So I went to my local Walmart and looked at the prices for my options for sanitizing my 80,000 liter vinyl liner pool. CYA levels are currently at 0.
- 5 liter jug of 4% bleach is $1.98
- 7kg trichlor pucks cost $39.87
- 454g of HTH sock it shock treatment costs $3.98. i am assuming this is 65% cal-hypo, it does not say on the bag anywhere.
So according to the pool calculator, to get my pool from 0 FC to 4 FC would require the following:
- 7500ml of 4% bleach
- 350g of trichlor
- 496g of 65% cal-hypo
This works out to a cost of $3.00 for bleach, $2.00 for trichlor, and $4.00 for cal-hypo. I have always used 6% bleach, but now my walmart only carries 4%, and it seems the pucks are now the cheapest option.
Have I done this calculation correctly, and is there anything else I need to consider?
