Just wondering if this a cheaper/feasible option. Im running low on my CYA granules, barely 1lb left, need to order some of that. But was wondering since I need to raise my CYA anyways (its 40ppm right now) and I need to shock my pool, what if I just used Trichlor or Dhiclor (poolcalculator.com shows 33oz of Trichlor or 54oz of Dichlor) to kill two birds with one stone? Trichlor shows it will raise the CYA about 10ppm, Dichlor will raise it 15ppm.
Just wondering if this is just pointless if the cost of Trichlor/Dichlor outweighs buying liquid chlorine and me just buying the CYA (additional amount I need) separately. BTW I don't have any Trichlor/Dichlor sitting so I would have to buy it, that's why Im asking if its even worth doing.
