My ph is low and it laughs at Borax

FC 1.5
PH 6.8
ALK 120
CAL 60
CYA 80

The pump had only been running for 1 hour before the rain started, so I'm wondering what will happen tomorrow after a good long pump run. I also didn't fill it up to where it should be due to our chance of rain over the next two days. It's maybe 2" over the skimmer...right where the pump runs fine and the skimmer doesn't make gurgling noises.

CAL was 60 for sure. I measured with my 10000% WHITE LED flashlight and I could full see the color change. I guess the sun's yellow tint didn't allow me to see that before.

CYA was done with the flashlight and inside and I think the lighting isn't right to read it effectively as you are supposed to do it in sunlight. So I hope that goes down after longer pump running, a touch more water, and a sunny outdoor reading. I'll not be a happy camper after dumping 10,000ish gallons of water to not see a change.

Anyways, I added nothing and turned the pump off for the night. Tomorrow, weather depending, I will run the pump for 3 hours at least. I will probably dump in 1 big jug of Walmart Bleach and my last 2 boxes of Borax. Then retest to see if my ALK change helped my pH ability. So unless anyone has further input that's what I'll do tomorrow if the rain cooperates.

You cannot test CYA that way--you'll get a false reading. ALL the tests are best done in daylight or sunlight and CYA has to be done in direct sun.

Meanwhile, you should go ahead and add your last two boxes of Borax. Remember: Most pool test kits cannot measure pH below 6.8. It could be 4.2 and would show as 6.8. Until you get it to 6.9, you won't know that you've reached that 6.8.

IF they are not swimming pool forums (and IMHO there are only 2 worthwhile ones) then those posts are not really going to help you with your pool, are they;)

Well, it's not the first time a hot headed Mod has threatened to ban me is it? ;)
Must be a New Jersey thing!:D

If you're going to have to dump water, I would do it before using all the Borax, since your fill water is probably higher ph than your pool water---that way you lower your CYA and raise the pH at the same time with much less stuff added....

Are yoo talkin' to me? I SAID are yoo talkin' to ME????

Tested just now after 3 hours of pump running. Not sure how much it rained, but the water level is now perfectly in the middle of the skimmer.

CYA 80

So I just dropped one jug of Walmart bleach in and one more box of Borax. It's distressing that the CYA didn't go lower, but I am so not going to drain the pool again unless I start having problems.

Overall the water is MUCH improved today. Very little cloudiness as I can finally see all the way to the bottom. It needs a good vacuuming to waste but otherwise I think it's open and awaiting the better weather.

You need to keep a minimum of 5 ppm chlorine in a pool with CYA of 80, otherwise you're going to be fighting algae all summer. Also, if you use the trichlor pucks again this year, it's going to continue to increase your CYA and lower your pH, so I strongly suggest you use cal-hypo or bleach this year. I purposely run my pool at a CYA of 80 because I have all-day Louisiana sun with no shade and constant high humidity, but even I wouldn't allow my pool to go higher than 90 because I'd rather spend the summer swimming in my pool than shocking it.

Aylad is right on the money. Listen to her! (particularly about NOT using any trichlor!)

Ditto!

Further, your CYA DID come down: trying to read it at night by flashlight gave you a false score much lower than it was. The light must have made the sample look less opaque than it was.

The CYA test is PARTICULARLY sensitive to you always doing it the same way.
