Dirty water but no CC

[mjnorman]

Hi all. Been with tfp for a while now, but this one is throwing me for a loop. I have had dirty looking water for a couple weeks. There is dirty junk on the bottom of my pool and it definitely has a green tinted. I have posted full readings below, and I don't see how I could have algae blooming since I have no CC? I've also been running swg at 50% and my fc is always around 3 or 4.

I feel like this is more of a filtration problem since the water just looks dirty. Can I be wrong here? I dumped a couple gallons of chlorine liquid I had and bumped swg to 100% ultra hence the large readings below.

Thoughts?

TA 90
Cya 80
Ph 8.2 (keeps drifting up)
Fc 17 (currently have swg on super)
Cc 0
Ch 125

I also forgot to mention I did a 6 hour TSP soak on my cartridge although it wasn't really that bad to begin with.

You need to follow the SLAM Process. Use liquid chlorine.

CC is primarily from ammonia based compounds. Algae does not generate much CC.

If you can see algae, you have algae.

With of CYA of 80, you need to SLAM with FC level of 32.

When the algae is killed and the slam completed, with CYA of 80, your normal daily FC need to remain between 9 and 6.

And here I thought I was going so good

So was this just a result of keeping FC too low and overtime it built up?

After reading the above tfp expert’s opinions, I agree, your FC likely was the biggest issue. Since You cleaned your filter recently, it was just pointed out to me, if any of those white horizontal bands break, it’s time to replace the Filter.
Do you have a good pool cleaner? Important to get that stuff off the bottom as much as you can manage - ideally thru the cleaner because that will save your cartridges that extra load of pool bottom stuff...
