Alota Bleach...

[CarlD]

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.

took a total of 30 gallons of bleach over a couple of days, keeping the FC high and 24/7 running DE filter and I added filter socks (who knows if it really helped, but they did have alota fine particulate grime in them each morning)....and now I have crystal clear water, 9.5 feet deep, all the way to the bottom I can finally see

Oh, they helped, alright! Congrats! You've been down a long tough road and the end is in sight. You might even be there by the time I get this posted.
