Alota Bleach...

[pairadocs]

Setting: A once murky poop brown pool in Delaware that was opened one week ago by me, after alota questionable products added it turned bluish and milky overnight. Pool is owned by a 3rd year pool owner trying not to be a slave to the pool stores and find an avenue to learn about pool chemistry. Newb makes another attempt to remedy his pool, and fearfully posts info on the board in an effort to find our more without making veterans upset with his errors and newb questions and cluelessness .

I added 5 gallons of Kmart Shock (10% NaHypo) in an attempt to do what forum told me to do - elevate FC to 10-25 ppm because of cloudy water.

Water test at home and pool store were similar: FC 5, CYA 30, ph 7.2, Tot Alk 100, Ca 230...

So I added 5 more gallons of same stuff, and I hope to crank the FC to 10 - 25 overnight and hold for a while in an effort to get the milky, cloudy bluish pool to get right.

Used the bleach calc program I found on here in an effort to better approximate my addition of bleach.

I'm amazed at how much I must add.

I've heard a variety of days to a week or longer on the board for clearing the murky pool.

3 questions:

Paid $3.50 per gallon 10% bleach at Kmart Delaware - is that a decent/good deal?

How long do all of you think it will take to clear, demurkify the pool (30000 gal, IG gunite with DE filter)?

I also have acquired a liquid/drops home test kit - is Taylor product OK for this?

thank you

Bleach prices are up, but if you can get regular bleach for less than $1.75 / gallon, it's better than 10% at $3.50/gallon. Two gallons of regular bleach is the same as one gallon of 11.5% liquid chlorine.

How long and how much bleach do you need? Well, if you are relentless and consistent in your testing, then it will be faster and ultimately use less bleach. How much depends not just on the size of your pool, but how vicious an algae bloom you have, what kind of algae, what other contiminants, etc, and I don't know how to measure any of them. So the answer is: we don't know and cannot tell you "how long" or how much bleach.

I believe Taylor makes just about the best chemicals available for the mass market. Most of Ben's test kit is built using them. WHICH Taylor tests you have is important.

thank you.

can I overbleach my pool?

If you have a vinyl pool, definitely. It will bleach a liner if it's too high too long. Much harder to harm concrete with bleach. Follow Ben's Best Guess Table and use the Shock Level as the safe maximum for vinyl--it depends on the CYA level.

concrete pool here

Don't have to worry if it is concrete.
