I had a question,
This year (we had a mild Winter here in PA). Last Thursday I pulled the cover off the pool and the water was very clear but had a slight green film at the bottom. No biggie, "this weekend, I'll pull the cover early and get everything going". (Even though the weather here got a bit cold again).
Well.... come 3 days later on Sunday, I open up to a pretty green pool. (Very fast - I was shocked - no pun intended). I'm sure I caught it early but WOW, did that move fast.
I've only had this once in the past and like the last time, I followed :
Turning Your Green Swamp Back into a Sparkling Oasis
AS USUAL - with the great advice in that thread, by last Wed, I had shocked the pool (since the previous Sunday - 3 days) , chlorine levels had stabilized with no real drop between my 9pm check and my 9am check on Wed.
So All is good, the water is a nice blue color, "milky look" is gone etc.
To play it safe, I keep shock level at 30, 2 nights after my levels had stabilized. (taking me till Friday when I check again and see no real drop from the night before). All my levels now are at my desired levels from the chart I keep and all is good. (By the way.. time to order more supplies for my TF-100 from all those drop tests.)
Every day since this Thursday I see an improvement. (Filter has been running 24/7 Since last Sunday). Everything has been "stable" since Thursday/Friday. Judging by the visible area of the border and pool walls, I see a bit further to the bottom every day since Friday and while brushing, I can just see the brush as the bottom now as of today.
I'm using a Sand Filter and I know this can take a bit longer to clear up the water. I've also added a little over a 1/4 cup of DE mixed with a gallon of water and added it to the skimmer (Pressure Increased about 1psi). Normally I don't use any DE, - the filter has been doing just fine on it's own.
Just wondering how long most of you using sand filters seem to find it takes to clear the water?
I'm about 100% sure everything is dead. (I can post some updated numbers tomorrow). Right now, I'm NOT using the SWG but have been using bleach and I've noticed the the high chlorine levels have now drifted down to about 7ppm. I also have a Trichlor puck in the skimmer for no other reason than it makes me feel better
(I'm leaving the level a bit high at this point but I'll let it come down to 3-4ppm in the next few days and then when everything is clear, I'll add salt and fire up the SWG.
Just wondering about the time to clear. I'm guessing another 3-5 days or so using a sand filter?
