Poolsean,
I agree, all the cal hypo tablets and capsules I have seen are designed for using in the skimmer or some of them can also be used in a NEW floater that has never held trichlor. IMHO, they work best in the skimmer. They should not be used in a trichlor feeder which is pressurized! It is possible for an explosion to occur.
So, I should use these by dropping them in the skimmer? How many at a time?
I tried shutting off the pump to let the pool settle overnite and it didn't change it's appearance at all. It did lose virtually all it's chlorine. I had 14ppm FC and 2 CC before, and this morning it's .5 and .5. Nothing else changed. I raised the pool level in the afternoon to the normal level several hours before shutting down and brushed everything. I think I found some additional algae that missed the chlorine shock last week. That's the only thing I can figure that would explain the big loss in FC.
I'm finally making some progress with my pool. I can see the bottom in the 4' section and as of this morning my tests showed
temp-77
FC-6.5
CC-1.5
ph-7.5-6
cya -50
TA-300
The TA is my next area I'm going to work on. I will start adding the acid and aerating the pool. I found an interesting setup in my inherited box of pool stuff. It has a fitting that plugs into the Polaris jet and turns 90 degrees and is adjustable height before another 90 and ends with a parallel sprayer head. I checked it, and it is perfect for spraying 20 streams of water into the surface of the pool. I can aim the spray 360 degrees so I can have a fountain or straight into the water with maximum force. I remembered seeing it, but had know idea what to use it for until I saw the pictures in the other thread.

FC 6.5, CC 1.5, CYA 50?
You need to keep your FC at 15 or it will never clear. I'd worry about that before T/A since it's still cloudy.
I haven't dropped the chlorine those last readings were first thing in the morning after putting the FC at 20ppm last night.
I put it back up and kept it all day. Is there a reason I can't do both?
I got some muratic acid and dropped the ph to 7.2 and installed, what turns out to be a rather neat fountain. The TA has come down to 230 just today. While running it looks like this:

Well, you can, and at 7.0 to 7.2, the chlorine will be more effective at killing algae than at 7.6-7.8, so it will help.
I just don't want you to lose focus on your primary task--killing the algae. Nor was it clear that the measure was between shocks/before the next scheduled shock.
That's good to know. The ph had climbed back up near 7.5 again, so I just put in another quart of acid. This morning the readings were better.
FC-14
CC-1.5
ph-7.4 (a guess, but close, a lot redder than 7.2 where it was at 7pm)
Last night, I turned the sprayer head into the pool basically straight down and it drives the streams into the water several inches. From what I read in the other thread, this will aerate the pool better.
The main drain is visible now and the water is getting some sparkle to it. Finally.
Almost there....just be patient and persistent!
Everything has been on hold for the past 4 days. Closed the pool cover and haven't been able to open it while we've received 6-8" of rain. If the weather guessers are correct, 2 more days and 2" of rain before it clears off.
I'm sure water temperature has cooled off because the warmest we've been is 74 degrees since we closed the cover.
Had a break in the rain, the water went backwards. No FC- cloudy, can't see the 4th step. Shocked the whee out of it, I stopped counting at 25ppm. Then the rain came back.
