This is my first post, so here goes. Read as much as possible about TFP method and had first success at lowering 100+ CYA to 40 by replacing 60% of water . Also had some small patches of yellow/mustard algae in the shady spots, so I scrubbed every square inch of floor and walls with nylon brushes. Got my TF-100 kit in the mail late yesterday. Used it for the first time this morning. Felt like a grownup not having to run to the pool store. Here are the results:
FC: 4 (FAS/DPD); OTO 3
TA: 240 (tested 2x, same result)
Pool is crystal clear and has been the last 3 days. Most of pool is in direct sunlight for 11 hours in summertime.
I followed the directions to the T with the test kit, wiping the tip after each drop of R-0009. Can the TA reading be right? Yesterday, the TA reading from the pool store was 150.
So far, this morning after the test I have added 68 oz bleach and 65 oz of MA based on the pool calculator.
I set the pH goal on the pool calc to 7.2. Will follow the article on lowering TA by lowering pH then raising pH and repeating. Just feel like I have a false TA.
