Re: Bought a Pool and it came with a houses.
Yes I noticed you had changed the pool size gallons as well, and I had already changed mine on PM too.

I had already checked on both gallon sizes though, and the weight difference in Borax between the 30000, and 30600 was only 1 oz difference anyway, so I'm not sure that's what was going on.
Here is a thought though, perhaps, before with the FC above 10, I'm curious if it could have been possibly reading higher than expected, and not actually being higher because of the high FC? Since you are now at 10, and it's still reading the same as it has since at FC of 14ppm which you noted in Comment #143 "(note that the PH readings appear to have held true from a FC of 14 which is pretty interesting)"
Here's something else to possibly consider. I'm not exactly sure how long it takes after the FC drops below 10 ppm for the pH reading to stop reading high, if it has been reading higher than expected prior too? (In other words, I don't know if it is an immediate return to "normal readings," or if it takes a day or so to stabilize back to reading normal).
That's honestly something I've not ran across yet, but would love to find out the answer to. I know someone following this Thread who may know the answers to these questions.
KIMKATS, who is one smart little cookie, and has been around much longer than I have, (lol she and a couple more taught me everything I know about the TFP method. LOL now if I could get them to teach me all They know I'd be in great shape. Perhaps she's ran across something like this or read something about this before, and can give us her thoughts on:
1) Why the amount Pool Math said to add "Prior to today with the above 10 FC level caused the pH level to appear to "Increase more" than it said it would.
Is it possible that the readings were what was high following the Borax additions because of the high FC level, and not necessarily the pH levels themselves?
2)Also if the levels were in fact only reading higher then they actually were, (it appears to still be doing so since the pH has continued to read at 7.4 ppm from his FC of 14 through today's drop to 10). Do you know how long on average after a FC drops to 10, or less, does it take the pH readings to return to reading "normally" again?
Should it be an almost immediate return to normal readings, or does it take a couple of days to stabilize after?
Also Mark, if that does end up being the case you would then need to adjust the pH because anything much lower than 7.4ppm will not be at a very comfortable swimming level for your eyes and skin, but wait until the pH test tells you where exactly your level is it. I'm sure you are very close if not right on it because no one complained of their eyes burning at that pool party, did they? That's a sure fire way of realizing your pH readings are off.
Anyway hopefully Kim will let us know what she thinks about it. Have a wonderful night.

TY Kim. I'm trying, and learned from a few of the best.
