That should be plenty DE then - adding more is just going to reduce the amount that can be filtered.
Sorry to say that at this point it's just time. The good news is that cloudiness/turbidity is a logarithmic thing (like the gradations on your CYA tube), so it spends a while seemingly doing nothing and then should be much quicker toward the end. Once you can see the shallow end, the rest goes much quicker. At this point, continue maintaining FC at SLAM and let the filter do it's magic. Have you tried changing where the suction-side valves pull from? Like pull more from the main drain than the skimmer? It probably won't change much, but combination of allowing things to settle more and pulling from main drain more might help it clear faster. But really it's just a time thing.
I probably would. I would think most of the cloudy water is nearer the bottom. I mean, it all gets mixed together, but it's all about circulation, and maybe giving your main drain more responsibility would help keep it better circulated during the filtering process. I mean, we're talking small percentage improvement, but it could help.
So once all three aspects of the slam are met, what does the FC have to go down to before it is okay to swim in? I will need to check the pH again too.
I feel your pain with waiting so late to get started.. "never again" has been my favorite 2 word phrase since June 2nd. Kids finally got to swim yesterday and today. Thought those last couple of feet would never clear!
pypeke I am a noob when it comes to this level of awareness about my pools chemistry. Have owned the pool for 13 years but this is the first year with a proper test kit.
I plan to check my chlorine every day until I get a "feel" for my pools behavior in my climate. I keep an excel spreadsheet to log all my results, I test pH, TA and CH every 3-4 days as I do not expect these to change much and CYA I will check every 2 weeks and then monthly, since I only use liquid bleach/chlorine, I do not expect my CYA to change much, I certainly do not expect it to increase.
As far as my testing reagents, I assume I will use a bit more this first year and potentially into next as I keep a tight leash on things. Again, having used strip tests for 12 years this is a whole new level for me, but I look through pics of the "pros" on TFP and my competitive nature will not accept anything but crystal clear clean water from now on.
The way I see it, by NOT purchasing Algaecide, Floc and Clarifier ever again, my reagents in my mind are free. I am not looking to maintain my pool for free, only looking to reallocate my dollars to what matters most. If in the end I save a few bucks ok, but I was fine with my pool maintenance budget prior to this year, I am just getting much better results and peace of mind.
