I had similar CYA levels last year and ended up dumping about 20% for my pool (1500 gallons) then refilling it. Repeated this for about 5 times, maybe more don't remember. I didn't want to do more than 20% to protect the liner a little bit from the sun. Was able to get it down to 30 CYA after...

Got it. I was mainly trying to ask what sort of situation can I use it in. From reading here you never really use it since it's about keeping up with FC using LC. For example, can I use every every so often to replace LC just to use it?

They got me to buy the 12 pack powder power plus shock , or cal hypo 73%, for a whopping 100$ before finding this site 3 weeks ago and now I went back to return and they dont accept it. Sigh. Anyways I need to find a way to use it if it's even worth it. I'm doubtful and I'm thinking of calling...

Good morning all. OCLT concluded in almost almost no loss. I may need to do it against to verify on the 0.2 scale. Last night FC 19 and now is 18.5 Cc was 0.5 seeing how my CYA I'd a little low, can I add some to prevent some of the chlorine from burning off so fast? I had some leftover...

FC stayed high at 19 overnight and it looks clearer. Will continue SLAMing until 3 conditions are met. Will plan to do OCLT tonight. Before testing it at night, do I add the target FC slam level or leave as is and just take note of the reading and compare to the morning reading? Also, what...

This is what i have now. FC 11.5 CC 0. Did not turn Pink on first drop Ph 7.4 Ta 90 Ch 230 Cya 30. Rounded since it was overflowing the measuring vial which is around ~25. https://troublefreepool.com/mypool/g6rQlkY Continuing slam process. Really excited to see how far its come. Looking...

I didnt exactly do the OCLT, but had a reading of 21 FC in the morning so thats a big sign of no loss. Also pool is getting more clear.

I'm a new guy here and started by getting a test kit that's recommended and following the SLAM process. SLAM - Shock Level and Maintain

Just got home and pool starting to clear up. See the images, we can start to see the floor now. Will continue SLAM and do the OCLT tonight to see if it can hold. Going to have to read on how to do that. I'm amazed on the results of TFP.

I'll backwash once I get home ,thanks. I bought a new hayward top valve and it came with a new gauge so I'm going to rule that out. The sight glass is clear and with a little bit of sand. When I had the algae bloom 3 weeks ago I did do backwash often and it was coming out green.

Man this pool is eating up a lot of the chlorine. Had to buy 8 more gallons. Still cloudy blue. Hopefully soon I start seeing the light at the end of the tunnel. 🤞

Understood. Today was the first morning the FC stayed over 18 from last night. That's promising right? 🤞😲🤞

Sunday update: at 9am, 12 pm, and just now 6 pm had FC of 12 approx. Each time adding to SLAM level. I may need to go buy more gallons of this stuff. pool still looks the same. Were getting really high heat during the day so is it recommended to increase liquid chlorine to offset that...

The filter is doing okay by the looks of it. Its at a steady 9 psi for the past week, that's its usual working psi. I will be doing a full brushing today , last maintenance was 2 days ago and it was full brushing and vacuuming. Will be checking water chemistry soon and adding more LC per SLAM...

Daily update. At 9 a.m. was 10 FC so added 90oz to get to 20 At 12 pm was 13 FC so added 100oz . A little extra since I wasnt going to be home. At 9pm was at 8 FC so Added a whole gallon for overnight. Water still cloudy blue, but continuing slam.

That's awesome. I will do that, cheers.

Good morning , hope yall have a good weekend and I appreciate all the help I can get. Have family over next weekend hopefully its safe to swim by then. Fingers crossed. 🤞 Tested this morning and FC at 10.6 CC at 0.6. Cya at 45 Going to add LC to new target slam level of 20. My cya raised from...

This is what I have right bow before SLAMing Cc 0.6 Ph 7.2 Fc 6.8 I will be skipping the OCLT as suggested. Will post an update In the morning.

I will start the SLAM process right away since I had bought 6 gallons just in case today. going to test the PH make sure stays at 7.2 or near. At 40 cya, 7500 gallon pool, pool math recommends 16 FC for SLAM target level which is around 73 oz and double that is 140 which is a gallon and little...

That looks really good. How long did it take you to get from cloudy blue to clear like on the last picture?
