ATO & AIO

[mrbee2828]

Hey everyone, I have 2 8g nanos I'm running at the house and I would like to add an ATO setup to them. I have a Smart ATO Micro for each. The backs are painted black so this will work perfectly with the magnet in the 3rd chamber. What I am looking for is a "U" shaped type fitting or something low profile to get over the thin glass and drop into that chamber. The Smart ATO has a 3/8" output and I am trying to drop that down to 1/4" black tubing. All the 1/4" airline fitting parts that I'm looking at aren't really going to work. I thought about bending ridged line somehow but I don't know if I can bend it sharply enough. Does this make sense? Ideal I'm thinking about the green Eheim U shaped plastic that comes with their canister filters. If I could find this scaled down it would be perfect. Thanks in advance for the ideas.

I use this curved tube for my ATO from a acclimation kit. You could just spray paint it black.

Looks like this might be the same type of deal:

It’s a bit wider arch than I want but if it’s put on an angle it can lie flat against the back I think. Thank you!

What about using black silicone tubing, (should be ok with the sharp bend) and using the appropriate barb adapter to fit the different tubings

I have bent the 3/16" rigid tubing, I just used a candle to heat where I wanted the bend then took it slow watching to make sure the tubing wasn't kinking.
