Well last 3 hours my ph has been glued to 6.61 so far. Which is where I want it. But we'll see as the ph rises because of lights /photoperiod. But if it hangs in during peak lighting I'm good

Btw the my ph in reactor dropped .05 during night. So it went from 6.82 to 6.77. with my reactor set at 6.60 with .05 up and down. Dropping .05 will still keep my co2 on. So in theory should rarely turn off

What I’m finding annoying right now is that I keep getting Apex alarms.
Based on the programming I’m using the reactor will keep chugging along until my alkalinity gets to 9. Then the solenoid shuts off and the reactor is “off”. Then the pH in the chamber rises. No big deal except I have alarms to tell me when the pH is out of range. My alk hit 9 and now I get high pH alarms every hour. I should really ask about this on the Neptune forum.

What do you mean your reactor shuts off? Do you mean the pump that controls effluent? Hopefully you're keeping the recirculation pump running.

Why don't you program the Co2 solenoid to shut off when alk hits 9 as well?

IF ALK > 9.0 Then OFF

That would solve the issue however it seems like you need to fine tune you CaRx, if your hitting your max alk limit then you can either slow down your effluent, raise your pH settings in the reactor, decrease the bubble count, or lower the regulator pressure. Perhaps a combination of some of those would work better.

Once you get the reactor dialed in you shouldn't be hitting that peak number very often if at all.

The pump still runs and drips effluent. The solenoid just shuts off.
I can adjust the pump quite well but the CO2 is very hard the control. I’m at about 1 bubble per second. I need one of those Carbondoser things. So expensive.
I have a lot of adjusting to do.
I shut off the alarms in the meantime.

I don't use apex but sounds like your co2 is to high. Slow it down a little. If alk is rising. It's to much. I have mine dialed where it's 6.6 to 6.61. Doesn't budge. So solenoid stays on 24/7

I stopped using that Apex program. It’s set to keep the solenoid on for 15 off for 5 on off on off ... I totally didn’t understand the point so I went back to regular +/- 0.05 pH with a max out at 9.00 dkh. It’s stuck at a pH of 6.85 which is fine as long as it’s consistent. I am decreasing the flow ever so slowly (-2 mL/min) until I get to a better dissolving range (~6.5 to 6.6) but if I get the alk consistently at 9 with a pH of 6.8 I’ll stay with it.
Before the Kamoer I used to drip the old CR based on how many drops I felt looked good for that day and the corals grew great. I feel like I’m overthinking it now.

My solenoid hasn't turned off once in 7 days. It's doable

If you want I'll me more than willing to help u over course of a few days dial it in so your solenoid isn't on off on off and or your outlet burn out

No it was the program that turned it on and off. Right now it stays exactly at pH 6.85 and the alkalinity fluctuates between 8.85 and 8.95. (The solenoid shuts off at 6.45 but I don’t get this low). This isn’t what I planned but it’s working.
Ideally I want to bring the flow down and decrease the pH but I’ll attempt that once I have a Carbondoser. Then I can dial it in precisely.

1dkh fluctuation. Odd. Especially when it stays at 6.85. Is this auto tester or manual

Oh I missed read. Thought it was 8.85 to 9.85. Im a dummy

So from what I understand if I set my kh director to control my carx. It would make small ph adjustments I'm not sure how that works without the ability to turn the co2 up manually. I think it would lower the bottom line ph to turn off at a slightly lower ph. That being said if mine never gets to the bottom and runs at 6.60-6.61 and my bottom line is 6.55. I'm not sure how is use that

I’ve heard that solenoids are not meant to be constantly ON because they burn out. Maybe an electrician can explain if this is true. So now I’ve gone back to the old programming I used with the periodically forced ON/OFF. It maintains the alk and pH by allowing small amounts of CO2 into the chamber over time rather than all at once. It’s been working really well now that I understand it haha.
The Trident or KHD just sets a max where it turns off and a min where it can stay on. I guess kind of like safety features.
Anyway it’s just for discussion. I like to hear how others do things and why.

I've read they are not meant to be on/off/on/off. Lol. I'm interested now
