First a confession...I cheated on my SLAM.
Started SLAMming and pool was just eating chlorine. I ran out of one of the chemicals to test the chlorine. I had to order it online, as no one carried it.
(Side note: Leslie's Pools will never get another penny from me for anything! Sent me on a wild goose chase to 3 different stores, each one saying, on the phone, that they had it, but when I showed up, they tried to sell me the wrong thing. One clerk argued with me that I was wrong and the testing chemical I was asking for was NOT for chlorine, until I showed it to her on Leslie's web site).
So while I waited, I continued to add the same amount of Chlorine that I was previously. Test chemical arrived and I passed all the tests (water not crystal clear, but very close). And I passed the overnight test.
Pool was still consuming chlorine like crazy, so I tested for ammonia and came up with less than .25 ppm. But Chlorine seemed to stabilize (and no CC, so I thought the ammonia was not a problem).
I usually test my pool everyday there are swimmers, and every other day if no one swims. Except Tuesdays. On Tuesdays I am out of the house from 4 am until 10 pm. So Wednesday morning I tested and Chlorine was 0 and Combined Chlorine was 0. I quick added chlorine before I left. Came home to 6 kids in the pool and found out there were about 10 the day before.
Tested again and found only 1ppm of Chlorine and no combined chlorine. This had me confused. I added more chlorine and after an hour I did a full test.
CYA between 30 and 40
Ammonia .5 ppm
Now I think the bather load was too high for my little pool and this caused the ammonia to go up and the chlorine to go down. Does this seem right?
I will do an over night test and post the results tomorrow morning.
Do I need to address the ammonia problem? Or was it just too many people using the pool?
Sorry for the long ramble.
