I passed two of the three criteria for fighting off the algae (FC/CC/OCLT) this last evening (I think I would've passed a couple days ago, but was out of reagent), but I still have the cloudy blue water. I can tell it is getting better, but it's taking it's dear sweet time. I've been running the filter (Tagelus 60 sand filter) pretty much continuously 24/7 since around the 27th or 28th (had a couple of nights off, because the pump got into a rhythmic hum that had me worried). I did backwash every other day and then I did about 3 days in a row, but my question is regarding pressure. It's clean pressure is 20, but it's not moving past that at all - eh, maybe 21. The gauge does go to zero when turned off and changes during backwash/rinse/waste. Do I need to backwash if that pressure isn't increasing? Should I be expecting pressure build up fairly quickly or does it just take longer than I'm expecting? I do have skimmer sock that I put on the skimmer the day before yesterday, but even before that, I didn't see pressure rising.
Including some progress pics of the pool to show the TFP method works!
