Featured Stubborn algae afte SLAM

How high? Just curious.
I run mine between top of the range for my CYA and a couple FC higher. For two reasons. If I get a high demand day (lots of sun/swimmers) I never get below range. I don't like fiddling with output %. I might change it once a week as UV changes. Since it is safe up to SLAM level, I just don't fret being a bit high.

THIS RIGHT HERE!!!
TFP post of the day
Haha! Glad my situation was of benefit :)

Honestly the hardest part was the "pool water is crystal clear with no visible sign of algae (dead or alive)" part as its somewhat subjective. I *thought* the water was crystal clear when I stopped but now that I did it properly I can see the difference.

OK good to know. I'll keep that in mind as I figure out a suitable output for my SWG...

If I keep my FC at 10, or slightly above as suggsted, how am I to check pH to make sure its ok? From previous comments the FC should be below 10 to get a reliable pH score (which I aleady find to be a PITA) with the "match the color" test in my TF-Pro test kit...

You'll get a feel for both the FC and Ph fluctuations over time and test when they are favorable for it.

By running hot it still dips below 10, just, we have tons of room to spare when it does. When the others dip lower than they wanted, they are flirting with Swampville.

Also try 4 drops instead of 5. I will use both sides of the block with one with 4 drops and one with 5 and use whichever one has the right shade for the test. Thats the important part, not the # of drops. If the test is impacted the colors won't line up.
