LOL, but what I noticed is surprising. You would think a probe would be responsive. Neither one is totally accurate, though the GHL is closer, but to actually respond to adding salt to a 100 gal mixing tank, you would think they would respond. They do respond, BUT, one takes a few days to do so...HMMM!!!
I mix it in a 5 gal bucket to dilute before adding it the 100g container. I do this a few times to raise the salinity. Both the GHL and Apex probe are mounted next to each other. My ATO 100g container is separate. I have a 200g mixing station, one is for RO/DI and the other is for mixing.
As of right now, I have a GHL P4, KHD, 3 6E powerbars, 2 stand alone dosers/ 1 is tied to the KHD, 1 expansion box on my mixing station, and several cards added to the P4 and expansion box. I still need to order a part to add my Abyzz A200 to my GHL to control it with the GHL. I am waiting on the IOND. I just haven't had time to post it, but, I noticed a big difference in the salinity probe, especially on my mixing station. The Apex probe does some funny things. When I get time, I will post my findings on the salinity probe. Connectivity of the P4 can be a little suspect at times, but, I never had any issue on my phone, and that is what I use any controller for, to monitor and address any issues while I am not home. I do feel the GHL probes are more stable. I don't calibrate probes as often as I should, but, I really don't use the probes except to see a trend in one way or the other. I still use a refractometer and temp probe to check periodically. I usually only calibrate probes when I am doing a comparison between the Apex and GHL so I don't have to here it down the road. In truth, I like the GHL better than the Apex overall. After getting use to the interface, I actually like it better than fusion because it doesn't have all the flash, it simply has what you need. Also, with Apex telling me to send in 3 EB832 energy bars because they could not find out what was wrong with the current sensors and such after I recalibrated them and then they dialed into my computer and did the same, YEA!!! Its about the build quality to me, and I feel GHL is ahead on the parts quality used to build the equipment.
Sorry I didn't see this sooner. Have you updated the firmware yet?Thats great utility. I should try to figure this error out before jumping into the full controller system. Makes sense to make adjustments on the fly, away from home, when the IOND is telling you the alk is off, for example. I will be away from the tank often. I've hardwired the doser to the pc several times and checked updates and tried power cycling it as well as reconnect to wifi. Still no dice. It used to work from my phone until one day this is the only message I get on mobile app for android. Always wondered if the apple version is better, too. I'd change phones if the app was flawless on iOS.
Surprising, as I also use a android and don't have any issues. I use a Samsung Galaxy S20+.
I will give the opposite opinion to Bill, I find my Profilux miserable to use versus Apex. It’s very subjective, some people are fine with it, I hate it.
You have multiple connectivity options to choose from, GHL Control Center (Windows) is just one of them.
