It looks like you are still on average losing approx. 4ppm over a 3-4 hour period, so you have a little ways to go yet. Just keep bumping the FC up to 24ppm or slightly higher trying to prevent it from ever dropping below 24ppm, keep brushing and vacuuming, and hopefully within a couple days we can get all the stuff in there that's depleting your chlorine out of there. You guys are doing Great. Keep up the excellent job, and have a fun and safe Labor Day :)
 
Instead of bumping it up at 11 this morning, we put in the rest of the chlorine in the open jug which according to pool math was the amount neeed to bring it to 26. The current reading at 1:30pm is FC 26.

I have a question which I should have asked earlier. When we add chlorine to bump up the FC do we need to be very precise in how much we add, like measuring each quart, cup, oz, etc. or can it be a close estimate? My husband tends to look at the jug and say well that would be 2/3 of the gallon and judge it by sight. And do we need to check the level after adding or just trust that what the pool math says to add will bump it to that level?
 
I am a sight judger sometimes too. But of course exact measurements is the best way, and tends to allow more consistency. For the OCLT testing especially you will need to be very precise (and know exactly where your level is after the add is done), so we can monitor the exact overnight loss, but otherwise if it's 3quarts, and 3 cups and you want to use the full gallon that's fine, just retest 30 mins after to see where you end up It's most important to keep it at or slightly above the shock level at all times. (the main goal is to not let it drop below shock level ever, but too high of levels isn't good for your pool, and equipment. But it appears by the numbers that he's doing great.

EDIT: Pool math is very accurate, so if your numbers have been rising to the expected level, which they have, then there is no need to recheck after every single time since you are checking so frequently anyway, EXCEPT when doing OCLT, and then you need to ensure you know exactly where it is at.
 
Okay, that makes sense. I just started questioning it since the last reading indicated no loss and the previous one showed a loss of 4. So, if we add chlorine after the last reading of the day we should wait a little while and test it before going to bed so we have an accurate a.m. reading and know how much overnight loss we had.
 
Yes especially when checking the OCLT, you need to be sure you are continuing to add enough to get to and maintain Shock level. The OCLT is only done when you think you might have all the algae killed out, but want to be certain before allowing your chlorine levels to drop. But the 4ppm FC drop and CC level earlier today tells me it's still finding stuff in there to eat up, therefore depleting the chlorine, and combining with organics, so it will be a couple-few days yet before you'll need to worry about doing an overnight loss test.
 
You can either test a little sooner, or bump it a little higher say to 30-31ppm, (unless someone will be swimming during that time), but otherwise, either way will be fine. Do whatever is most convenient for you guys because you all know what you have going on today, and how often you are able to check it, so just adjust it to accommodate You, and your schedule.

I took the test at 10:40 this morning and intended to bump it up from 23 to 26 at that time, but my son left while I was on the computer and I couldn't reach the chlorine no matter what I tried...lol. He finally arrived home about 12:15 and I got the chlorine added. It's now 2:30 and my husband just did the test - FC 22 CC .5 We are adding enough chlorine to bring it back up to 25 since we should be home to test more often.

I know sun depletes the chlorine. Wondering, does it make a difference if its a bright sunny day, full sun on pool, or if its cloudy gray day but still light outside? I'm just wondering since its gray and cloudy today.
 
Oh no, bless your heart. I completely understand though.

Yes, It does have some effect on how much the chlorine gets depleted, but not a huge amount. It's not enough difference to require the levels being adjusted down for. So even on cloudy days, rainy days, we just go ahead, and try to maintain at the appropriate level for our CYA then we don't have to be concerned if the sun decides to start peeking out again, or not.

Have a wonderful day.
 
I had no chance go get on the computer last night, so here are the numbers from then and today. last night 10:00pm FC 25, today 4:50am FC 23.5 bumped up to 25, 10:15am FC 20 bumped up to 25, 1:30pm FC 25 not adding any right now. The pool is looking very clear. The black that was mostly concentrated near the steps at the shallow end are gone, maybe a spot or two, hard to tell .With our pool being pebble tec and dark, brown toned pebbles, it's hard to tell if there are any more black spots. Last night when brushed he still saw some green swirling around in the water like what happened when he could still see a lot of black spots, but a lot less green.
 
It sounds like things are heading in the right direction for sure. Try to set your bump ups a little higher say instead of bumping to 25 bump to 27-or 28ppm, so we can try our best to Never allow it to drop below 24ppm. That will sped things up for you a lot in killing it all out of there. You guys are doing great, and I think if you bump it a little higher with each bump, you'll be heading down the home stretch for completion in no time. Have a wonderful day :).
 
Last time my husband tested at 1:30 this afternoon, the FC was 25. He left it at that level and tested again at 3:30 and the reading is FC 26.5. How would the level go up? Could it be a difference in the measuring of a heaping scoop of the R0870 powder since heaping can vary? Just curious.

We are going to bump it up to 28 like you suggested.
 
Yeah, it could have possibly been a testing variance, on powder, water level etc., but LOL if you guys do figure out how to get your pool to add more chlorine to it's level all by itself, please be sure and pass your secrets along to the rest of us. I think the bump up should help prevent any drops below 24ppm. Remember though if anyone is going to be swimming allow it to come down closer to 24ppm. It sounds like the levels are holding better this afternoon too which is what we're looking for. Have a wonderful night :).
