Heya all!

It has been a week since my newbie self set our pool up. It has been crystal clear so far….yay!

I have been testing a lot…twice a day…trying to get used to it all. I suspected I will have a few ‘user errors’ testing while getting aquainted with it all. I am guessing I will need to order more test refills due to all my testing to learn lol. How low should I go before reordering because I do not want to be out & blind?

My TA has been high the entire time (but just read that could be due to static & to wipe with damp cloth so will do that next test). pH has not gone up crazy (but has only been a week) & I am planning to lower it at pH 8 to help control TA (read that as long as pH not crazy, FC & CC pretty stable …do not worry so much about TA). I have added a gallon of Muriatic Acid so far & lowered TA a little.

My main concerns were raising my CYA (which I have done) & trying to make sure my FC in range. I have been running pump (sand filter) for 8 hrs & SWG for 7 hours twice a day with breaks between. Yesterday, I ran my SWG & pump less to see if I could maintain because I do not want to overwork them & my FC dropped from 6.5 to 3.5. I am guessing I need to run them like I was since that kept FC stable.

I ran pump & SWG and it brought it back up to 4.5 and conducted an OCLT and it seemed alright (not algae etc eating it up) since my FC this morning 4.0 & CC still at 0.5. Just want to make sure I am doing the right things, interpreting them right & maintaining them right before I run into trouble. I have a tendency to overthink things lol.

I am surprised it is doing so well considering my TA so high but have not been freaking out about it watching my pH. I read about the static on the tips & will wipe with damp cloth next test to see if makes a difference.

My questions: Should I add my liquid chlorine to bring it back up to 6ppm or let my SWG do it by running it more often like I was (7 hrs at twice a day)? And how much Muriatic acid do you think I will need if static not the problem since I have been ordering online & would be nice to have it on hand instead of let it go for days waiting for order to arrive? Or do not sweat it & ordering a gallon a week is all good? Also I would like to order a variable speed pump for next year…what would you recommend for an AGP of 7000 gallons that has plug for outlet? And am I overworking them all & need a new SWG that will keep up with the VS pump? I also plan to upgrade to 16” sand filter. Overkill or will my stuff last running twice a day at pump for 8 hrs & SWG (I got the 15,000 gal to process twice as much for my 6981 gal pool) at 7 hrs?

These were my last results using 2006C test & the saltwater test as extra & have the smart stir (not counting the OCLT test) on 6/26 11:50pm

FC 4.5 ppm
CC 0.5 ppm
pH 7.8
TA 300 ppm
CH 150 ppm
CYA 80 ppm
Saltwater 2600 ppm

The OCLT test at 5:30 am
FC 4.0 ppm
CC 0.5 ppm
 
Good morning, sounds like what you were doing was working well for you... probably sticking with that routine would serve you well. Getting FC back into the 6 range for your pool with CYA of 80 would make sense. Adding a bit of liquid chlorine to help get it there quickly is probably a good idea then the SWCG will maintain from there. The pool math app is great if you don't have it. That has a section called Effects of Adding. It will tell you how much of what you need to add to make a change. So, once you verify your TA number, you can calculate from there how much MA you need to add to bring it into the proper range. Your TA number right now sounds quite high so I'd verify that number and most likely bring it down in steps while watching the affect it has on PH. Highly recommend VS pumps. They are great and save a lot of energy. I have a Pentair VS pump and I'm happy with it.

Thank you for the reply! And your pool looks lovely!

I boosted the FC up. Added 1 quart liquid chlorine night before (it is 10% but calculated as 6% because was over 3 mo old) and did not really move anything when I tested at 5:30pm. We had some rain in the morning & pump/SWG had been off. Turned everything back on & added another quart of liquid chlorine let it run a few hours. Later added 1/2 gallon Acid Blue muriatic acid. Just tested again and my FC jumped up & my TA finally dropped some. Yay! Will see how it looks tomorrow when I test again.
 
Test results from today at 3pm

FC 7.5
CC 0.5
pH 7.6
TA 275
CH 225
CYA 80
Saltwater 2600

I am going to test again later because we had lost water & was starting to go below return nozzle. Added about 460 gallons of water after I did that test.

And the water temp was 83.3 F if that matters
