Don't retest CYA until it's bright and sunny out. You have a pool volume similar to mine. It takes mine at least an hour to fully circulate, sometimes longer.
TA is the last thing you worry about. It will come down naturally as you lower pH.Ah...didn't know that about the liquid stabilizer...good to know it ends up costing more....
Retested just now and here are my readings:
TC: .04
FC: 4.6
pH: 7.8
TA: 140
CH: 270
CYA: 37
I added a little more acid per the poolcalc to bring down the pH, but it is telling me to bring my pH down to 7.0 and aerate to bring it back up to get the TA down. Should I do this now, or try and get my pH down to 7.5 first?
I am assuming that (since it is dark) I should not see a big decrease in my FC overnight, am I thinking about this correctly? Or since this is a refill, will it bounce around before it stabilizes?
Right now, I have just added the additional acid to bring the Ph down, I have not added any more stabilizer or bleach. I am running my pump (new sand) continuously as well as my robotic pool cleaner.
The water is a little bit cloudy. Before adding the chemicals, it was crystal clear (from the tap), as soon as I turned on the filter and added the chemicals it turned cloudy. Not too much, can still see the deep end drain in 8' of water, but nothing like it was before adding chemicals.
I plan on continuing to run the pump and the cleaner 24/7 for right now until I get everything stabilized. I am trying to get this done before we leave for our cabin for Thanksgiving. We will be gone Mon-Fri, so next is to determine what levels I should have before we leave! Any suggestions would be great.
Thanks

I put mine in two socks at a time and walked around in the pool with the music on and squeezed until it was gone. Did again it was gone! Hey TFP said to put ?? CYA in and it was going in right now! LOL Too cheap to pay for the liquid though.

According to Effects of Adding Chemicals at the bottom of poolmath, every 8 oz puck will raise your pool 1 ppm CYA. So you can safely use as many as 30 pucks --15 lbs. Pack as many pucks as will fit in your floater in there and open the thing up wide. You don't need to worry about overstabilizing things.<snip>
We are leaving for about seven days tomorrow and with the CYA at 37 it has been suggested here that I could put tabs in a floater to keep the FC up while we are gone. I guess my question there is how many tabs do I use to keep my FC up where it needs to be if we are going to be gone a week?
We are converting (next week) to the AutoPilot SWG system and I have read here that my CYA with an SWG needs to be around 70 to 80, so I don't think tabs will be a problem for a week, just don't know how many to even shoot for right now.
Thanks!

By TC, do you mean CC? With a CYA of 40, your current FC is borderline. You want to target at 5 or so. How many tabs fit in your floater?
I can just picture Teacher Ms. Kim dancing around the pool to music. What was the song?--- "the wheels on the bus go round and round"
The "concentrated" 121 oz bottles are usually 8.25%
I am going to aerate tonight which is supposed to raise my pH back up (as well as lower TA). I will report back in the morning.
Regarding TA, I read your previous post -
That's not quite right. Adding acid is what lowers your TA (and pH). It lowers TA by converting the bicarbonate (HCO3-) alkalinity in your water to aqueous CO2. Then, the process of aeration increases the outgassing of the excess CO2 which also raises the pH back up again. So, you add acid, which lowers the pH and TA, and then you aerate to restore the pH to normal levels without creating any additional TA. Keep doing that cycle enough and your TA lowers.
So, the only time you will measure a decrease in TA is when you add acid to the water.
