I would continue with that so long as the timing is doable regarding your availability to backwash.
If you're done with the SLAM Process, once per day is fine. You just want to raise the level high enough in the evening that you finish the day above the minimum specified on the FC/CYA Levels for your CYA level. This time of year, a daily 4ppm loss is not uncommon.Just testing now:
FC 3 ( I've been checking and adding liquid chlorine each evening. Should I add LC during the day too? )
No and No. Any pH between 7-8 is fine. TA isn't something you need to chase a specific number for. If your TA is high, your pH will tend to naturally rise faster. When your pH rises to 8, you'll add muratic acid to bring it down. That will also lower TA some. Over time, the TA and pH levels will reach a type of equilibrium and you won't need to lower as frequently.pH 7.5 ( Should I raise? )
TA 90 ( Should I lower? )
For a vinyl pool, no minimum level is needed. Too high can cause problems, but too low cannot. It's fine where it is.CH 150 ( I did add about 25 lbs. of calcium chloride Monday, even though its a vinyl liner. What's my CH goal? )
30-40. And we always round up, so you were at 30 prior to adding. Assume the amount you just added is in the water now, and measure again in a few days to confirm the level. Make sure to follow the FC/CYA Levels for your new CYA level.CYA 30 ( It was a bit over halfway between 20 and 30 .... so I've just put some stabilizer in a sock to raise a bit. What's my CYA goal? )
Yes, good to check the result 15-30 minutes after adding FC to make sure it's rising. However, maintaining FC wasn't a problem a month ago before vacation so I don't suspect ammonia, but FC disappearing quickly can't be denied. Likely just the algae which presented due to vacation "downtime" for the pool.I'm a little late to this so take this with a grain of salt. Will your pool hold FC at all? I.E. add your LC, let it mix for say 15 min or so, test, wait another 15 min or so and test again. Did you measure any FC? If your FC disappears immediately than you have ammonia. If this is the case you will need to continue to add LC until you see the level hold. Don't add any more CYA since the bacteria that creates the ammonia feeds on the CYA. You have to neutralize the ammonia with lots of LC first.
If your pool holds FC than the CYA you added just hasn't been there long enough to show up on the test. It can take a couple of days.
