I'm sorry if I'm being dense. I understand about keeping on with the SLAM process. What I'm not understanding is how to tell if I'm doing it at the right level? I thought my chlorine would be dropping rapidly during this as it killed algae and I'd have to be adjusting it back up a lot, but the biggest drop was 2.5ppm and that took 36 hours. Maybe that's normal though? I've been believing my CYA was 50 but this has been making me doubt my readings, however I'm out CYA reagent to double check until Weds.
The FC/CYA chart in Pool School tells you how much chlorine to use. Have you seen it? Are you following it?I really don't know if that amount is warranted or if 20 was actually fine.
Yes, I'm trying to follow it. 20ppm was SLAM level based on 50 CYA, when almost nothing was consumed I raised it to 24 based on 60 CYA, but I lost nothing yesterday at that level. Last night I tried 28 based on 70cya. There's no way my CYA is over 70! I'll test this afternoon.The FC/CYA chart in Pool School tells you how much chlorine to use. Have you seen it?

Here are a couple of pictures, taken just now of the pool. Also the filter from this morning. Is that algae? It looks a bit like captured iron but maybe less red and I mostly see that if I put a sock over the return jet, then the filter catches it too. Yesterday's brand new cartridge had none of that. This cartridge from last night is a week old, so maybe the water doesn't flow through it as well?Call your CYA 60, stop being troubled by it, and SLAM your pool by replenishing chlorine to the 24 mark.....it's that simple.....no need for angst.
We would all like these issues with pools to be totally black and white but they are not. assuming 60 for you CYA is just fine.....dose FC to 24.
Could you supply a pic (taken today) of your pool water please? Could you also retest and post
Bazinga! Yes, your pool is less green....making progress.Hmmm, looking back at the picture I posted originally the pool does look less green, but more cloudy now.
Vacuuming and brushing are an essential part of the SLAM. I am a bit surprised you attempted to SLAM without a vacuum but that's water under the bridge. Meanwhile, I see enough from your words and good pictures so no need to re-test but let me say this........It is really essential you get your ducks in a row in order to have a successful SLAM. Not enough reagents and no vacuum make the SLAM almost impossible to complete. Are you running the pump 24/7?I don't have a vacuum yet,
Yay! I'm glad it looks like progress!Bazinga! Yes, your pool is less green....making progress.Vacuuming and brushing are an essential part of the SLAM.

If it was my pool, I would continue to maintain SLAM value chlorine and get a vacuum and get adequate reagents and then start the SLAM again. The SLAM works EVERY single time you follow the SLAM article precisely.
Sorry, was trying to edit to say pump has been going 24/7. Don't know why it did this and I can't delete it.Yay! I'm glad it looks like progress! Yes, pump hasn't been off since I got home from vacation.
I didn't know I was going to have to SLAM. I've only had the pool up for two weeks. I bought the test kit after I was having problems with my well water and iron. Got it clear pretty quick, but had a vacation planned already the weekend after I got it up (I had a neighbor adding chlorine but I just hadn't had time to learn enough yet to have gotten that part right apparently.). I also hadn't had time to find a vacuum that would work with my particular pool from the time I got it up until I had to leave, and didn't want to order additional reagant that might come while I was gone and have it sit in the heat. After I came back I ordered more reagent and a vacuum because I knew I'd need them eventually but they just haven't come yet. I live in the country so running to the pool store for supplies isn't an option. I originally thought the cloudiness was from my iron again like originally but was advised on here after asking about whether I should SLAM because of the 4-5 inches of rainwater I got that I should SLAM because I had algae, so I started it. I'm new to this and didn't realize I could wait until all that stuff came, also didn't know that my chlorine wouldn't be dropping and I'd be using so much reagent for one test! I know there is a lot of information on here, but that's just it. It's a lot all at once when you start with zero knowledge and just because I read it once doesn't mean it sunk in. When I bought the pool I was trying to find information and coming up short, I didn't know what else to do but jump in. It wasn't until I had a very specific problem that I could search that this forum came up and the information started making some sense.
Believe me, if I'd known all this stuff beforehand there is a lot I'd have done differently, starting with not opening my pool right before vacation! It made the week up to that needlessly stressful, got used three times and now I have a new problem, didn't gain any useful time from getting it up sooner but sure gained extra work!
Tested and FC has dropped from 28:Could you supply a pic (taken today) of your pool water please? Could you also retest and post
Homemade filter for the win!Here is a link for a DIY iron filter that works for steel frame pools.
