I need to add some CYA to my SWG , vinyl liner pool to bring up my level. I also need to add some baking soda to bring up my TA a smidge. PH is good at 7.6. Always wondered, whats the best order to add these and can I add baking soda and CYA at the same time or should I wait between? I know CYA can decrease PH but I'm not sure how much and if its worth worrying about. Just Cyrus on the forums opinion. Thank you.
