I'm in the process of opening my pool (currently a green swamp) and am having some issues with my chlorine. I bought THIS below chlorine from Home Depot today which is supposed to be 10% Sodium Hypochloride. I added 3 gallons to my pool, waited 20-30 minutes and tested and had a FC of 1. Added 3 more gallons and still have an FC of 1 (should have shot up to around 12 with the first dose according to the PoolMath app). I then became suspicious of the chlorine and began sniffing it to see if it smelled strong (which it didn't). I even mixed around a 5-1 mixture of water to chlorine and tested it with the kit and it just stayed the yellowish color of the product.
Went back to a different HD and swapped it out for a new batch and it seems like it's more of the same. Am I losing my mind or is this stuff just not a good product? I've used it in the past with great success and the date shows it as being less than a month since it was made (so it's fresh). Two different batches from two different stores with two different batch dates and even stored in two different types of jugs (one solid white plastic, one heavy duty milk jug looking thing).
I've tried 2 different bottles of DPD powder and a different chlorine test and they all say roughly the same.
I've now poured 7 gallons into the pool in the last 2 hours and my FC level doesn't seem to be climbing. Is this stuff not chlorine anymore? What am I missing because I'm about to go nuts right now....
Also, after I do the FC test, if I let the water sit in the test jar for like 10 minutes it turns bright pink (like I'd expect when I'm testing). Is that normal?
