Neptune auto top off failing
 

My neptune auto top off seems to be broken or is now failing.

It is standalone, had it for about 6 months with no issues.

This morning I checked my sump and found the water level was low. Checked my controller cabinet and the ATK didn't have a warning light on so I unplugged it and plugged it back in which got it filling again, but now it won't stop. Hits the first sensor and keeps going, hits the second sensor and keeps going. I even manually lifted the float swift as far up as I could. LED is green and pump is still going.

I wiped off the sensors and wiped off the float switch. Doesn't appear to be anything on them.

is my auto top off broken or just needs a good water and vinegar soak and scrub?

on your fusion dashboard is it set to ON or AUTO?

I have it as standalone. Since I don't have the apex controller yet.

oops missed that part...mine has done this kind of thing before even hooked up to the apex,

usually unplugging everything and re plugging in works.

Tried that. It immediately starts filling and the only way to stop it is to unplug the power.

Even pulling up the float valve as far as it will go doesn't stop the pump.

The float valve is in place just to stop the water flow from the pump in this case where the optical sensors have failed.
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...

yea that's called reefing lol

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. :cry:
