Cloudy water after filter change

UPDATE:

Water looks amazing...crystal clear!! I am still losing FC overnight, but all of my readings for CC have been at or below 1. My last test at 10:30 last night showed FC 10.5 and CC at 1. Here are my results from 5:45 this morning.

FC: 3
CC: 0.5
pH: 7.6
Alk: 85

I do have one question. I am going to continue to shock until I can hold FC overnight, but should I start using Dichlor to raise my CYA levels?? They are at zero and I am concerned about have NO chlorine in the pool during the day. Using the Pool Calculator, I could use 5lbs of Dichlor and bring my FC into my 12-15ppm range while also introducing 11ppm of CYA. Obviously, I would watch these levels with a target of about 30ppm(??). Once I hit those levels, I could switch back to liquid chlorine if necessary. Anything wrong with this strategy??

Thanks,
Jim

You can use dichlor but just be aware that as the CYA level comes up, so does the needed shock level to kill whatever is in your pool. If you haven't already done so, please read the Best Guess Chlorine Chart in my signature. I would also suggest a CYA level of around 50 as opposed to 30. (Actually, maybe aim for 40-45ppm and that way if you overshoot a little, you'll still be ok.)

Great. Thx!

Also, forgot to add that you'll also need to watch your pH as well. Dichlor (and trichlor for that matter) are both acidic and will drive the pH down.

Hi Jim;

Here are some things that may help:

1. Link to the chlorine demand bucket test -- it will allow you to estimate how much further you have to go.

2. Links to our online pool history chart -- if you add the data, I'll turn on the graphing:
