Halfdones's pool

[Halfdone]

Well, no real progress to speak of.

I've been keeping the chlorine around 15 for more then a week now. When I test it I am never below 7-8 and bring it back up to 15. I have been sweeping it and vacuuming the bottom and keeping the filter running 24/7, but the water is still very cloudy.

Here are the test results from this morning;
FC 11.5
CC .5
PH 7.4
TA 160
CH 70
CYA 25

I was disappointed to see my CYA go down. The highest I measured it was around 35. I did run some water to waste when I was vacuuming and refill but only dropped about 1" of water, that and a couple of backwashes I wouldn't expect my CYA to drop that much.

How long do I need to keep up the shock levels of FC? What can I do about the cloudiness? Can I send a sample of my water somewhere to get a better idea of why its cloudy? This is the first year we have used bleach as our chlorine and my wife is complaining about the cost (about $7-8 per day) and the results. We have never had this cloudy problem in the past. In the past we have used primarily granular chlorine, though I'm not sure what type (triclor, diclor etc.).

I did have a glass patio table break and dump glass in the pool this winter. While I got most of it out a while ago I just went in and swept, vacuumed out the rest yesterday by feel. Is there any change the glass was effecting the water somehow?

Frustrated,

Mark

I don't think the table has anything to do with this.

Are you losing more than 1ppm of chlorine overnight (from sundown til within 2 hours of sunrise)?

[Halfdone]

I'm not sure if I loose more then 1ppm overnight. I usually get to check it about 9-10am and its at 9-10ppm. I'll make sure its at 15ppm tonight at around 10pm then get up early to check before sunrise. I'll post the results in the morning.

Thanks.

[Watermom]

Don't have to get up before sunrise. Just within a couple of hours of sunrise should be sufficient.

[Halfdone]

Well I got up before sunrise and the level had dropped about 3.5-4ppm. Also as mentioned earlier my CYA level has dropped for some reason. I will be getting my CYA to try and get that leveled up to around 40-50.

I don't know why the bleach is getting used up at night with no sunlight. The pool is clean except for the cloudy water.

If you're losing chlorine overnight with no sunlight, then you have something in the pool that's consuming it, which is also probalby why your water is cloudy. YOu need to keep the chlorine up to shock level, and hold it there until the chlorine consumption overnight stops, running the filter 24/7 and cleaning it as the pressure indicates.

Thank you,

It seems the water is very slowly starting to clear. I have vacuumed it several times to make sure there is nothing on the bottom. I added another dose of CYA to try and bring the level to about 50ppm this time I added it to the filter since the sock method didn't seam to work for me. I haven't been having to backwash the filter hardly at all, I wonder if it is really doing anything. I will continue with the high shock levels as suggested. At this point I am wondering if we will get to use the pool at all this year, which would be a shame if we didn't due to all the cost we have put in in the form of equipment and chemicals.

I'll adjust again tonight and check in the morning to see how much I'm losing overnight.

My numbers this morning are;
FC 8.5 added about 243oz bleach to get back to 15
PH 7.4
CC .5
TA 150
CH 70
CYA didn't check, out of test agent
