Algae cannot live in absence of light, so no. But it is bacteria or other life form that gets hold when you don't keep your FC up for your CYA.

Do we think this green is algae?

So it’s not algae? I’ve kept my FC up
To CYA levels for 12 days.

It, like algae has a biofilm. Brushing and scrubbing breaks the biofilm allowing the HOCl to kill it. That's why we scrub inside ladders, behind lights etc.

Should I also give the DE a whirl. Just arrived from Amazon. Supposed to be having a pool
Party tomorrow

Go for it.

Backwash. Add DE. Note filter pressure. When pressure rises 25%, repeat the process.

On the SLAM side, check and replace every 2 hour, will speed things along.

If you cannot see the bottom of the deep end, it is NOT safe to swim.

OK to swim if FC is between min up to and including SLAM levels.

If I’m using the instructions on TFP it says to start with .25 cups. It looks like it’s 10:1 water to powder. So 2.5 cups water to .25 powder. Does that sound right?

 

[PoolStored]

Yep

 

[Djuke1210]

No need. Periodically checking the CYA is a good idea, but other than that, maintain the proper FC level and continue with the sweeping & brushing.

For what it’s worth, AK is testing at 50.

Here is the guide to follow:

Add DE to a Sand Filter

A clean pool filter will increase the efficiency of your pool! ... your filter are to backwash it, clean the manifolds and grids, and add new DE.

No change overnight. Only lost .5 FC. Haven’t tried the DE yet. Was hoping cleaning the ladder would have led to some big improvement.

 

[Djuke1210]

Ok what should I be trying now.

 

[PoolStored]

Try the DE. Sand filters just take time. That looks like mine did when I found the ladder, took a couple more days. The ladder solved your OCLT!

We really hadn’t been losing fc overnight to begin with. We used DE this am.

 

[Djuke1210]

starting week 3 of slam still milky blue and can’t see the bottom of the deep end. Should I increase chorine levels? Try something behind liquid chlorine. Something doesn’t seem to add up. It’s been stuck in this state for days.

How did you perform the cya test? In your words.

Fill the small tube up to 7 and adding the reagent to 14. Shake for 30. Pour in the tube until i can’t see the black dot. Just under the 40 mark so im rounding up to 40.

 

[Djuke1210]

Wonder if i should bring to a pool store to see if my numbers are way off?

NOOOOO. 40 is great from your own testing. PoolStore testing is unreliable.
