Algae gone-water still not clear

[drband]

Exactly right. I did not advocate doing this in place of holding the CL at shock level. My experience w/ my own sand filter is that DE sometimes makes it more efficient at filtering very fine particulates from the pool water.

Shock level CL is the key to getting rid of algae (killing it).

Hi, DR,

Yeah, I understood what you were saying and my post was not intended as a criticism of yours....DE added to sand apparently has merit in some special situations.

My intent, rather, was to remind newbies and semi-newbies of the basics that work consistently. Exhaust the use of those basics (including POP) before heading to the pool store for the "magic" ingredient.

Some time ago, there was a poster here who had an algae bloom for around 45 days....due to improper use of chlorine.

Finally getting the chlorine up to the correct level, the poster simultaneously ran out of patience and bought clarifier. Pool cleared up and the poster was completely and totally convinced he/she had found the solution to algae......Clarifier!!!

Thanks everyone-
If I am figuring bleach calculator correct if my chlorine is 10 , then to shock I need to add 8 gallons, Is this right. Also how long do I keep it at 25, The water is blue and starting to clear. Also can you swim with that high a chlorine level?? MY grandkids are getting impatient (HA HA),

Thanks
Karen
