mine is in a platform over the tank. no light and bad angle.

Wonder if just putting a single cheap LED at the top shining down would make it more visible? (assuming you can't find a good float that doesn't get stuck to the side)
Anybody think of a way to put a sensor or float switch/s in this so I can keep track with my apex? Like short of drilling them into the side of the actual container? I was thinking of doing something similar also with my r.o.d.i. Container so when it got down to a point i could trigger the rodi unit to make more - instead of having it top off the rodi vat in small bursts as I do now with the mechanical float...

I have 2 float switches drilled into my container side near the bottom and top. They connect to my Apex to make decisions. I've found nothing cheaper or simpler.

That's probably the simplest. I could envision a means of having a float switch externally, but it would require a much larger tube than I used for my level indicator. If all you wanted was a float switch to signal 'empty,' you could mount a float switch on the end of a piece of PVC pipe and hang it 'upside down' from the lid so the switch was at/near the bottom.
I'm working on an arduino controller using a ultrasound distance range finder like this one to show the level in my ATO tank. That requires more than simply detecting an on/off switch, however, so I don't know if it would work with an Apex

If you can turn the distance to a voltage output, I think Apex can make it work.

Not directly. Arduino reads it by sending an initiation pulse on one pin then timing how long it takes the device to respond with a distance pulse. You then use a conversion factor to convert this time into a distance, so I think you'd have to interface it through an arduino to make it work. You could use an arduino tiny or something like that, but I doubt it would work directly with Apex

so you need an external discrete circuit that translates time to voltage. nothing with a controller,.. an analog or simple digital circuit
