I’ve thought about letting my alkatronic handle bicarbonate, it has a built in doser for small corrections.Maybe we need to set up a third dosing pump with baking soda to smooth it out even more
I’m really curious to see how your system reacts switching to toggled dosing right off the bat. I wasn’t really impressed when I switched to all lye dosing initially. The pH definitely rose over the first week but the swings became huge and unpredictable. Toggled dosing has made a clear difference.I keep staring at my pH value. It’s down to 8.02 and the apex is going to switch to lye soon. I‘m excited to see how it goes tonight.
what’s your system volume and current dosing amount?
Definitely a notable change! I wouldn’t expect it to peak a whole lot higher than normal. It looks like your daily swing is pretty tight alreadySo far it looks like things are going well. You can see in the graph below that it took out the valley in the pH curve last night. I kept the change point low (it switches to lye at a pH of 8.00 or below) because I didn’t want to make big changes too quickly. I’ll see how it goes this weekend, when multiple people are in the house, because that’s when I typically suffer from very low pH, then I may try to slowly bump it up a little to raise the overall pH level.
I’m curious to see if the new peak this afternoon will be higher because it’s starting from a higher point this morning or if it will still peak at the normal level.
Just following along, sounds interesting. I have the alkatronic and Apex system. would this type of Lye dosing working similar with a CaRx or would one also need the Soda Ash only?
I’d imagine you would need CaCl to compliment the lye however soda ash would be unnecessary. Your calcium reactor acts as the cal/ alk additive when above a certain pH threshold. This method could be applied toward any system using a high pH impact additive vs low.Just following along, sounds interesting.

I think part of it has to do with how zoomed in some graphs are. I can manipulate the data and graph view so it looks like I want it to... just like covid scientistsOn a side note, I was looking at all the spikes in your graph as compared to mine and wondering what that was all about, but then I remembered that you said that you were dosing upstream of your pH probe. I managed to get my dosing lines and probes configured so that I’m dosing downstream of the probe. I think that’s why my graph is smoother.

I wouldn’t think your tank would be a candidate for bicarb unless you had swings breaking 8.4ish. I may start blending my additives after I’m sure I have it nailed down, maybe 2/3 lye with 1/3 soda ash for low pH and 2/3 soda ash with 1/3 bicarb for high pH. But then you have the issue of bicarbonate’s low solubility...
I think it also has lot to do with your logging frequency and how it lines up with your dosing. I think default is 10 or 15 minute intervals and I have mine set to 5 minutes.Actually, looking back at my graph, if I zoom in to a couple of days ago I can see little spikes. This was before I moved my dosing tubes so I was dosing soda ash upstream of my pH probe.
