Hey, that seems very familiar! :ROFLMAO: https://www.troublefreepool.com/threads/26-intex-planning-install-upgrades-and-landscaping-thread.197134/post-1854028

Ah yes, good point. All the energy going into the pump motor not wasted as heat in the motor itself from inefficiencies will turn to heat in the water. I did think of one other scenario. A pump on an above ground pool should not need a priming cycle before running (on a daily basis, initial run...

Yeah I doubt the pump itself will wear out, but like you said the seals will. I'm not an expert here, but the way these pump seals work is they use a thin film of the fluid they are pumping (water) as the lubricating surface the spinning part of the seal and the fixed part of the seal. Running...

That's what I was thinking. Another example is your car. Small things like water pumps, thermostats, etc aren't often made by Ford, Toyota, Chevy, etc. Heck, engines and transmissions are not uncommonly purchased by one car company from another car company*! If they die under warranty, the...

Fair point, I was. Considering that constant current power supplies are so cheap these days, it seems almost unfathomable that someone wouldn't use one. However, a constant current power supply would allow regulating chlorine production without doing on/off cycles at full output. The %...

I don’t think so. Matt can correct me if I’m wrong, but the chlorine production is dependent only on current once you meet the minimum required voltage. But to drive current, you have ohms law. Lower conductivity water would require a higher voltage for the same current. So the lower the salt...

Is this also why batteries driven with high charge/discharge currents have shorter lifespans vs an identical battery driven at more modest charge/discharge currents?

Do you know exactly what types of products you've added? I ask only because some algae products add bromine, and bromine added to a chlorine pool makes it a bromine pool. The issue with this is that while CYA stabilizes chlorine and keeps it from breaking down as fast in the UV light from the...

Odd. Did you ever figure this out? I bought one and loved it. I didn't notice any abnormally low FC readings though.

As stated, the more you pay attention to your pool and learn it, the less time you have to spend on it. I was able to get to the point I'd add about every other day, and test FC about twice a week. I think on average I'd try to test FC about every other time I added chlorine, once I got to the...

So, chemistry is NOT my strong suit. Perhaps @JoyfulNoise can chime in here too, and/or move this over to The Deep End. No. HCl itself disassociates when added to water into H+ and Cl-. This addition of H+ is how the pH of the water is lowered when you add muriatic acid, aka hydrochloric acid...

Pretty sure chlorine gas will still raise TDS, cause you'd adding chlorine. The end result is chloride ions floating around. When you add chlorine gas, it reacts with water to create HOCl, the primary chlorine disinfectant: Cl2(g) + H2O --> HOCl + H+ + Cl- Some of the HOCl with dissociate (I...

I may be petty, but since I have a printer that can print up to 13x19 I'd print off a picture of my pool, go back to the store, slap it down on the counter and say: "My pool looks like this always. I never have an algae problem. I never shock. I only use liquid chlorine to properly manage my CYA...

I know it's not the answer you're looking for, but I considered paper logs for a bit. But once I got familiar with PoolMath, I realized I really didn't need paper logs. The app was so much more convenient and useful. If I wrote it down on paper, I'd still have to enter all the same info into the...

I had 12.5% chlorine, 32% muriatic acid (not stored together), some dry CYA, and...that's it. In nearly all cases, that's all you need for a TFP clear pool: Okay, for plaster pools and very soft fill water you may also need some calcium, but I had a vinyl pool which doesn't need any calcium...

Chlorox pH up is sodium carbonate, aka washing soda. It raises pH and TA. The effects are immediate once dissolved and mixed. Just measure your new TA and pH and adjust pH accordingly with PoolMath. There's no need to panic or rush to add something to counter this. How big of a bag was it? A 4...

No, it won't. A vinyl pool doesn't have a minimum CH requirement, and adding CH isn't going to make the water clear. Low CH is only of concern insomuch as it can lead to a negative CSI for plaster or stone pools (and some fiberglass gel coatings), but negative CSI is not an issue for a vinyl pool.

I'll let the others walk you though the SLAM. But as someone who overwintered an Intex two winters, near trees, successfully, I have a couple tips for you. These apply more or less in general, but with an uncovered pool, or mesh cover, much more so. Firstly: You cannot wait till the end of...

I assume you mean it says on the TA tab "To lower TA you reduce pH to 7.0-7.2 and then aerate to increase pH"? Firstly, note that like it says on effects of adding acid, pH is approximate cause it's assuming a TA around 100 or so. If you pull open the pH tab, the amount of acid to lower pH to a...
