I did do that all day yesterday. Today is the first time I tested it where the FC was in the normal range of 4-5. It held close to shock level overnight which is what pool school says is one of the signs that you can stop shocking if I understand it right. CC is 0...FC held close to 1 overnight...

I had to use a test strip for CYA because I ran out of the regular test. Probably a bad reading then because all I used was Baking soda, bleach and the soda ash since I had the 50 reading to start the process.

Update...Pool held the chlorine pretty well last night. Chlorine levels only fell a couple points. I had to leave this morning and just got back and tested the water. The Chlorine is still holding under the hot sun at normal ratings (FC and TC around 4). PH and TA holding at 7.2/90. I did notice...

Went back over it again...CYA/FC chart show shock value of 20 for 50 and 16 for 40. If I go on the high end and say 20 then I put that figure into the pool calculator FC box and calculated at 12,000 gallons. That actually gave me 498 oz so I added another bottle of bleach whic equals 492oz in...

Noticed calculations were wrong. If I need to bring FC to 15 to shock it then with 50 CYA readings I need to go to 373 oz of bleach so that would be 2 full bottles. I am putting the bleach in now...TA to 90 and PH right at 7.2

Thanks for the help...So for shocking...If shock value is 20 and 1 bottle of chlorine gets me there then I dump the bottle in every couple hours until the sun goes down and this should hold it at shock level. Then I test the water and let it sit over night and test in the morning to see where it...

Might be stupid question but can I put the BS and Borax in at the same time? Do I need to hold off on using the bleach until PH and TA levels are in range?

So according to the pool calculator I should do the following in this order Raise PH by adding 33oz of Soda Ash (Or 66oz of Borax). Raise alkalinity by adding 56oz of baking soda Shock pool by dumping in a full bottle (128oz) of bleach at 6% (Standard bleach from grocery store) From what I...

My fill water PH is around 7.5 and CH is pretty high out here in AZ (400-450). Looks like I have added to that a bit with the Cal Hypo but maybe that isn't as big of an issue out here since it is high to beging with. I would rather not drain the pool if I can live with it for now. If not for...

I bought a house with a pool in AZ when I moved here 1 year ago. The pool was emptied/cleaned/refilled at that time. The water has had near perfect readings until about a month ago when I started seeing black/green staining on the pool walls. It didn't look like Algae spots, but more like a...
