Hi All.
First ever pool opening. I'd like to see if my thinking is moving in the right direction on the opening process. I might be overthinking it so want the folks here to take a look if possible and provide their expertise.
Pool installed April 1st. Will have electric hooked by up end of April. Therefore no water circulation at this point. I've run the robot a couple of times to clear out some of the debris from the install including worms that have crawled into the pool.
Pool Opening Process
Another question I have is the levels I've found from reading the SWG manual, TFP and various websites show mostly the same acceptable levels of chemical ranges except for CYA and FC. Curious on why it is a bit different at TFP. See table below of the various information I've gathered on chemical levels. As of 4/2022

Thank you in advance for any thoughts and advice!

Pool Opening Process
- Start up system and follow start up instructions for equipment - pump and filter. Keep SWG and Heat Pump off for time being. Let water circulate and get familiar with equipment.
- SLAM pool. Water has been sitting for over 20 days without any chemicals. The water is by no means green but is looking a bit cloudy.
- Increase TA to 80-120
- Lower pH to 7.2 to 7.5 range
- Increase CYA to 30
- Increase FC to 12
- Run the following tests per SLAM article
- CC <= 0.5
- Pass OCLT
- Water is clear
- Additional Notes:
- Pump runs 24/7 during process
- Continue process until SLAM tests are passed.
- After SLAM process
- Increase CYA from 30 to 70-90 range
- Add SALT to achieve 3000 ppm
- Turn on SWG and set to 60% per instructions.
- Additional Notes:
- Start with Pump Run Time of ~5 hours (loosely following TFP time of 4 hours)
- Test TA, pH, CYA, FC daily and adjust appropriately (daily testing until I get a hold of the process). Adjust SWG chlorination level depending on test outputs.
