Baqua to Chlorine conversion with cya of 40.

I guess the other alternative would be to float some trichlor plucks and let the cya build gradually until I get it where I want it.

You can, as long as you keep the FC within target range for the CYA level. Can be difficult using pucks only. As you see right now, your FC is disappearing pretty quickly during the day.

I suggest you simply use granular CYA, enough to get you to 30-40ppm, using however many socks it takes hanging in front of the return or sitting in the skimmer. Squeeze them every hour or so and then just assume you have 40ppm in the water and start dosing chlorine. These’s no need to turn this into an chemical engineering experiment … get the CYA in and go.

Yes! :goodjob: Once I know how much stabilizer to add, I fill a sock and let it soak in the pool somewhere for about 30 minutes. Either hanging from a stick near a return (not resting against the wall) or I set it in the skimmer basket. After 30 minutes, I squeeze the sock continuously for about 5-10 minutes and it's all out - done.

Here is where I stand this evening. Ignore the CYA as that is just the current goal as it is currently dissolving.

PH was very yellow, so I just guessed at the number since it was below what the chart measures. TA is low.

Chlorine oxidation reactions can be very acidic and you used a lot of chlorine to destroy the baquacil.

I suggest you add baking soda to your pool to get the TA up to at least the 60-80ppm range and the pH should rise on its own especially if you give the pool a good brushing.

How did you get a TA of 33?

I added 2 drops of r-007, then 5 drops of r-008, and it only took 3 drops of r-009 for it to turn red.

I used the smart stir the whole time.

*EDIT - I just realized it says to multiply by 10, I multiplied by 11....lol. (I guess because the example in the instructions says 11 drops)

Pool math says I need 8 pounds of baking soda. Is this just regular baking soda from the grocery store? Does it need to go in a sock in the skimmer, or just distribute it directly into the pool?

I really appreciate you guys helping me out so much!
 
I found 2 tubs of this in my shed. Each tub containes 4 lbs. Both tubs are sealed. Baking soda is sodium bicarbonate, this is sodium carbonate. Will this work to increase the alkalinity? I have no idea how old it is or if it has a shelf life. If you say to not use it, it's going in the trash.

It will very strongly raise pH and TA. You can use it, just in much lower amounts. Use PoolMath to figure out how much. I would not use more than enough to raise the TA by 10ppm or else you can severely spike the pH and cause cloudiness

Washing soda can cause prolonged cloudiness.

Some people have no problems with it, but I would never use it.

I think with his low pH/TA/CH it should be fine. If it’s added slowly and brushed/mixed really well, I bet it will not get cloudy.
