Hey anyone know where I can get a sensor that would tell a Neptune DOS when to kick on? It would be used for auto top offs.

I use a simple float switch connected to a breakout box to accomplish this. I do not have access to my code right now, but I am sure @SuncrestReef has an article on using a breakout box to perform tasks and may be able to paste a simple code for you here.
 
You can use a float sensor connected to a breakout box, or an optical sensor connected to a FMM module.

However, the coding on a DOS is different than for controlling a basic pump. If you just use the typical code:

Set OFF
If ATO_Lo OPEN Then ON

this would only cause the DOS to run at 25 mL/minute, which is a pretty slow pace compared to a typical ATO pump. If you want it to run faster, then you need to create a Dose Profile as explained in my DOS tutorial:

Example:

Set OFF
If ATO_Lo OPEN Then DOS_Topoff

Also, read my ATK tutorial for more details on standard programming that incorporates extra failsafes such as a 2nd sensor and the emergency failsafe When timer:
