Ed here. I'll ask my question first and then give some back ground as I want to share some info and a few lessons so far.
QUESTION: I am at stage 2 of Baquacil to chlorine conversion process ie CYA 30, FC 15ppm and keeping CC<.5 for 2 days. Do I need to get my CYA down to 30 pronto or can I wait for it to maybe go down with some rain we are due to get today?? CYA: 50 and has been 50 for past 12 hours, FC: 15ppm, CC's: .5 PH: 7.4-7.6

Been reading on this site for 6 months now. Great Info! Thank you all TFP and especially ssJody and his conversion thread. So Iam at Day 6 of my conversion and at stage 2 where I am holding FC at 15, CYA at 30 and no more that .5 CC's and wanted to share some info.
Starting last year I quit adding any Baquacil about a month prior to closing pool. During winter I covered pool and drained all rain water into pool(and of course drained pool when water got to high). I used a few old RV water filters at end of drain hose to keep dirt and junk out. This made draining cover take longer but worth it I think(last month of draining was the "pollening" season here). I calculated I drained about 3 feet of water into pool over winter.
Opened up pool 2 weeks ago and it was a little green and mostly just cloudy. Notice yellowish film on sides and bottom so decided to brush and vacuum to waste. Our water here is not that expensive and the water company here is good about filling pools and will not charge you the sewer fee if you call them and tell them how many days you will be filling pool so did that. I calculated another 2 feet of water doing this vacuuming to waste. With this complete decided to go for it and not replace water using tarp method. I used some left over Baqucil test strip and they showed no Oxidizer. AHHH well it really showed low oxidizer and there is no test for the CDX(I did have Baqucil and maybe cdx still left in there as my conversion proved).
Day 1 started the conversion using TFP pool school Baquacil to Chlorine conversion process. Started with 10 gallons of Pool Essentials Chlorinating Liquid from WALMART($3.47 a gallon) Ha! not nearly enough and was back on day 2 getting 10 more.
Day 2- 4 Adding chlorine checking FC levels scooping leaves. SUN EATS CHLORINE almost as fast as you can add it. In hindsight I think I should have put pool cover back on for these days. I read some threads where yall suggested that with some people. anyway was really concentrating on overnight loss of FC.
Morning Day 5 No overnight loss of FC, maybe 1, but I declared victory and am now on to stage 2.
Day 5 Changed out sand filter. UGH!! What a pain and it always has been(PS Iam in my early 60s and its different now than 15 years ago when I first started all this pool maintenance, Ha!). Added CYA using sock method and put it my filter basket for about an hour. Then I sat and squeezed the sock for about 30 more minutes. Would have LOVED to have some liquid CYA at this point cause I was beat just from the sand filter change out. But I realize from more TFP threads this is the best way for adding CYA. So I waited another hour for stuff to circulate and tested for CYA. It came up around 30 - 40. That dang dot test is a bit tricky. FC was a little low at 8 ppm ie sun had been up for 3 hours. Added Chlorine to fix that.
Evening Day 5 CYA now shows 50(did 2 tests to make sure) FC a little low again so added Chlorine. CC: <.5
Morning Day 6 before sun up CYA still at 50, Chlorine solid at 15 ppm, CC: <.5

So above pics are of the Chlorine I got from WALMART, Pre Day 1, Day 1 of adding Chlorine and now Day 5
What a transformation I will attest Baquacil never got my pool this clear. I now know the definition of a sparkling clear pool! For Maddie of Yippie Skippy I did not get the 70's acid trip but it was a wild flourescent green for about a day.
 
I think u have made it through the fire so to speak.
If u are holding chlorine you should be ok-
@Leebo may have better insight for u.

Sorry to hear that. Would you say the water was usually cloudy all the time you used Baqua? While still encountering some problems, I must say that I've been really pleased with water clarity - assuming everything is in balance and sufficient oxidizer level. If I wind up converting, it'll be interesting to compare.

Well.....this swimming season might be a bit of a blowout. I might be going in for rotator cuff surgery. Was doing really heavy pruning of dead branches, etc. on mature shrubbery and that evening started to feel severe pain in the arm and shoulder. I have very limited use of the right arm. If worse case scenario comes to pass (the surgery and required recovery time), it won't be me that'll be opening the pool - let alone worry about converting to some different chemical procedure. Fingers crossed that it's just an aggravation of a very similar (though not near as painful or debilitating) issue I had last summer from overdoing the swimming. I had therapy for shoulder impingement last fall...and back therapy for the fractured disc also. This 'getting older' is not for the squeamish. I'll know more after an appointment with an orthopedic specialist next week. Summer = worse possible time to not have full use of both arms.

Man, sorry to hear.

Congrats on your conversion!! Now when are you adding that SWG? 😬
OK starting the process of the SWG today but I found I have to get the calcium hardness up. I am at 100 right now so looking to get to 250. Bag directions say if I need to add 10 lbs I should only add 3.3 lbs every 6 hours. Any idea why this is, unless you might want to test each time so you dont add too much?
Also my plan is to add required salt, run for 24-48 hrs, then plumb in SWG. Have all the tools and equipment and good area for install so shouldnt be too hard......yeah how many times have I started a project saying that phrase ;(
Question Do I need to put the SWG on a timer?? My pump is on a timer but I was planning on just letting the SWG stay on. As I understand It doesnt try to produce chlorine unless there is water flowing through it?

The clarity is hard to explain with Baquacil yes i had periods of cloudy but then I could get it to clear up. BUT when making this conversion and getting it cleared up the water just sparkled. Even my daughters said Dad the water looks so much more shiny and sparkles more. Once you switch you will notice it.

That's not just baqua but even switching from the typical pool store style chlorine to TFPC is incredibly noticeable after the switch. Right now my pool is cloudy from opening, but you can see the bottom just fine and there's a bit of a shimmer when the sun hits it. Years ago I might have considered it acceptable, now I know it's still got quite a bit of filtering left to do. Be warned that TFPC turns you in to a bit of a pool snob. My wife has seen pictures on friends' FB of "yay, first pool party of the season" and recoiled in horror at the water they are proudly displaying :LOL:

Yes u need the swg on a timer. You can possibly use the one u already have for the pump.
The flow switch shouldn’t be the primary thing that turns the swg off/on as they can fail.
pics of your set up can help everyone give u the correct advice on this.
 
OK so did a salt test today before adding salt. Wow I am already at 1400ppm, is that normal?? Baquacil to chlorine conversion complete. Chemicals are as follows.
FC = 4
PH = 7.4-7.5
TA = 60
CYA = 60
CH = 300
I have been adding Calcium Hardness Increaser the past 3 days to bring CH up, 20 Lbs so far, could that be a reason? I am on city water.

Awesome. I'm only on day 3 of my conversation. Finally seeing the bottom of the pool again.
 
Could it have been a chlorine pool before the baqua? The bleach you have recently added contributed a few hundred ppm.
