QUOTE=Swampwoman;1303797]Good morning, Richard. I have a wee bit of homework if you're up for it.
Today I'd like to catch up a bit and get a brief situation report and double check a few things so I don't lose track and misdirect you

I do have another party tonight, but have a bit more time as its smaller than last week's circus...
1. Visibility is clearing on the slope but deep end still elusive, correct? So after the shallow end vac, clarity to shallow returned and depth visibility continued to progress by at least six inches a day or more, correct?
Actaully, I don't feel that I lost any visibility after I vacuumed the shallow end. If I did it was neglible to my eye. However, after a day or so, I began to see more residue/silt on the floor in areas that I had vacuumed. But visibility has gradually improved a bit each day. However, I can't give you a specific measurement interms of inches each day. I can say that this, however. At one point I was using a tape measure to see how far down I could see in the shallow end. I strained to see the bottom. Then before I realized it in a few days, the bottom became totally visible. Same for the bottom stairs. So I went from almost clarity to total clarity as far as seeing the bottom in a few days.
2. You describe the water in areas as clear, green and sparkly where it has cleared, correct?
Yes, when I first approach the pool my reaction is wow, this water is clear, its clean, its almost sparkly. Today, I said to myself that it looks like a "sheet of glass", albeit a mint green one.
3. On average, how much bleach (and what percentage are you using) are you losing each day?
I am using aprox from 0 to 130 oz of 12.5 % chlorine per 2-3 hr measument depending on the Sun/time of day/length of time interval. For example, overnight last night, I lost aprox 3.5 ppm over a 12 hour period with heavy rainfall. The prior night I lost only .5 ppm. On the average I would say I am using about 1- 1 3/4 gallons per day.
4. How many ppm lost from night reading to a.m. Reading?
The prior night it was small, about .5-1. ppm, last night it was 3.5 ppm with a rainfall, and 3 hour additional time interval. I would say on teh average its about 1.5 ppm, give or take.
5. Do you have a new phone now to post a picture? If so, please do.
Yes, new phone will do.
6. What is the psi on your filter? What psi is normal for you?
Normal can vary from about 7 psi to 17 psi
7. How far open is your main drain right now?
Per your last directive, just slightly open.
8. Just a double-check. Take a white sock and elastic. Attach to a return. Leave it for an hour. Take it off and put your hand in the sock. Can you feel any sand at all?
Will do.
9. Just a confirmation: A. You used #20 pool sand, correct? Tell us what brand. (Last year there was a batch that was MIS-graded. I can go dig up the info once you report back. This is an outlier, so don't worry about it; it doesn't really change the course. I'm just trying to confirm that success is in our near future.)
The sand was purchased from Menards. It was pool sand, I believe its called #20 silica sand?
10. When you or pool guy changed the sand, did either of you check the laterals for cracks and ensure the fit was snug?
I did not do a thorough inspection as I was forwarned to be very delicate with them. Everything seemed to be in place from my nov ice perspective.
11. When you or pool guy changed the sand, did you consult the Triton manual to fill to the correct line, leaving enough space?
I changed the sand, and removed the old sand. My pool guy told me 300 lbs. So that's what I bought and installed ; 6 X 50 lb. bags. I had no manual and could not read the model number on the faceplate, as it has weathered over time. However, the amount of sand I installed appeared to match what was in the machine.
12. Pressure relief valve...you said you didn't have one...but Triton manual says its a screw type (see link). Maybe your model is different, but I just wanted to make sure you can relieve the pressure if you end up doing further maintenance.

There is a pressure valve on top of the machine that is a screw in type thing. That is where the pressure meter is located. When I changed the sand I did unscrew the meter, and when I reaattached my readings appeared to be off. My pool guy reeassembled it and it appears to be fine.
Thanks in advance for your answers. If possible, please post specific answer under each question.
Cheers to clear!
