Ok follow up from yesterday. Today I had off, to paint the interior of the new house! First I stopped at the local Ocean State to buy 16 gallon jugs of 12.3% liquid shock. Based on yesterdays Tf100 test results I wanted to get to it before working all day on the house.
Before adding the shock I moved the filter valve to waste and dumped water until the skimmer was close to cavitation but I didn't loose the prime. I don't know how much water was drained out but it dropped about 2-3 inches in the pool Then I ran the hose in the pool. I have city water so it should be filtered pretty good. I let it run all day until the water level was just over 1/2 the skimmer opening. Next I added the shock. Again based on what I had for test results yesterday I figured I needed to get the FC up to 35-39, there is a little play there based on my CYA test result being 90- 100 ppm. Not knowing the strength of the shock, since there were skids of it in the store and the sales guy didn't appreciate me looking into sealed boxes, I bought 16 gallons @ $2.99 a gallon.I added 9 gallons, turned the filter on non stop, and brushed the green slime off the walls, steps, ladder, and bottom. The pool is green and cloudy. I can barely see the bottom at the 4' level.
I finished up the house work about 6:00 pm and checked the water before calling it a day. Here are my current results. The FC is in the range I was shooting for, the PH is up but I understand that the PH reading is not accurate during a SLAM, is that correct?
FC - drop test - 72 drops- 36 ppm
PH 8.2 but off the scale
CC- -0-
TC 36 ppm since -0- CC?
CYA - 80 tested 3 times so I guess the minor water change out helped a little, question on this at the end.
TA - 110
CH - 300 ppm
So I left it like that, filter running, I won't be able to get back till about 7:00 tomorrow night.
Questions
1- Am I on the right track so far?
2- Should I run the robot vac yet? I wasn't sure if the water exchange would be as fast with just the vacuum going?
3-Will the FC set high enough until I can get back to test and add if needed?
4- Is using the waste port on the filter valve the only way to dump water using the filter? Should I try to do this again or wait to see when the water clears up?
5- How much shock do you think I will need to buy and once I get this done will it follow through the Winter or will have to do this over again next June?
6- I have to go to big car show in 2 weeks, I'll be away from Thur to Mon. I am assuming that the water will be good and I can use the pool before that. I have to see if I can get someone to add chlorine if needed.
I think that covers it, so far. What do you think?
Thank you
