Issue: Over the past month, my 20x30 pool filtration has been dealing with an algae bloom, very greenish water, and the usual desert sand here in the desert S/W. The PSI is above 40 instead of the usual 30-35 or 25-30 after a cleaning. I fully cleaned the system last week and the PSI was inb the 30s but then went back to 40 psi after a day. Back flushing every day since drops the PSI to ~37, but within 15 minutes it's back above 40. The pool color is actually an amber with fine bilogic ~filaments in the water at this time. Similar in color to pic 1.

Cleanings - Last week I fully cleaned, and now today I have attempted another full clean. But this time, the filter units are significantly holding water, and I'll call it "biologics and sand" that has an odd oatmeal texture over the filtration units. Spraying the units removes it, but the retaining water gives me concern.

Help Me, Obi-Wan, you're our final hope I bought the house/pool three years ago, all built in 2013, and this is not normal and makes me wonder if the filtration units need to be replaced, repaired, or if I just keep soldiering on in my hell loop of cleaning, backwash, and do it again?

The picture was taken a year ago in June, so the gas price may not a viable hint.

When my Taycan has more SOC range than my Macan...something is up.

My 24 Macan 4 range does not match the normal SOC. In recent charging and use of my Macan, the range vs. SOC is off, and actual mixed city driving is *burning* more miles than the range indicates. No yellow or red warning lights on the dash. DC fast charging at ~20% did not receive a rate over 18 kW and took 20 minutes to add 6kWH.

I believe it is a Battery Management (BMS) miscalibration and will attempt a draw down of the battery, rest and recharge. (20% → sit → slow charge to 90% → sit). If that does not resolve, I will contact my local service center to arrange for it to be looked at.

Has anyone else experienced this with their Macan?

TLDR BMS Miscalibration and concern about slow DC fast charging rate.

Upon mixed city driving last night for a 60 mile round trip, my Macan started out with more than enough miles, though reporting to low vs SOC, to cover the trip roughly (65% SOC but only ~100 miles) but once at my destination, I was at less than 50 miles and sitting ate up 3 miles.

Fearing being stranded on my return, I DC Fast charged at a close EA five miles from my location, the trip calc substracted 10 and put me below the 40 mile range. I DC charged for 20 minutes, adding 6kW total, and it never got above 18kW during that whole session.

I made it home, slow highway driving never above 60mph with 31 miles from a 90 mile start estimation.
