Foreword: I've had major algae problems, it was so bad I had black algae build up between the mosaic tiles on the pool floor and yellow tint (not sure what that was everywhere). So I drained my entire pool, and gave it a nice acid bath (HCI - hydrocloric acid) so the black algae and the yellow stuff that built up I could wash away. It took over 10 hours to wash the pool as in some places the build up was so bad I had to go back 3-4 times with acid, power wash, acid power wash, etc to get it to come off.
Here are some pics of our empty pool after cleanup and before i started filling it, its 15,000 gallons (56,xxx liters). Sidenote: NVM the jungle of weeds, I have to replant the grass LOL
Question1: When I start filling it from scratch, will it have CYA = 0? (My guess is yes, but id like to know for a fact)
Question2: I used pool calculator, entered my pool size and it told me my shock level is FC 10 (on CYA=0). Then I used the calculator to calculate how much liquid chlorine I have to add and it said to add 115 oz of 16% bleach (bleach=liquid chlorine?)
**Dumb newb question** Does that mean I have to add 115 oz to shock it? Or I screwed up and misread...
Question3: We cannot buy stabilizer here (When I asked for CL stabalizer they were like huh -- is there a household name for stabalizer?) , they are clueless when I ask at the 3 big pool stores. So, since dichlor (or triclor?) pucks have CYA in them, should I just put in some pucks to stabilize? (We have pucks that are chlorine+stabalizer only, and also have ones called multi-combi which contain chlorine, algacide, and stabilizer)
