If stain comes off with vitamin C, likely iron. Two options: keep the iron constantly dissolved in the water by use of a sequestrant solution (Jack's magic) or replace the water in the pool with water without iron

If your pool is plaster, raise the hardness to 250. If fiberglass, 220. If vinyl or above ground, ignore. When pH hits 8.0, lower it to 7.2 with muriatic acid. This will lower total alkalinity over time. You will notice that since your total alkalinity is on the higher side, it will cause...

48 hours of SLAMing for liquid poop should be good. Just remember that you should round your CYA up to 50. Backwash after you are done and leave anything you used to remove the poop in the water so that it is exposed to chlorine. When chlorine level falls below SLAM level you can resume...

Total chlorine of 5 and free chlorine of 3 equals combined chlorine of 2 which means you should SLAM the pool (if those numbers are accurate). What test kit are you using because the K2006 or TF100 don't give a total chlorine result... they give a free chlorine and a combined chlorine result...

Remove all solid contents with skimmer net... SLAM for 24-48 hours, then backwash the filter Leave the skimming net in the pool during the SLAM so any residue on it dies Has the child been sick? Poop liquid or solid? Sick and liquid means more aggressive response. Chlorine level for SLAM...

Why do you want to use pucks? Your CYA will increase. Just let sunlight burn off the extra chlorine and don’t add so much liquid next time. No big deal. Safe to swim up to a SLAM level for your CYA.

Your total alkalinity drop won't be instantaneous. It will go down gradually. Stop measuring total alkalinity so often... just worry about pH/FC/CC for now. pH and total alkalinity are related. If your pH is wacky... your total alkalinity is probably wacky. If pH is fine... then TA is...

Try a 24 hour SLAM and see if that doesn't sort things out. For a CYA of 60, raise free chlorine to 24ppm and hold it there for a day.

Ok, then that points us more toward the CYA level being lower than you might think. The other explanation for chlorine usage going up would be the 4th of july party... but that would have probably stopped or gone back to normal once all the waste in the pool was taken care of by the chlorine...

They sell it for 2.99/gal and occasionally have coupons and sales. Might be a good source for you in the future.

The "other" ingredients are water and a dash of lye. It's the same stuff you would buy at the pool store. No worries at all in using it. Enjoy your free stuff. In checking it seems that there is an Ollie's near you in Ft Myers. Perhaps your friend shops there. ;-)

It's 10%. Bought the same stuff from Ollie's. I think the date code (from what I can see is 19 120s?) is fresh. Should be nearly full strength remaining if so.

EDIT: ignore me

To clarify what above poster said, "super high" chlorine readings that render pH testing inaccurate are anything over 10ppm (which really isn't that high in my opinion). But just want to clarify what he meant by "super high".
