I have a high alk and thinking of dropping it using the sticky thread. My test are as follows.

FC 4
TC 4
PH 7.8
T ALK 200 - 210
Ca Hardness 230-240
CYA 35

Pool volume 13000 to 14000
24’ above ground
22 “ 200lb sand filter with about ½ cup de added
2 hp pump
BBB method

Pool looks great but the Ph goes from 7.4 to 8.0 in a few days. I have a fountain like pictured below.



Questions
  • Will the fountain I have work?
  • Can I let the kids in the pool with a ph of 7?
  • How much muriatic acid should I have on hand for this procedure? (Lowes is 45 minutes away)
  • Will the Ca precipitate at this low of ph?
  • What are the long term effects of just leaving it alone and adding acid weekly?
  • I am going to salt my pool for that oohhh so good feeling talked about in the other post. Do I need to wait untill after I drop the ALK?
I am shooting to do the procedure after the weather warms up. I know the fountain will drop the temp and the pool is way too cold (for me) right now.
Thanks in advance
Steve
