I'll let it drift back down to normal SLAM levels and see how much I lose overnight, but I'm certain the algae will begin to bloom again and get much worse. It's hard to tell in the photo, but in person, it's much more visible. This is the bottom of the deep end currently, which is the least...

I'm aware that below 20ppm CYA is hard to measure, but why should I bring that up while SLAMing? Shouldn't I wait until SLAM is complete? And I started with SLAM at recommended levels for a week, then raised to mustard levels, but it kept growing, only after raising much higher am I seeing the...

I lose about 7fc overnight. I know the sun bakes off most during the day.

I've been using TFP method for 6 years now, with great results, and every year I fight against mustard Algae, but this year I'm stuck and not sure what else to do. I opened my vinyl in ground pool on March 25th balanced the chemistry (7.2ph, 80ta, 20cyn), then SLAM'd and brushed 3x per day for...

The pool has now passed all 3 slam criteria and the chlorine is back to normal levels. The water is perfectly balanced and crystal clear. I swam to the bottom of the deep end to inspect the drain, no sign of any mustard algae there, so I think I’m good to go. The moral of the story for me was...

Ok, I think I found where the MA was hiding. I always remove the light and scrub the inside of the niche, but just to be extra thorough, I thought I’d try to clean the inside of the conduit that carries the wiring for the light. I used an air compressor to blow air from the electrical junction...

The poofing never fully goes away, it’s just less with more chlorine. It will pass OCLT, then brush right after test at sunrise, and “poof”.

@Texas Splash I’ll take a look at the drain, that’s a good thought.

I don’t take it as an insult at all! I just wanna get this taken care of. At chlorine levels under 10ppm, the water starts to look a little cloudy and dull, the walls and floor look dirty, when I brush any surface a brown/yellowish cloud appears, almost like sand, but it’s not sand. When at...

Yes, I know MA level should be for 24 hours, but after going through this process 3 times and the mustard algae still returning, I went twice as long this last time in case that helped. My sand filter is 2 years old, I will be replacing the sand this week while filing the pool. I should also...

Yes, the pool is surrounded by acres of Forrest. When I scrub the walls (not floor), clouds of yellow / brown material bloom the the water, and if the chlorine is at non slam levels the water gets murky and dark cloudy, it doesn’t seem to be only pollen from what I understand. The weird thing...

Well it's filling up now, so I won't test and balance until it's filled back up. Here is a current picture of it filling back up. But before draining I was at: FC: 26ppm (4 sunny days drifting back down from a mustard algae level of 33ppm) PH: 7.4 TA: 70 CYA: 55 TEMP: 75 F SALT: 3550 CH: 67...

I posted about this issue a few weeks ago, but here's a quick recap. I'm dealing with a mustard algae problem that I can't seem to solve. Last month, I SLAM'd the pool for 2 weeks until it passed the Overnight Chlorine test, then brought the chlorine up to Mustard Algae levels for 48 hours. I...

Almost half of the summer in 2023 was spent with chlorine levels too high to even use the pool while trying to continue to get rid of the mustard algae. I'm trying to avoid that this year.

I would SLAM by maintaining FC of 24ppm (CYA = 60), brushing every surface 2x daily and would maintain 35ppm until it passed the overnight test (no change from sunset to sunrise in FC levels), then would raise it to Mustard Algae shock level, in my case 35ppm. And yes, I'm aware that I'd be...

First off, I want to say this site has been a godsend. I've been using what I've learned here for the last 5 years, and my pool has been perfect with minimal effort and expenses. (I've only had to step foot in a pool store once to buy a fitting for my pump.) Last summer, I developed a mustard...

My wife and I were out of town this weekend and it rained 7 inches in one day while we were gone. By the time I had a neighbor come drain off the extra water it was too late, the water had already risen above the liner. Now there are wrinkles and clearly there is some water behind the liner...

First off I wan to say thank you to you all, this is my first year owning a pool and this site has been a lifesaver! Ok so we're about to close the pool for the winter, I think I understand everything I need to do, but I do have a question... In addition to my main pump there seems to be an...

Thanks @Mr Bruce! I'll keep SLAMMING then! And yeah that's a good call, I'll try that next time. Thanks!

Ok so I've passed the OCLT and water is perfectly clear in the shallow end and just a touch cloudy in the deep end. I'm new to owning and maintaining a pool so I'm not sure how clear it should be in the deep end (8ft deep). Here are pics, what do you guys think?

Thanks @critter783, yeah I saw that too but most we out of stock when I got there I finally found one that had some so I loaded up and got 10 more boxes.

Ok so I bought chlorine at the only store that had any in stock (a Lowe’s 30 miles from my house), but after testing I saw that it wasn’t working, I looked at the bottles and saw that they’re manufactured in 2016. I’m so close to finishing the slam but I’m not sure what to do other than buy 6%...

I can finally see the bottom of the deep end clearly! I'm literally having to drive all over town to find liquid chlorine now, I've bought up everything from my local Home Depot, Lowes and Walmart stores, and it looks as thought none of them will be stocking up on more since it's late in the...

Thanks guys! I tested the CYA today and it's either 30 or just under (it's hard to tell)
