After the slam process is complete and I work on adding stabilizer to get my cya back up, what should my fc level be during that process (salt water pool)? Thanks!

Correct, when I tested CYA on Sunday it was zero....water completely clear and I could see the black dot. :(

I have added liquid bleach to bring up to slam level all day yesterday. Last night i tested 20min after adding bleach according to pool calc and fc was 33. Tested hour later fc 26. This was at night. This morning fc back down to 1. Yesterday evening the water was a lot less cloudy (could...

Since yesterday afternoon I've added 3-16oz shock (48% cal hypo) and my fc will only go up to 1. At the beginning of the season I add 2 bags and my FC will go to close to 30. I'm so confused.

Stabilizer is granules. I've have the container going on 3 yrs...does it get old?

I'm battling with cloudy water, no FC, no CC, no CYA.... 5/21/17: water clear, FC 4, CC 0, ph 7.5, CYA 35. I added stabilizer to bring up to 60 according to pool math. Last Tested pool Thurs 6/1, FC 4 still didn't test CYA. Swam Friday for 1 hour, went away for the weekend so didn't test...

gosh I hope so.....stressful! Should I increase my CYA since it is 40 and should be 60? Or during SLAM should I not worry about that one either?

Update on testing #s after several days: Water still slight cloudy but can see bottom and drains. When brushing sides it doesn't make water any cloudier. Sides are not slimy. But I am still losing FC overnight. Been continuing SLAM process with liquid bleach. Water temp 50. 5/22 PM: FC 24...

Tested water just now: FC 29 CC 0.5 As long as I don't have a drop in FC overnight with my reading first thing in a.m. am I okay to let FC fall down to normal range?

Update - I took a pool water sample with me before leaving for work so I could get ammonia test strips when pet fish store opened. Just picked up ammonia test strips and tested with pool sample. It appears to be zero (attached the pic). The pool sample was 1.5hrs old, so not sure how much...

I added 64oz of cal-hypo before leaving for work this morning which was according to the pool calculator. Do I continue to add liquid bleach today (amount according to the pool calc) and test an hour later and add more until I can get it up to the fc shock level (24)?

TF-100. How much chlorine do you think I need on hand? Should I use my cal-hypo shock bags instead?

Opened pool 5/17.....levels tested using TF-100 kit: FC 0 pH 7.0 TA 70 CH 125 CYA 0 Water dirty/cloudy but not green. Couldn't see bottom drains. Added cal-hypo (48%) 16oz bag and 64oz solid stabilizer. I'm in Ohio ...all week has been cold and cloudy (temps 50s). Added salt 5/18 and salt...

Re: Why is my Autopilot Digital Nano unhappy with pump spefl Our tri-sensor appeared to look fine (flow switch, etc no cracks and not bent or twisted) however Autopilot sent me a new one to swap out and try (thanks Sean!). Swapped out the tri-sensor and I was able to lower the pump rpms to 1100...

Re: Why is my Autopilot Digital Nano unhappy with pump spefl The bypass check valve is closed at lower flow. It was hard to see whether open/closed since it is spring tension but when I turned the pump way up I saw it open up. I am not sure how much more I can ask PB because he stated when...

Re: Why is my Autopilot Digital Nano unhappy with pump spefl If the flow switch is closed is it still producing chlorine and the digital nano shouldn't be displaying the error "error - purifier off check flow"? Trying to make the correlation between the check flow error and flow switch (opened...

Re: Why is my Autopilot Digital Nano unhappy with pump spefl Ok, I will check when I get home this eve.

Re: Why is my Autopilot Digital Nano unhappy with pump spefl Is that the 'bypass check valve' that you are referring to (near the cell)?

Re: Why is my Autopilot Digital Nano unhappy with pump spefl Sorry...yes it is 5 psi at 1500rpms. Took return eyeballs off...I was able to go down to 1450rpms (4psi) no lower.

Re: Why is my Autopilot Digital Nano unhappy with pump spefl Psi is still the same as it was with other valve (1000 rpms is 1 psi; 1500 rpms is 1.5 psi) There are 2 returns. The opening looks like 0.5"

Re: Why is my Autopilot Digital Nano unhappy with pump spefl Replaced valve with the Jandy....autopilot still says check flow with anything under 1500 rpms. Any ideas??

Re: Why is my Autopilot Digital Nano unhappy with pump spefl Thanks! Just ordered. Stinks I'm having to pay for this but in the long run it will be much less headache, time and expense should something fail on it.

Re: Why is my Autopilot Digital Nano unhappy with pump spefl The check valve that PB brought over says 2". When I look at Jandy site it states 2" x 2.5" or 1.5" x 2" sizes. I'm not sure which one I would need if I ordered. Would it be the 2" x 2.5" if I have 2" plumbing??

Re: Why is my Autopilot Digital Nano unhappy with pump spefl I'm not sure?? I mentioned the Jandy when I brought this issue up. Maybe doesn't have any on hand...I'm tempted to just buy the Jandy one on my own :| Do valve go bad often?

Re: Why is my Autopilot Digital Nano unhappy with pump spefl Saw new check valve part next to equip. Not installed yet. It is a Spears 2" S1520-20 (swing check valve). Found specs online: min. Opening pressure less than 0.5psi, full flow (open) 150 psi, back pressure (closed) 75psi. I...

I don't :(. I will see if I can get PB out to test tomorrow.

New swg pool installed...after week and a half got aquachek7 test strips out to do some testing. I know...I know...I need the better test kits. But right now, this is all I have to work with. I was shocked when I say 0 FC and 0 TC. Asked PB if put stabilizer in. He said no. Calculated how...

Re: Why is my Autopilot Digital Nano unhappy with pump spefl Thank you Mark!!!!!! I just saw that on the lowes' site for the specs that it requires min. 2psi. Oh geez. Just sent an email to the PB to switch this out to something that is more compatible with the system we have. Thanks...
