Cloudy water...test results inside

[lindz18]

Hey guys! First of all I want to say the BBB method has been super easy. 5 mins a day is all it takes to follow this method. Anyways, I have an issue with slightly cloudy water. When I say slightly, I mean shallow end has a small "tinge" to it. Deep end is cloudy, but main drain is still visualized. Not horrible, but it is noticable and guests have mentioned it. I was hoping for some fresh perspective.

pH 7.6
TA 70
FC 9
CC 0
CYA 80 (I am slowly getting there)
CH 40

I do have a "baby blue" liner color and it seems like it makes the water look sub par as well :\

have you tried adding a little DE to your filter? There is an article about it in the Pool School area.

Okay Lindz ... hi! Your numbers aren't too bad really. The only thing that concerns me is keeping-up with the CYA of 80. So while you are at the target level of 9 right now, if your water ever dropped below that in this heat it may have picked-up some algae.....maybe. With a hint of cloudiness, you could increase your FC a bit more for a couple days to see if that helps. While increased you could also do an overnight FC test (OCLT) to see if you are losing more than 1 ppm of FC during dark hours. If you do lose more than 1 ppm, you might very-well need to just SLAM while it's early. Get it done quicker.

Yea, my cya is a well-known issue to most on this forum. Hee hee. I started out with a cya well over 200. What is de? One thing I have thought of is there is a Nature 2 cartridge inline currently. It was from the prev owners. We have just left that cartridge in (well over expired) so we wouldnt have a leak. Wonder if it could be causing a problem

DE is diatomaceous earth, it's used in certain types of filters. Small quantities can make sand filters work extra good.

Here is how to Add DE to a Sand Filter

Still having a little cloudy water issue.
Cya down to 70
FC 8
Ph 7.5-7.8ish kinda in between
Ta 80
CH 40

It isn't bad cloudy because I can see main drain fine. But, I will say overall it has a tinge to it and when you focus on something on the bottom such as the main drain or your foot you can see some cloudiness. I haven't added any DE yet. I just don't feel smart enough to do that kind of stuff. There is an inline Nature2 cartridge that I have left in the line so I wouldn't have to take it out of the line but it hasn't been changed in over a year.

Take it to shock level to match your CYA. I had the same issue with mines.

How long did you keep it at shock level?

Whenever you have to SLAM like you are supposed to be doing now, you do so until:
1. Water is clear
2. You do not lose any more than 1ppm of FC overnight (that's the OCLT)
3. CC (Combined Chlorine) is <.5
** You MUST meet ALL 3 items above to properly do a SLAM. Simply “spiking" the FC higher than normal isn't SLAMming, therefore there’s a good chance your algae will return.
But there's one problem .... you're not at your SLAM/Shock level. With a CYA of 70, your FC should be at 28. So you might want to add some bleach and "Maintain" the FC at level until you pass all 3 items above. Good luck!

I'm still at SLAM level until my water gets clear.
