still have green pool

[mikemedic]

Ok, I posted 'the green pool syndrome a few days ago'
Here is my status:
Since my CYA was 120 I decided to drain the water half way down.
My chlorine level was at 25 for two days and still is green
FC=25
Alk=100
PH=7.8
CYA=120

I noticed most of the algae is on the bottom cause
I brushed till i can't brush anymore

So I am filling my pool bacl to the normal level now. Just added a 32 ounce bottle of polyquat, and have the filter on recirc.from the bottom drain to dilute up the algaecide.

I keep brushing, wife thinks I am crazy adding good water to algae water but it's not safe to completely drain the pool.

I will check the levels later tonight after pool fills

16x32 vinyl pool= 21000 gallons

I will try some clarifier later.

And yes I replaced out DE filter last fall with a Hayward 250 lb sand filter

Hopefully my CYA goes down

ANy other thoughts

I would add nothing but bleach until the water clears up, just my 2cents. good luck

Are you keeping your Cl level at 25 all day, or are you letting it yo-yo up and down? It may very well take several days to get it all cleared up, so your best bet is to forget the clarifier and just add enough bleach to go back up to 25 ppm. If you can test and add more 2-3 times daily, that'll even help it clear up faster. Keep brushing daily, and keep your filter running 24/7 until it clears up. Be patient, and it will clear!

Will do, I am hoping the cya drops form the dilution method

Its hard to see where I have brushed the algae

Will the polyquat and the high chlorine kill the algae enough to see the stuff on the bottom?

[aylad]

The high chlorine will. As the algae dies, your pool should go from green to a cloudy blue. At that point, hold your shock level a couple of days longer, then you can let it start drifting back down to your maintanance level. Leave your filter running--that's what will get it all out of your water.

Just curious but why did you go from a D.E. filter to a sand filter? This is going to make the cleanup process a lot more time consuming and tedious

[cschnurr]

Brushing the bottom will help mix the algae up so it can be attacked more evenly by the chlorine and picked up throught the skimmer.

But vacuuming the bottom might help to remove the dead algae as its killed off.
