1. the only reason I'm adding shock (dichlor) is to get CYA
2. this is a new fill (had to empty to replumb for new pump/filter/swg) so current levels are 0
3. I'm confused about the shock. according to the pool calc I am working with 1400 gallons, (I know, very tiny) so the calculator says that for a CYA goal of 70-80 (swg and vinyl pool) I need 13-14 oz of stabilizer. However, down under "effects of adding chemicals" when I choose dichlor, it says "adding 16 oz of dichlor will raise FC 47.4 and CYA by 43"
Then of course on the shock package it says to only add 1 oz per 1000 gallons which would be adding 1.5 oz.
And if we can't get back into the water until the FC is under 3 and I'm raising it to 40+... when will that be?
So-- do I need 13 oz (from calculator), do I need 26 oz (based off the the "effects of adding chemicals" at the bottom of the calculator), or do I really only add 1.5 oz like the package says?
AND... I know you have already told me that the mere act of opening the pack of shock will NOT cause nuclear holocaust even though that is what the package implies...I'm still nervous. If I don't need the whole package can I save it? and how? and how do I throw it away?
thanks, I swear once I get it up I'll be fine.
