistent since everything flow through 1/8 ID hosing.

What I need help with is finding a special quick Disconnect fitting. The Tunze Osmolator has a special clip that allowed you to connect/disconnect the ATO pump pretty fast and easily. I’m hoping to get my hands on something similar for the standard float valve I installed so I can disconnect/reconnect the float valve with ease to the breakout box when I need to take it out for maintenance. Essentially I’m looking for a fitting that would be similar to the what the Tunze 3155 ATO pump uses, but something with a standard male and female end that allowed for quick disconnects between 20g wires would work too.

Any ideas on special clips for this? I’ve researched it and have not gotten very far.

I’m having trouble understanding the system could you send some pictures.

Essentially I have a float sensor that sits in the sump using a sensor like below. That sensor is connected to the Apex breakout box and the Apex turns on and off the ATO pump based on its position. It’s working great. I’d like to cut the sensor wires and add quick disconnects so I can remove the float sensor from the sump and clean it. I can’t seem to find any. The Tunze ATO control box use similar fittings to connect the pump.

Attached are a couple photos from Google. Hope this helps.

The float sensor is similar to what I run and the fitting in the photo is similar to what I’d like to achieve with the sensor. I’d just like to be able to disconnect this sensor every month from the fitting versus removing the entire breakout box to do maintenance.
