That sucks and is a fear of mine... i lost my phone this weekend and had a hard time finding it, it fell out of my pocket into the flower bed next to the pool. I hope you get your replacement phone soon.
The silt/dead algae areas are just how the debris settles because of the water currents. Once a little bit settles it tends to attract more and the area of accumulation grows.
FYI, crystal clear water on this forum means you can see the screws on the main drain cover and can tell if they are phillips head or straight.
Ok, thanks for the info. The water seems clean and somewhat clear to me, and yet is still the same shade of green. The green dosen't really seem to lighten up, despite the water being clearer. I do know that clear is subjective, and I can see it improving slowly over time. Of course, the question remains this: as the water clears does that mean the green is fading, or no, the green remains but is getting cleaner??
