LF Opinions on ATO Units

Well it’s been just under a year and a half and my Neptune ATK V1 is pooched. Constant alarm and refusing to fill the return section. As of right now I’m using only the pump and plug go my in to top up morning and night. So pretty much filling up manually. Of course 1 year has is over so no warranty. I’m pretty disappointed as the cost do the Neptune ATK was pretty high for the overall value of the product.

Moving forward, I’m looking to replace the ATK with another ATO device capable of maintaining top up on my 300g system. Let me know what’s good, what is reliable and worth the money. I do not want have to dump $200 every year...

I have had my tunze ATO for 4 years and not had a problem, knock on wood, I have a spare pump just in case.

I’m kicking myself as I was going to go with the Tunze but jumped on the Neptune wagon... sigh. If I’m putting that money out again I think it will be the Tunze, don’t need anything fancy and my primary goal is reliability.

I've used the JBJ for 7 years now, you can add whatever pump you want to the system and I did change the pump once, and just last week one of the float switches packed it in but a 7 year run I would say is pretty good in this business

Cheap too

I had trouble with my ATK as well. Worked fine for 6 months then would constantly fill. The problem was the high and low sensors were in the wrong spots. I have the steps they use for troubleshooting errors. Let me know if you would be interested in it.

I am using the Tunze osmolator 3155 right now. Only been using it for a couple weeks, but it seems to work well so far. It is much quieter than the ATK when pumping water I have found.

Are you up for DIY job?

A couple float switches can be found on ali express and wired into a Neptune Breakout box (you can DIY that too!) along with a 24 volt solenoid (again, aliexpress) tied into the 24v port of the Apex for a rock solid ATO. I'm doing the exact thing - total cost in was $22 including building the breakout box. External links not allowed here but if you PM me I can send you a parts list.
