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.

My Neptune ATK acted up one time, similar to where it refused to top up my sump causing my return pump to blow bubbles. I took the sensors off, repositioned and unplugged. When I put it back on it seemed to be working fine. I’m a littler nervous with this ATK now, i purchased the Neptune ATK (known brand) to avoid any hassles.

I’m hoping I don’t fall victim next to these issues.

PMUP on that unit is a lemon and frequently the cause of failure for an ATK. The sensors can also go bad, or the module itself. Not the best of Neptune releases, I'd say their most unreliable product which is ironic since people purchase it solely for reliability.

If they insist you return the product for RMA that's another $20 or so to ship it out, something to keep in mind.

Man glad i didn’t buy one, sorry to hear about your frustrations....

I am sorry to hear of your problems.

I think the most important feature of an Auto Top off is reliability. If you can't trust it where does that leave you, a disaster only a heart beat away.

Doesn't sound like the Neptune ATO fits those requirements based on the responses I am hearing from different reefers.

I stopped using my float value when I found it was unreliable and bit the bullet and purchased the best ATO available. Also building in a back up into your topoff is not a bad idea.

My back up is only having a day and a half worth of water in my topoff bucket. Even if it completely dumps all the water into the tank it will not throw out the salinity that much. Those reefers that hook the auto topoff directly up to their R/O system are tempting the gods.

They are shipping me a new one now. In a package with return postage. So I put down a $100 deposit which they hold until they get the broken unit back. Then I get the money back. As long as it isn't broken due to water or physical damage.

Ya I have had a few issues with this ATO unit. Luckly I have always caught it before anything bad happened.

What ATO did you buy?

I usually have about a 1-3 days worth of water in my reservoir. Unless I am going on vacation and will be away for any period of time.

I have a Tunze 3155 ATO that I have had for 3 years that I have been happy with.

Same here 6-1/2 years and counting. I replaced the pump once as it was getting noisy, but it was still pumping fine.
I added a high sump float to my RKE that will shut off the ATO in the event of a failure but so far so good.
