I scrubbed a number of vitamin c tablets on the walls and it does have an effect. However, no effect on the black spots. That at least gives me hope that my plaster can look less cruddy if I do some ascorbic acid treatment and sequestrant. I will probably get the culator also. Some metal...

I'm getting some vitamin c tablets today to test on the brown area to see if it's metal staining or not. I know it's possible since I used the stain remover stuff, and my filter needed to be changed so I think the metal staining that was removed possibly just got re-deposited.. Though I'm also...

I honestly have no idea. I definitely had black algae on the tile grout, so I suspect it's algae starting on the plaster. Maybe I caught it before it got as big as yours? I've had the chlorine at 20+ since Oct 31. But I don't know. When I brush the spots they get a bit smaller but don't...

Interesting. They are much smaller there than they were because I had already scrubbed them. I just took this photo. That area is the dark spot I've seen, that has some black spots on it, I think... But could just be how it looks in the pic. The other spots have formed around that general area...

Yes they're just like the attached. I scrubbed the new ones and now it's dark so I can't really get new pics yet. These were after I brushed them also, so they were a little bigger. All signs point to black algae because of the chunks I found on the tile grout and turned green when I smooshed...

Thanks! WFH helps the ability to keep up on it more than I normally would be able to! I had a terrible dream last night.. I woke up to images in my head of there being a thick layer of black slime all over the pool! 😬 This morning there was a new black spot on that same wall where most of the...

Great Info... Thank you! I had my SWG on until this afternoon, I had forgotten to turn it off. Should I turn it back on at night to help maintain the SLAM level until I can check it in the morning before work? I think right now I may need to worry more about keeping it at SLAM or + rather than...

Question... Since I had already been gradually increasing my chlorine via my SWG prior to starting SLAM, will it work as intended? I feel like my water is clearer but I also feel like a couple of the spots I posted pics of, have come back after they faded a little from the scrubbing. Or maybe I...

Note to add for future readers: I learned that Hayward advises against lubing the filter head gasket. I also read that can cause it to break down and not seal as well as it should which I thought you lubed to help it seal better. Apparently theirs are engineered in such a way that it's not...

Thanks! Too bad I saw tons of fibers and specks of blue stuff in the filters... Now I'm worried it's from the PVC pipes. Probably from when I used the stain remover and it told me to keep the pH super low 😡 Hopefully that's not what it was, but if it was from the pipes, hopefully it won't be any...

We took everything apart again and put it back together. The o-ring is now showing some metal after cleaning it with a rag so I'm suspecting that's our culprit. And can find one locally. It's dripping a little less now, and no air sounds from the relief valve but I'm going to keep it on low...

Another pic.

I notice a small amount of water coming from the top, which is probably coming from the relief valve. And a small amount dripping down from the side. I did see a tiny slit in the o-ring upon second inspection so it's possible that's the culprit. It's actually coming out the side pretty...

Of course, now that I got the filters changed there is a small amount of air leaking out of the pressure relief valve on the filter, and a small drip coming from where the lid meets bottom. 🤦‍♀️ I took it apart a second time and lubed it again but will do it once more and see if that solves...

Well, I ordered it because that convinced me It's what I need 100% even though I'm skeptical because it's nylon on plaster. I need more omph because I'm weak ☺️

The returns don't break the surface at all. I learned about the aeration increasing pH early on so I made sure of that since I've always had a hard time controlling the pH. I actually run my pump 24/7 on medium and low speed based on a schedule. I raised the TA (and keep it higher) to keep my...

Ohhh! Interesting. That's the opposite of what I've always heard and feel like I have experienced. I notice a vast difference when I use my SWG or have it off. The pH rises FAST when it is on and I have to use acid a lot when it is. When I just use liquid chlorine it rises very, very slowly by...

Thanks! My FC was at 10, 4 days ago and my pH was 7.6. My log shows 8.0 when it was 10 FC, but I added acid right after that test and didn't log the re-test. I've been bad with my logs. I do the testing and adjustments, just haven't been logging them consistently. I also didn't renew the app...

Thanks! I'll have to go get a bunch of liquid chlorine. I think I only have 1 gallon and didn't refill my jugs since the SwG is running again. If I go above the recommend FC level at any point, is that going to mess it up? Also, with my current FC being so high (I was trying to kill the...

Hello.... the perfect storm has occurred and I am now realizing I am starting to have a black algae problem in my pool. I started seeing some black colored build up on some tile grout lines and finally took one chunk off and smeared it onto a towel, which turned green. I noticed a couple of...
