    Deep end cloudy after vacuum

    Here's my backstory. Wednesday afternoon/evening I had the vacuum in the pool (Hayward suction side) for a few hours to clean up some dirt on the bottom. It was dark when I took out the vacuum and turned off the pool for the night. The next morning when I went out the deep end was cloudy (gray/white). Not cloudy enough that I couldn't see the main drain but definitely noticable.

    My wife insisted on taking a sample over to the pool store. Their results were close to mine. They, of course, suggested we buy some "shock" which she got.

    Ran a full set of tests yesterday after work. I didn't put the "shock" in the pool because I don't think I need to shock the pool.

    FC= 3 (put chlorine in for the day to get it back up to around 6.0)
    CC=0
    TC=3
    pH=7.2
    TA=130
    CH=200
    CYA=50 (pool store says 30, I believe the TF100)

    I ran the pump all night. Looks about the same this morning.

    I wonder if my filters need to be cleaned again? I just did it a few weekends ago. The filters are 5 years old too so I wonder if they just need to be totally replaced. Any thoughts would be great. Maybe I just need to be patient and the vacuum kicked up a lot of **** and it needs to just run through the filter.

    Re: Deep end cloudy after vacuum

    I plugged your information into the pool calculator and it looks like your FC levels should be maintained between 4-8 since your cya is at 50, at 3 you're a little low and if you do have some organics in the pool you could quickly see problems. Could be a bit of algae trying to get hold.

    Sometimes when you see something on the bottom, it's just pollen or small debris (we get a lot of tiny tree debris here) and when you brush or swim it stirs it up like a cloud, but that usually settles in a matter of hours even w/the pump running. The filter should pick it up over time if that's what it is, but keep it stirred up so it is easily removed by the filter.

    I would tend to lean toward raising the chlorine up to shock level and see if it passes the overnight chlorine test. Then you know you'll be safe for the weekend.

    Yeah you're right. I must have had 40 CYA in there from before (it saves my last settings usually). Dang it, I'll have to bring it up to shock tonight and check it in the morning.
