Tested again in better light this morning, FC- 11 chlorine dial stayed at same setting not sure why this went up? CC < .5 TA- 100 CYA- 30 was definitely 30 or less could almost see dot when tube was full of water.

No it is just a dial, I think I’m going to have to recalibrate it, I’m almost at the lowest setting already and 3-4 years ago it would stay at halfway.

The ORP reading never really correlated to what my test would come out too. And the rep for the system said I should pay much attention to it, but I know I’ve had to turn the dial almost all the way down.

Taylor drop test, I have an automatic chlorine feeder, it’s hard to tell exactly what the CYA is, I feel it is always partially subjective. The “pool store” said it was 34.

I seem to always run high on my CL this morning I tested the following, FC-8.5 CC- .5-1 IT WAS 5:00 AM and dark PH- 7.8 TA-100 CYA-30-40 The kids were complaining about their eyes burning at lunch time and said the water tasted salty, would bringing up the CYA still be the first plan of action...

If your CC is above .3 I thought it means you need to shock the pool?

I've been having high CL readings pretty consistently but still have CC at .5 or above often. This morning these were my readings; FC- 7 CC- .5-.8 PH- 7.4 TA- 100 CYA- 20 I am using liquid chlorine on an automatic feed system. During these hots days I am having a lot of swimmers and I am...

So the sales guy that installed my automated liquid chlorine/acid system came by to do a post installation check up and while he was there he took some readings and sent me this screen shot, see attached. I am assuming this is a computer generated reading? The CCL is what got me, if it was...

my own kit

So I should wait until the winter when I do not need the FC? Do I really need all this extra stuff too? Also Required: 1/2 gallon muriatic acid or 1 lb pH decreaser, per 10,000 gallons of pool water. Also Required: 12 ounces of Jack's Magic Blue Stuff, per 10,000 gallons of pool water...

It changed the color but only after I left it over night. You can see the change in the second picture mid left bottom, It is a ring the middle of the ring looks like its still stained but there is a clear clean circle where the puck sat.

no one has any ideas on the stains from the pictures posted?

Yes mistype, cc of 270 would be bad, not sure if that could even be possible :eek:

Yes stable, isnt that a little low? Shouldn't it be between 80-120, oh thats what I always went by but I see TFP recommends 70-90.

Readings today with pictures FC 4.8 CC 0 PH 7.4 TA 70 (NEED TO ADD SOME BS) CC 270 CYA 60

A few days of readings but these stains have been here for a while. Old pool replastered 4 years ago. Tried rubbing the puck too, nothing. I had to add some calcium because levels were staying low. I did have to slam at the beginning of the summer I think stains were already there 8/10...

I have a large area with discoloration and it is only on the shallow end 5ft and less. It doesn't come up with brushing so I tried putting a puck in, left it for 30 min and nothing, got in and scrapped it on the bottom and it didn't streak. Some kids were able to scrape their initials on the...

Less than a week later pool is crystal clear. Saturday people started swimming again, tested after the day was over. FC- 3.5 CC- 0 CYA- 60 PH- 8 Added acid and bleach to bring levels to recommended levels. Also downloaded POOL MATH so, hopefully I can stay on top of this. Thanks everyone

Well didn't get a chance to get over and test yesterday afternoon. This mornings partial test results FC 7 CC 0 PH 7.6 CYA 70-75 Pool is clear, backwashed and rinsed this morning, then just added more problems-water was low so put 2" hose in pool to add some water to make sure water level...

Took pucks out of feeders and took readings FC still high 13.5. CC 0

yes

Well, for what it's worth from my camera the pool looks blue, will not be able to test until tonight. I do have a guy coming look at installing a liquid feeding system today, Pumps & Feed Systems | AquaSol. Only found one thread about automatic controllers and it was for just PH, I am sure...

Tested this morning and the FC is 25? Is it normal to just jump up that high from 3 to 25 and I just added 5 gallons last night

Just tested fc 3 and cc was 0.5. Water doesn’t have green tint anymore just cloudy. So I backwashed and rinsed then added 5 gallons of 12% bleach for the night will check back in AM. The cloudiness clears up quick or is that what takes the most time?

Drained about 1/4-1/5 of the pool and refilled with fresh water. Added 1 gallon of acid to bring the ph down and then added 10 gallons of 12% bleach last night. This morning took readings (did both test dropper and powder because I must of did something wrong I am guessing), levels below...

I added Metal Out last thursday, and maybe 1/2 gallon of acid last Monday. PH- 8 real high (assuming bc of rain) cya- 95 chlorine- 0 (fresh rain water)
