Thank you pool doc!! Your the best.....

I only use a leaf cover for the winter. I close the pool per instructions here pretty much. It always seems to turn green though. I would say I though the leaf cover lets the sun shine in all winter and thats why it turns green. I have not used the polyquat the past few yrs. Could that be it?

This yr I used some algae stuff from the pool store that was on sale. 1 gal for $10 bucks. It was light blue and you added 1/2 cup are so. I added it throughout the winter, but it did not work. Ok so I will either

a) need to get a solid cover for next yr, or
b) do what I am doing but make sure I add polyquat only. Add some periodically I would assume.

I will need to read some more here and refresh my self with pool closing. OK, well I need to think ahead for next yr and not let this happen again.

Ugg... This sounds like its going to be a carbon copy of last yrs nightmare...

OK day 1.

I went out before bed at midnight and raised the cl to 12. This morning it was at 2.5. Here is what the pool looks like. Gee almost no green and I can make out the bottom.






Ran the filter all night on low speed. So raising the cl back to 10-12 again.

I wonder if its best just to use bleach at night so not to waste it from the sun dissipating it?n [ Yes! PoolDoc ]

Keep you FC at shock level as much as you can. Letting it slip sets you back.
You may want to keep your pump on low speed as it seems to be pretty large for a 16" sand filter. You wouldn't want to push the junk through your filter.

Hey you are exactly where I am at in the pool opening process. Except I cannot get my chlorine level up. How much bleach did you add and did you add it all at once or a little every night? I'll be following your thread closely as my pool is apparently in the 'ammonia eating the chlorine stage' also. And for what it's worth I used a solid cover, super shocked & super chlorinated it at closing, and still had green, so don't feel too bad!

Sunlove,

What I am doing know is keeping my chlorine level at about 12ppm. I have a taylor 1515 kit so I am able to test the high shock levels.

Taylor K-1515 @ Amazon

I test every two hours or so. I lose about 4 ppm or so in that time. So I use the bleach calculator thats on this site somewhere to tell me how much to add to bring back to shock level. I add throughout the day every two hours. For my small pool it seems I have been adding about 3/4 of a gallon every two hours to get me back to 10-12 ppm.

That's what I have been doing. It cleared somewhat more today but still cloudy. The green is almost gone and looks white or blue somewhat. But last year I had the cloud for a month or so I believe.

I over shocked last year and the metals came out and stained my liner. Search my posts from last year and you will see what I am talking about. I even need to go back and re-read my old posts. Sitting here thinking about it I may think the pool doc had me raise the shock level to 15. But I cant be sure until I re read. I have a lot of patience so I am in no rush. If I do this methodically I think I will benefit better. Also my pump/filter has been running on low 24/7.

Sunlove,

In a 7500 gallon pool, each 1 cup of 6% bleach will raise your FC by 1 ppm. Each gallon will raise it by 8 ppm. You can use these as a guide to figure out how much to add. The key is to add enough to get to shock level (dependent on your CYA--see the best guess chlorine chart linked in my sig) and then test and add more as needed to get back up to that level until the pool clears. The more consistent you are about maintaining the shock level, the faster it will happen.

[Lawrosa]

Well Looks like I am on the same path as last year. I guess I am doing correct by checking every 2 hours and adding bleach to keep my levels at or above shock. [ Not necessary -- 1 or 2x per day is enough - PoolDoc ]

I have the filter going on low 24/7. I vacuumed again today with the sand filter. I got very little. The pool is clean but cloudy. I then disconnected the sand filter and installed the cart, and am now running cart only on low.

I am know raising my shock level to 15ppm. No higher. Since this year I have the kit to test this high, I wont be guessing. Last year I shocked too high and cause the iron to stain the liner. Thanks to Ben/pool doc that pink stuff worked.

Anyway that's where I am at now. I guess this is day two. I started on the 16th in the pm. So tonight will be a whole 48 hours. Note: As I type this now I have currently used 10 gallons of bleach and nothing else. ( except that 1 lb of CYA)

Here are current pics:

Just checking in. Pool looks the same as in last pics. "CLOUDY" blue!!!! Added bleach to 15ppm or so levels last night. This morning 11.5ppm. Pump running 24/7.

Hope this helps folks here. I guess it will give people a time frame of how long it will take a cloudy pool to clear up. I am being very diligent in keeping shock levels up, and have been for the past few days. I started this shock process on 4/16 in the PM. So tonight will be a complete 3rd day

Just re read my thread from last year and basically I am doing the same thing as last year. Although since I have the 1515 test kit I can more accurately add the proper amount of bleach. And hopefully not bring the metals out this year and stain the liner.

We will see.
