I opened my filters this morning to look in their again and at the top I found some black crud again. Is that some kind of algae or is it just oils or something? I ended up using Dawn dish soap and a brush to get it off and then put bleach in rinsing after each and got it cleaned out.

My cell is basically new, we have had water in the pool since 4/28. So for the OCGT. Basically if I loose lets say .5ppm of FC during an 8 hour long OCLT and I do an 8 hour long OCGT with my cell at 100% I should expect a net gain in FC of ~3ppm since my cell should generate ~3.5ppm in 8 hours...

Guys I'm back to having issues again. I SLAMed the second time from Aug 25 to Sep 2nd when my OCLT resulted in a .6ppm FC loss. I then proceeded and cleaned the filters on 8/4 and noticed some black crud at the top that I cleaned out and then for good measure raised FC up again and then...

Sounds good and Thanks. Still learning

I just tested CYA and I lost 10ppm(From 60 to 50) from 4 days ago when I tested right before performing the SLAM. Should I continue using the 60ppm of CYA till I am done with the slam or trust the 50 and use that to determine FC level?

You got me looking and I'm thinking I may have found what I overlooked before. I dont think I actually got the SPA main drain flushed during my first SLAM. I just changed valves so its continually pulling/pushing water through all the lines and all the valves. So now I'll just have to make sure...

When I completed the first SLAM I did pass all criteria I had a CC of .2, On my OCLT I lost 0.8FC and in the OCLT doc it says up to a loss of 1 FC, and the water was never green and always crystal clear. Its crystal clean now too. But I still feel I had to have had something left in the pool...

I am also thinking I must not have gotten everything killed the first SLAM. I thought I would be good because the OCLT doc said below a 1ppm loss you pass and then I kept it above an 8.6FC for another day and a half but I also started increasing CYA right after the first OCLT passed.

Yes I am well aware an of 0.6 FC is a problem. It dropped there after the issue started. My SWG was set at 60% which should be more than enough to maintain a FC of 6 or more.

If you don’t want to read a book about how I got here feel free to jump down to “The Problem” section. In short the history is that I had just performed a SLAM and passed an OCLT 13 days ago. The History: Hey guys looking for some help. We’ve had water in our pool for about 90 days and after...

The pool is full. And yes the kids had to put their feet in and unfortunately they drug dirt in with them so hopefully they come out with some brushing. Right or wrong I also started the pump and having it running at 1,500RPM so hopefully the start up guy wont be mad at me. 16,000 Gallons...
