Alota Bleach...

[CarlD]

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.

Don't have to worry if it is concrete.

Success Story:

Update - I can now see 4-6 feet deep and murkiness/milky pool is clearing - all due to the suggestions of you veterans and tons of bleach

thanks

keep that filter running.

and if you see the pressure start to rise too much and bumping doesnt help......backwash and replace the DE.

i was in a similar situation as you earlier this year and now i have crystal clear water.
