Chlorine

[Russo221]

Ok have a question. I wake up at 6 a.m. everyday test the chlorine level and after put in the necessary amount to get it to the level it needs to be. My question is is it better to put in the chlorine at night? Or is it better to put it in like I have been doing in the morning? I put in liquid chlorine so you know

221,

In my mind the key is to make sure the FC never goes below the minimum. So, no matter what time you add it, if you test again in 24 hours and your FC is not below your minimum, then you are good. I don't believe it makes much difference when you add it..

Thanks,

Jim R.

Ok my cya level is 50 so my chlorine level is between 6-8. So in the morning I get it 8 and when I check it again at 6 am it's around 4 or 5 then I get it 8 again. Is that bad if I test it in the morning and it is low like that?

Look at the FC/CYA Levels for a CYA level of 50.

 

[Russo221]

I know what the the level is supposed to be. Cya level is 50 the FC level is 6ppm to 8ppm. So when I put the chlorine at 6am it's at 8 and then when I test it at 6am the next morning it's arrive 5ppm. My question is is that bad cause it's below the minimum when I check it in the morning?

If the FC is below the minimum for your CYA at any time that is not good. You need to add more liquid chlorine to be sure that does not happen.

Ah ok, I see what you mean. So I might as well put chlorine at night too so when I wake up it won't be below 6. Question tho, if I put more in at night the filter is not on. How long do I have to run the filter before I can shut it off after adding the chlorine

 

[mknauss]

You should be able to add enough at one time each day such that you do not go below minimum until you add again the next day. If not, something is not right.

It is recommended that chemicals be added with the pump running. The pump should be run for 30 minutes after any chemical addition.

your minimum is 4ppm with a 50 cya

I add at night. That way if anything is growing, the chlorine is not competing with the sun n killing what it needs to. I also run my pump at night.

I also test and add at night. well as the sun is close to down. Give the added FC time to do its thing without competing with the sun like Casey said.

When adding chlorine (especially when adding only once per day), you can go over your target a bit to ensure you never drop below minumum FC for your CYA level.
