Interesting call out. I didn't actually realize there was a signifcant difference between CSI and LSI and I like the Orenda calculator for LSI vs the Pool Math calculator for CSI because its a lot easier to see 'what if' scenarios, but since discussion here tends to use CSI I'm going to switch...

I've done a bit of reading since last night. I'm not a chemist, high school chemistry was as far as I went, so I can't proof your computations but with all the reading I've been doing I'm convinced that your explanation is solid and that there is a fair amount of misinformation out there...

Good things to consider. Here in south Florida I think rain water would be more the consideration than tap water. I haven't added a drop of tap water all summer. I would imagine the rain water is fairly low TA as well but the major factor seems to be the regular addition of acid.

James, I see PH meters range from under $100 to up close to $500. Obviously I'd prefer the lower end of the range but don't want junk thats going to cause me more problems. Do you have a recommendation ?

I'll start by saying I'm reconsidering everything at this point based on the feedback received above and the change in season. During the 'swim' season, which for me ended this week since I don't have a heater, with water temps from 80-88 I like to keep the PH around 7.7/7.8, Stabilizer...

No particular objection, other than it sounds expensive, I thought it was used more commercially but I'm going to do some research on it. Anyone here using this type of system for residential pool ?

We can agree to disagree on that, its not really relevant to the thread.

Not really relevant to this thread whether CO2 outgassing lowers TA but I have provided some sources that back up the claim. If we stick solely with the reasons you posted we can still agree that the TA is going to drop and I'm back to the original reason for my post, looking for a way to keep...

"When the water evaporates in the pool, it is not only pure water (the H2O molecule) that is released, but also dissolved CO2. This is what is called the water degassing phenomenon. The removal of this dissolved CO2 from the water will have a direct impact on the total alkalinity, and will...

Nevermind, I misunderstood you. Yes, the acid and the aeration will cause the TA to drift down, I agree, this is the reason I am looking to add back baking soda on a dosing schedule as I have done with the acid to keep it closer to in check on a daily basis and then just make small adjustments...

I'm not lowering the PH, its holding rock steady at 7.7

Yes, thank you for catching that typo, I want to increase TA not reduce. Not sure what you mean which TA ? I haven't figured out the 'schedule' of the TA drift as I have with the ph quite yet, It seems to be somewhere around 10-20ppm per week but that's just a guess at this point.

Joyful, The acid through the dosing amounts to about a cup per day, and it maintains at 7.7/7.8 which is not significant enough to cause the TA to drop. The TA is most likely dropping as a result of the aeration not of the acid. The aeration source is the multi-level waterfall. The...

Thanks Jeff, I mean Dura, I needed a laugh today, I found the humor in it, don't worry. I'm not a chemist but I did mention that the acid is diluted 2:1 so I don't quite think it would be quite as volatile as y'all are envisioning but open to ideas.

I am already familiar with how to manage my pools ph and TA. As I mentioned above, the pool is in good balance, my ph and TA drift due to the aeration from the waterfall running all the time plus the effect on ph from the SWCG. I am looking for a way to manage it proactively on a daily basis...

I've got all my chems and my LSI balanced pretty much right where I want them. I have a large waterfall that I run all day and an SWCG so my PH drifts up and my TA drifts down. I installed a Stenner pump a short while back and have the mixture (2:1 water/acid) and the run time pretty much down...

OK, scratch my original theory. I went out to my pump and pulled the power and ground and it works fine. New theory is that of the two data wires, one is transmit (data -) and one is receive (data +). My guess is that possibly your receive wire is working and your transmit wire is not, those...

Also, its not necessarily wrong to power the pump from Relay1 instead of the breaker directly but the wires should be connected to the hot side of Relay1 where the breaker power connects, not to the 'controlled' connectors. I don't believe code permits multiple wires to the same breaker unless...

I connected my new IntelliFlo3 to my ET and used all 4 wires. I didn't try it with just the two so I can't say that it does or does not work that way but I can tell you that it absolutely works with all 4 pins connected. The other two pins are ground and power which you wouldn't think would be...

The WiFi on the Intelliflo3 continues to work even if the pump is hooked to automation. It continues to report status, errors etc. to the Pentair Home app (cloud) even though you can't actually control the pump with respect to programs/speed etc. I received a few emails yesterday that stated...

Hey Jim, For this pump there are three buttons on top, you can probably just make them out in the pictures, so I attached a new pic. They are "connect" "On/Stop" and "Quick Clean" They have different colors to indicate different states and the connect button changes to magenta when its...

Finally an opportunity for a little bit of give back on this forum. With some support and encouragement from my friend @Jimrahbe I purchased this new Intelliflo3 VSF pump mostly because the previous model was infinitely backordered. I am so glad I did, so far I love this pump! Here is my...

@wireform Any thoughts ?

Thanks Jim. I'm gonna go for it. I'll have it installed in the next few weeks and post some feedback. It seems even the vendors aren't that familiar with it yet, but as best I can tell, both the 011075 & 76 support bluetooth and wifi out of the box for configuration without the top...
