Not likely- the niche & the ladder are prime suspects as @Newdude said.Some bugs and a couple leaves found their way into the skimmer last night. They're organic contaminants... Would that cause a failing OCLT given its sensitivity?
I’m almost think you’ve been making this problem up so you could post a picture of that awesome scenery in the backyard.Failed the OCLT...
16 ppm at 9:00pm
14 ppm at 5:00am.
CC=0
I definitely feel as if I'm feeding chlorine to the sun...
Here is what the light looked like when taking the tests:
Night (sunset at 8:32, test at 9p)

Maybe scoop some of the black stuff out and drop it in a cup of chlorinating liquid to see if it gets lighter and dies over time. It may be algae.Thanks Bperry! I do love our paradise in the backyard!
Update: I drained the ladder and a whole ton of stuff came out. I'd describe it as if the people who opened the pool must have put a half bag of dichlor or cal-hypo down each side. (Maybe not a bad idea??)
I'm convinced I'll need to open up the niche at the next opportunity.
Also, there was this black gooey crud at the water line in the skimmers this morning... Any idea what that could be? Just want to make sure the high chlorine levels aren't taking off a protective film from the liner or something... (The brown discoloration below the water line is from the high alkalinity fill water from the well)

When it comes to algae you must declare war to eradicate it - looks like you’ve won 1 battle, now on to the light niche!
Is that black goo in the skimmer gone? I’d for sure clean that out.What else can I do? Just gotta keep plugging.
Seems like a setback today though... Still failed the OCLT. (17 --> 13.5) (could be because we FINALLY got a half inch of rain?) Plus Ace Hardware ended their $3 sale on 10% bleach.
Sigh. It's no fun to SLAM for three weeks, but I guess I'm still going...
I'm not down though... The crystal clear pool looks beautiful!
Time to check WalMart prices...

It does seem like it was algae... I soaked the brush in chlorine and it did get lighter over time.Is that black goo in the skimmer gone? I’d for sure clean that out.
Usually just once for the ladder. You got rid of the old hidden stuff and replaced it with highly treated SLAM water. For the light it is best to leave it on the deck for the duration so the niche gets good and SLAMMED. Make sure to disable the power to the light though so it doesn’t get accidentally turned on. They need the water to stay cool / not blow.Something's going on... Hopefully the chlorine will get it eventually. Do you guys dump the ladder rails and remove the light to brush every day
Will do.For the light it is best to leave it on the deck for the duration so the niche gets good and SLAMMED.
