after 2 bottles of chlorine FC is at 56. Didnt mean to go so high but hopefully this will kill the cc=.25 that is making the pool green. How many days should I keep it at 31?

ok got it up to FC=31 today! Will monitor in 4 hrs! Still green as can be but time to trust in the process!!! Thanks to all for continually supporting my questions and learning!!! Good thing is cc went down from .5 to .25...

ok, after the muriatic PH was down to 7.5. So I started the SLAM process. With CYA at 80 it says I need 24 FC. I have raised FC up to 21 so far, but ph is now back up to "red" region - e.g. greater than 8.2. Should I use muriatic while SLAMming? Or disregard PH entirely until FC is at 24...

Thanks, FC = 6.5, cc = 0 now. Just put 32 oz muriatic and circulating, will check PH tonight, thanks for your help.

ok: FC = 9.5, cc = 0.5! ph is red-orange, seems off the top of my ph scale that tops out at 8.2 with a pinkish color. Estimate at 8.5 maybe? do you suggest adding acid ?

ok - FC 16, cc = 0.25. Seems like it goes down FC 3-4 per day? I can see it clearing up a bit even though it is still murky.

ok, this morning FC = 25, CC = 0.5. I am encouraged about the CC going down!!!

Thanks, yes they were trichlor tabs. FC is now down to 23. I'll sit tight a few days!

Ok checked today...FC at 35 (yikes!) CC at 1.0. Took the chlorinator out as one had suggested. PH still "red" - unable to tell how much higher than 8.2 it is. Should I add more muriatic to bring down the PH say 0.3-04?? Or just brush the pool and wait a day?

Thanks all for replies! Read the SLAM documentation and it looks like I first need to wait until PH is 7.2-7.5. So I should check the FC 1-2 times per day and wait until below 10, then adjust PH?

Hi, pool has gotten super murky/cloudy with the temperatures dropping. All other parameters are good: TA = 100 CYA = 60 FC = 30 / CC = 1.5 CH = 250 PH I can't tell - on the little plastic reader it shows up "reddish" which makes me think it is higher than 8.2, definitely not on the 'yellow'...

I was referring to swapping the dirty ones with brand new 520's. Over the years by power washing the 420's the bands have mostly busted. I havent found a quick way to clean between the pleats. But at $180 for a new set...if they hold up a while, I'm seriously rethinking the labor to clean vs...

Hi, My heater which is about 20 years old just wouldnt turn on. Pool guy said it was the board, board is $150 and labor so total of $300. He said alternatively he could get me a 5 year old heater, same style, from someone that was upgrading, for $800. Any ideas if this is a good strategy?

The 520 is about 8-10 inches taller than the 420. The other dimensions are the same. So basically when I was using 420's in my new filter (designed for a 520) the top 1/3 of the filter dome was not holding filter. The 520 takes up the entire room within the filter. I am hoping it will give me...

Great info! thanks! Thanks for the info! I was not completely clear in my filter upgrade. My old filter used 420's. When I upgraded to a new one, it was larger, and was designed for 520's but could run 420's (because I am cheap and wanted to reuse my old 420's that were in ok shape)...
