I’m a long time lurker on TFP and currently follow the recommended best practices for maintaining my pool and equipment (in signature) i.e. liquid chlorine and acid dosing, self testing water multi x per week with TF-100 kit and many other best practices.
I purchased my house 10 years ago with the pool already built and will be doing a drain/refill for the first time due to calcium hardness being above acceptable and manageable (very hard well water). While the pool is down I plan on doing a deep cleaning of the sand filter (garden hose method which I do twice a year) and adding a SWG to my system. I’m having water hauled in from a municipal source and have a few questions about rebalancing the water after the pool is filled and, as the thread title states, a question about a method I’m considering to add CYA (granular) during the balancing process:
What is the proper order for balancing the water?
—- My current plan is: CYA, PH/Alkalinity, Chlorine, salt, CH (if needed but doubtful).
Can I add the granular CYA directly to the sand filter on top of the sand through the maintenance / sand fill port when I’m done with the deep clean?
—- I plan to set my CYA level at 50ppm since I will be adding a SWG which will require a little over 7lbs. In the past I’ve added CYA when needed by putting it in a sock in the filter basket but this seems impractical for this large of an amount. Since I will already have the sand filter open, and plan on running the pump at full RPM for a few days after the refill, I am considering putting the CYA directly on top of the sand just prior to buttoning the filter back up and restarting the pump. My theory is since the CYA is granular and much courser than the sand the water will pass through it just fine and dissolve it in the process which will be faster / less labor intensive than doing it traditionally over several days. This seems like an almost too simple of a way to do it that I haven’t seen suggested or tried before so I’m thinking I might be missing a potential problem. Any reason(s) NOT to do it this way?
A quick note on the SWG. I plan on installing it while the pool is down but don’t plan on running it until the water is balanced and stable.
Thank you in advance for any input / suggestions and thank you very much for all of the help and knowledge I’ve gained over the years from this site and its members.
