Dosing: Controlled via Apex vs Standalone Units

[Velodog2]

There would be need to control it from the apex unless you want a failsafe backup if the ph gets too high. The jebao unit has a built-in controller.

Use Apex to kill power to doser if pH gets wrong.

That's what I do! Unfortunately when I had the dosing pumps hooked to the Apex it said the outlet was off when it was really on. I cycled it ON to OFF remotely and it never turned the pump off. My wife had to unplug the dosing pump.

Of course this all happened while I was traveling for work!

So let me get this straight - the dosing pump controller stuck on AND the Apex unit stuck on?

Sorry. At first I was running 3 separate BRS dosing pumps via the Apex. My ALK dosing pump stuck in the ON position. I commanded it off remotely and it said it was off but the pump was still turning. It had to be unplugged and the EB8 had to be reset. I think the issue is that they draw too little of power for the EB8 to sense, so it never really knows if it's on or off. I've read that hooking a light bulb or some other form of resistance will help it to decipher when it's on or off.

I now run a separate, standalone dosing station that is hooked to the Apex. If my pH gets too high it will cut power to the dosing station. Which is good and bad because with no power the CAL and MAG won't dose then but at least, hopefully, the ALK won't spike too bad.

For those of you considering using the new Jebao DC-4 dosing pump I thought should share this post copied from another R2R thread... (not sure if its legit, but it was enough to make me reconsider better options!)

... Hmm strangely I can not copy and paste the link for some reason?

Put this into the search box: "Jebao auto dosing pump dp-4" and then see post #22

On a side note, I have a brand new unopened DP-4 available for purchase! :crossedlips:

The guy still don't know what happened for all we know he might of mistakenly set up one of the settings
