Neptune auto top off failing

the pump will still run if the float if up /closed but no water will get into your sump once it's all the way up.
prevents overflowing basicly. sounds like some kind of electronic issue with the sensors, best to contact apex directly they will take care of you quickly.

good luck!

Oh I thought it was supposed to turn the pump off. Good to know.


I contacted apex support. Always seems to be something going wrong for me...

I had been keeping freshwater tanks since I was a kid. Most I have had break was a light and a clip for one of my external filters.


In 8 months or so of reef keeping, I have lost 2 power heads, 1 return pump controller and now 1 ATK unit. Frustrating!


Ran the Diagnostic test that neptune support sent me. I have to send it in since it seems to have a hardware issue.

Oh hey, what test did they have you do?

I've had a hell of a time trying to get my apex controller ATK to run properly.

In doing so i've already had to replace the PMUP and purchase a solenoid.

I finally got it working for a few days and I was ecstatic.
But the other day I came home again, to what you are seeing.
Water topped off all the way up until the float stops it.

Fwiw, after that day where it did fill until the float valve shut it off, it has been working fine. I didn't touch it either. But I've been checking every day and waterline is at the first sensor!

Previous to this i used tunze for several years. It lasted about 6years. Needing to replace the pump 2 or 3 times.

Before that I used a simple gravity fed top off with float valve.

I went with the atk thinking the optical sensors would be great, i had them fail while on the road, bought replacements.. had them fail.. then finally when laid off had time to contact neptune support. the internal webpages never updated properly when i first installed the unit and failed optical sensors. they sent me 4 new ones, 2 new ones on my ato, and the 2 old but working ones into my resivoir.. 2-3 months later in the last week or so... both of the ones in the resivoir are failing and i think the one im using for high water is stuck in my ato. when i get some spare funds its time to go back to mechanical floats i guess, right now its a good thing im not working as i can manually fix my top off system. neptune support was excelent to deal with, I guess it might be time to open another ticket.


I still have my origonal jbj unit, its second set of floats are done, i got the atk so i could "SEE" that its working when i am on the road.. instead i could just see that its not working.

I got the ATK for the optical sensors as well. Although in my case, it's the fmm module itself that died. Still annoying to have to wait a week plus for the new one to come.
