My pool and equipment are fully winterized . During the summer I had to add Muriatic acid every day to my new plaster pool when we kept the temperature in the high 80’s. Now that the temp is in the low 40’s, I add acid every 4 days which is a piece of cake considering what I am use to...

The reason for this question is that every 4 days my pH goes up to ~8.5 (8.7 if I let it go 5 days) and I adjust it back down to 8.0 with 1 cup of muriatic acid. I asked the questions with the numbers I provided because I am considering adjusting closer to those numbers as the temperature...

Happy to comply

I have an Apera700 pH meter with built in temperature compensation, which is good to 2 decimal places. I use 3-point calibration with buffers 4, 7, and 10 to calibrate it regularly. I also use a standard of pH 6.86 to verify it is reading accurately after each reading. I also store the...

Specifically, in the winter time when no one is swimming, is 8.7 ph going to be a problem in a plaster pool less than a year old if csi is zero? Cl 6ppm Ph 8.7 TA 50ppm Calcium 250ppm Cya 60ppm Water temperature 35F Salt 3200ppm

I feel your pain. I am going through a very similar thought process right now. If your curious my Thread is called. 'Postponing Closing/Winterizing to the absolute last moment". I actually have a ton of time on my hands, so I don't mind opening up my straps and dropping pumps in to...

If i close in September like my neighbors do, and open in May….that would be around 8 months …that amount of time with constant rising pH could make CSI wayyyyy out of wack. You are correct, it is only temporarily high because I have been opening the cover every 4 or 5 days finding the pH as...

Did not know that…. I guess if I would have closed like my neighbors in September, it would be closed at least 6 months . I am curious though…why would high csi be less of an issue if the pool is closed?

Well, it didn’t take long. The day before Thanksgiving I took a sample from the closed pool to test and the PH was 8.47! And I was in the scale forming area of the CSI. I panicked and overnighted a submersible pump from Amazon- capable of 5722 gallons per hour and I dropped it in the pool...

That’s a good option worth considering. I was thinking of using the existing drain lever on the multicyclone prefilter which has a 1” opening. Instead of attaching 125ft of 1/2 inch garden hose like I did, i can use a 1 or 1.5 inch drain hose (like the one in your amazon link) the entire...

I started draining down my pool yesterday using the spigot right above the vsp and ~100 feet of hose to take it away from the house. That setup took 43 seconds for the water to fill a 5 gallon bucket…. So that would have taken 8 hours to drain my required gallons. I realized having the one...

Well closing day finally arrived today…..The temp was in the mid 50’s, my pH maxed out yesterday at 8.34, and next week is forecasted to have 6 out of 7 nights below freezing and most days in the low to mid 40’s. I don’t want to push it out any longer. With all the sun the past couple of...

My cover requires no lower than 18 inches from the top of the coping. 16 inches below the top of the coping gets me 4 inches under the returns and 6 inches under the skimmers and 8 inches above the underwater light fixture. Not much wiggle room….

I actually prefer the water maintains it coldness. I'm not looking forward to closing in the cold . If I run out of 50+ degree days (as forecasted) , before I can find a resolution, then I will table all experiments and close. I have everything ready to go including cyclone blower, solid...

We have had the several low 30's and upper 20's here as well, but.........However, It was 65 today in central NJ and going up to 68F tomorrow. I'm trying to stretch it out to see if I can get my pH to stop rising. Since my water is 43F I am not concerned with sanitation to much (my chlorine has...

got it

I don’t have a set time. I will decide based on water temperature and 10 day forecasts. As of now, the next 10 days do not have multiple days in a row where the temperature does not rise above 50F during the day. And, as long as 40 to 50F degree water is flowing through my pipes I can’t see...

When I do close , i will drain below the returns so I won’t have to stick my hand in the thirty something degree water I expect to close at. 😉

I have read that if pH rises above 8.0, that you need to add acid to bring it back down . However, according to the CSI, it indicates that pH can be allowed to go as high as 9 or more depending on the levels of your chemicals. I am currently battling rising pH and am trying to get a better...

I had my alkalinity at 50 for close to a month and my pH continued to rise like clockwork. So I raised in to 70 for the approaching winter and my plan to follow CSI/LSI levels. Currently the pool needs 1/2 cup acid daily to keep it below 8. If I skip a day i need to add a full cup. My current...

Another reason I want to wait is because every single day, I have to add muriatic acid to keep my PH from going up in my new plaster pool to high…. And that’s much easier with the pump running to mix the acid in…. I am concerned if I stop to far in advance of the water freezing the PH will rise...

I also should mention I run my variable speed pump 24/7...1400 rpm during the day and 2400 rpm at night when there are freezing or close to freezing temperatures.

My first season of being a pool owner is wrapping up. As of today 11/3/23 my newly built inground gunite pool is still open in central New Jersey. The outdoor temperature dropped to ~27F for a few hours overnight during the past 2 nights but rises back up into the 50's during the day. My pool...

Looks like you went with the low bidder as you mentioned the range was 60-130k. I too went with the low bidder earlier this year in New Jersey and my bid started at 65k for a 30x16 gunite simple rectangle inground pool 3.5' -5' deep no spa...and I ended up paying close to twice that cost once...

Looks great. What was your final out the door cost if you don't mind sharing?

We have a gunite pool under construction that will be 30' x 15' with a deep end of only 5 feet. We are starting to 2nd guess our finish color selection of Quartzscapes Sky Blue. Since at this point it likely won't be installed until spring of 2023, I suspect it should not be an issue to change...

Hello all, I just found this site while researching pools. Currently just completed the Tile and Coping stage of a gunite in-ground pool. Concrete decking is scheduled for the end of the week. Details are as follows: 30' x 16' pool, 3.5' deep in shallow end and 5' deep in the deep end...
