Awesome...thanks so much for checking those things, Richard! I just wanted to make sure that we can get this finished off.
The pictures are showing a good deal of improvement and overall your FC consumption is not especially high for 30k gallons considering that at normal non-slam levels UV would use a good few ppms per day.
The only thing that seemed strange to me is this:
That's a pretty wide variance unless your pump is variable speed. Eg. On my system, I get about 7 psi if I've dropped down to 2100 rpms. Full on, I get 17-ish. Every system is different, and you ARE operating with the main drain mostly closed, but keep an eye on it and if you can, report "when" its low, when its high, etc. Makes sure when its low that there's nothing clogging your pump basket.
I'd think the variance would make it difficult to tell when to backwash. You don't want to backwash too often as a slightly dirty filter is better at catching stuff. But you also don't the pressure much more than 25% above clean pressure.
At an rate, you are definitely getting there. Keep up the great work!
