Opened the pool 2 weeks ago and have it clear and not using more than 1 ppm of chlorine overnight . Did a CYA test and it’s gotta be 10 or so. The weather won’t be good enuff to use it for another week or 10 days . Wondering if we should run pucks for a week , or throw some cya powder in the sock and try and bring it up ?
Very low CYA , can we just use pucks until it raises then switch back to liquid chlorine ?

Personally, I'd sock it.
Too hard to control FC to stay in range. Always follow this either way you go: FC/CYA Levels

I do this every year and when CYA hits 70 turn the SWG on. The Pool Math "effects of adding" is pretty accurate for CYA increase. A down side is that pucks are more expensive than CYA last time I looked.

trichlor is also acidic- this can bite you if you’re not careful about monitoring ph & ta.
Its fine to use them just beware of all the effects which you may or may not need.
For more than just a little cya bump I prefer to just use dry stabilizer. As mentioned above it is also cheaper.

Dang it …. I knew I screwed up . I thought since no one is swimming in it for a week or so and the chlorine levels are good , I could run 2 pucks ever couple days and raise it. Just bought a $60 bucket of pucks on Sunday and already opened it

Here’s what each dissolved puck will do (if 8oz.)
It will take a while to get up to swcg cya levels
Use the rest for vacations. They will last forever if kept dry
Thanks so much everyone , I’ll just sock it to the pool . And ask my neighbor if they want to buy the bucket. I shoulda asked before I bought .

Yeah for my pool this is another plus along with saving SWG cell hours. Once I turn the SWG on, I need to add acid every 7 to 14 days. With pucks in a floater, it just glides along from November through April.
I just tested with my Taylor Kit and since yesterday we added 2 jugs liquid chlorine since the chlorine was at 2.8ppm.
After 24 hours of 2 pucks ,2 jugs , the chlorine has raised to 5 ppm . TC is basically nothing. The PH is 7.8 and the TA is still at a 100.
FC-5
TA- .5-1 ppm
PH 7.6-7.8
TA 100

I’m the opposite- my ph is usually rock solid. I got my ta down to 60 right after i filled the pool in April of 2019 and it hasn’t budged. Tabs throw a wrench in that stability so I have to be careful with them.
When my previous swcg’s were undersized I would use them in the dog days of summer to supplement fc and replenish cya a little but they bit me and I had to add soda for the first time ever. Thankfully I caught it but lesson learned!
The cost is null to me due to someone gifting me a huge bucket of them that will probably last me a lifetime.
