Free Chlorine Reading Zilch

[Timmy]

Glad I found this thread. I have opened my 30k gallon IG for 7 years now to crystal clear water (use a solid cover). This year, a cloudy mess with zero FC. I shocked with bleach yesterday and tested later in the day, .5 FC. Then I found this thread. Been hitting it all day today and also tested for CYA, that too was 0. I am starting to see the bottom of the pool more than before, but there is nasty looking white crap floating all in the pool now (I suppose this is the algae the FC is fighting?). In turn I backwashed twice today since pressure kept rising. I think tomorrow I am going to disconnect the filter and hose the inside out to clean that crap out (looks like boogers). Will keep hitting it with bleach tomorrow as well. I really want to put my solar cover on to help reduce the sun from killing the FC, but not sure it that will make things worse since the floating crap will end up on the cover and cause issues later.

Hi Timmy,
Glad it's helping but if you want comments and advice, we'd like you to start your own thread--easier for us to remember who we told to do what ...("You told that guy with the inflatable pool to scrub his wall with a METAL BRUSH?????")

Understood. My apologies to the OP, didn't mean to hijack.

That's ok. We'll look for your new thread and help you out there.
