3 Week battle with algae

Finally making some progress

What did you end up with for cya?

Last test showed 50

Last test showed 50

So about a 30% exchange.
Better than before. Less copper is always better. If I did the math right (questionable ) that would make the copper number around 0.35 which is still enough to cause problems but definitely more ideal than 0.5.
A safer bet is 0.2 or less. Definitely looks much better already though.
SLAM ON

Couple of questions. My pool has cleared to the point where I can now see the bottom of the ladder. However I can't clearly see the bottom. Should I continue with slam? Secondly I've been placing polyfill in my skimmer basket daily. It's capturing a light greenish colored "stuff" is this algae? What color would iron be if it's being captured?

Yes - continue until
CC is 0.5 or lower;
Overnight Chlorine Loss Test
AND
The water is clear.
(Crystal Clear w/no algae dead or alive)

Secondly I've been placing polyfill in my skimmer basket daily. It's capturing a light greenish colored "stuff" is this algae? What color would iron be if it's being captured?

Most likely algae - iron would be brown usually.

Polyfill is also generally not capable of capturing copper.

So I’ve learned my lesson using FLOC, but are clarifiers going to coagulate in my sand the same as FlOC did?

They can gum it up if used on a regular basis or in too large of amounts.
The deep clean & DE afterwards is the way to go. Clarifiers are a last resort.

My TA is pretty high. Can I address this now that my SLAM is nearly complete?

My TA is pretty high. Can I address this now that my SLAM is nearly complete?

Not until it’s actually complete. TA is not very important, don’t worry about it until SLAM is done.

My TA is pretty high. Can I address this now that my SLAM is nearly complete?

The ph test is invalid at fc levels over 10ppm so nope , you must wait - also TA is the very last thing one needs to address in the pool. Higher ta doesn’t hurt anything it just leads ph to rise more quickly. You have no recent ta logged in pool math so I’m not sure what you mean by high.
When fc comes down after you’re certain slam is complete here’s the way

Lower Total Alkalinity

A lower Total Alkalinity level can help a pool owner stabalize their pH increase. We'll explain how to lower TA with a little help from muriatic acid.

Just wanted to give an update. Pool is finally clear. Friday and Saturday morning I awoke to a mass of what appeared to be algae in the center of the pool. Vacuumed to waste both days and the pool is clear again.

Thanks to everyone for the support and guidance. I was throwing my hands in the air in frustration on this one.

I wanna see

Now, that's a TFP clear pool.

Congratulations!

Great progress
You wanna be sure you keep with slam level fc until crystal clear like this
How Clear is TFP Clear?
With no more algae (dead or alive) reoccurring ,
you pass an Overnight Chlorine Loss Test,
& cc’s are 0.5 or less.
