If your CYA is at least 100, your minimum FC is 8. Letting it get below that is just asking for problems. You may need to SLAM and then try and keep your FC above 8.

I found the SDS for the Pool Mate Black Algaecide on Home Depot's website. It's odd the manufacturer does not have this information on their website. The SDS does not give more information other than what's on the label, so we don't know what the "other ingredients" are. But the main...

I actually wouldn't put any CYA in at this point. You do not know if you have bacteria in your water that could consume the CYA you would be adding which would lead to a really large chlorine demand. Also, you said you had dumped in super shock and algaecide. Do you know how much you added...

What are you using to test your water? Saying 3-5 ppm sounds like the results from a test strip.

That's normal. You have cold groundwater (well) plus humid air which equals condensation on the pipes. Same as you would would get on the outside of a glass of ice water.

Just a question. When adding your chlorine to get to the SLAM level and performing the OCLT, are you testing again after the addition or just the following morning? Reading your posts, it seems like you test and add to get to the target and that's it until the next day. Maybe you're not really...

You used 200 drops performing the DPD chlorine test? When you added the DPD powder to your water sample, did it turn purple at all?

I do what you do when I close - drain water below skimmer, inflate pillow, cover and use the ratchet the cable around the pool. However, I do periodically drain the water that collects on the cover around the pillow.

I swam yesterday (Sunday) in NJ. The water was 72, which is surprising this time of year. A little brisk but refreshing.

I use a similar foreign-made pH meter and I find it comparable to the color block test. Sometimes I have trouble distinguishing the different shades of red and the digital meter helps confirm my findings. I do find I have to calibrate it every season though.

I've been having a similar issue with the SLAM target FC. My CYA is 30 and it's saying to go to 16. When I tap the arrow to go back to the apps home screen and then go into the FC and check the SLAM target, it shows 12. One of the updates end of July beginning of August was supposed to have...

Who is "they"?

I'm just curious how you are getting 39 for CYA?

Hi nearby neighbor! I also started getting my liquid chlorine at Ocean State Job Lot. I think the closest one is in South Plainfield in the Middlesex Mall. Cheapest price and fresh!

I think @bjsbuds is shocking for mustard algae. That would explain the 24 ppm.
