apex atk

Sorry for the frustration but I can't figure out what's wrong with this thing. I have tried everything I can think of.. The ATK will work but a few days after it will come back with "Error on ATK" and the water line drops. It's almost like the pump can't keep up with the evaporation but I can't...

Hey all... New to the reefing world. I wanted to post a brief intro, some photos of my setup, along with a question... I started my build in October and took it pretty slowly this has allowed me to tweak things and get them (mostly) just how I want them before adding livestock. I decided on...

I’m setting up a new tank and my mixing station is 40 ft away on the same level. For ATO, I was thinking to use the neptune ATK module. I understand the DC24 extension cable can be used when the pump is far away from the FFM module at the sump. I also read, instead of the DC24 cable you can...

I’m setting up a new tank (RS S1000 G2) and my mixing station is 40 ft away on the same level. For ATO, I was thinking to use ATK module. I already ran 3 color tubing and an Apex USB cable. But I didn’t run the DC24 extension cable. Which I now see is important to extend the ATK pump for...

ATO and Sky light problem Bought 2 complete apex systems one for my 120gallon tank and the other for my 50gallon tank. The probes for both are inaccurate always (fact check them with commercial water test equipment); ATO on both don’t work even though the status light on the FMM shows green...

Hello all, and thanks for stopping in to read and help if possible. Just installed my first apex and I have most of it figured out, but The Kalk stirrer and solenoid valve programming is starting to scare me. I had to run my top off line through a couple of walls, so adding a second line and...

Edit: Problem just solved. My FMM was accidentally switched off. ATK has been up and running pretty good about 3 months. A few times, I’ve found the PMUP switches from auto (where I have it set) to off. What causes the Apex to move this? In the past, I just switch it back to auto and the...

Something odd happened yesterday and I am wondering if someone might be able to provide some insight. I will try to make it short and concise. I have a VarioS-8 DC pump that has been running for two years. The pump has been using around 74 watts per what Neptune Apex is showing. Yesterday for...

Hi fellow reefers. I have a situation that I would like confirmation that my logic is correct. I have the Neptune ATK (with 2 sensors) in my return pump area of my sump. It’s configured to run once an hour. I have Chaeto in my sump. It’s grown using the Kessil H380 from 10pm to 10am PST...
