Hi TFP, I've been a long time lurker and this year decided to go all in on the TFP methodologies after two years of pool store ambiguity and hardships. I read pool school multiple times, and got started opening my pool on Wednesday.
I ordered my TF-Pro test kit, practiced with the samples, then got started. After opening day, PH was below 7 and CYA was below 30 (assumed to be 0) as I could fill the entire view beaker with the black dot clear as day. I then started to follow SLAM procedure, raising PH to 7.2, and adding socks with CYA to raise it to 30 CYA. I retested CYA after dissolving and circulating for a day, it measured just shy of 30 PPM. Great, time to start the SLAM, so I thought. The pool opening condition was rougher than last year, definite algae bloom and dark green color to it from our mild winter.
I vacuumed the majority of visible debris to waist. Then, I added my initial shock - 4 gallons of Liquid Chlorine to raise my 30k gal pool to roughly 12.8 PPM FC. Immediately after, I brushed a whole lot to suspend the algae and circulate the chlorine, pump running 24/7 at this point. I went back out to test the chlorine after 2 hours to make sure it was still in the appropriate SLAM target levels for 30 CYA, and I was shocked to see a 0.5 to 1 PPM of Free Chlorine. The test only required one drop to go from pink to clear. I tested a second time, and even compared against test strips I had left over from last year, all the same results.
Upon further pool school research, I stumbled upon Ammonia problems in the pool at opening. I'm concerned I possibly screwed up as I added 30PPM of CYA and it could be getting turned into Ammonia. I went to the store to prepare to break the lock, and I have 29 gallons of Liquid Chlorine on hand. Before taking next steps, I just wanted to confirm that adding such a large amount of chlorine to the pool won't be harmful. My understanding is that I should raise the FC by 10-12PPM every 30 minutes until it holds at less than a 50% loss after 30 minutes. Does this all have to happen synchronously, or can I break it out over the next couple of days?
Despite the FC being used so quickly, there have been noticeable improvements since opening - pictures attached.
PH: 7.2
CYA: 30
FC: 0.5-1
TA: Untested before SLAM
