Due to not getting my cover on last fall until late October, combined with the giant Oak and Tulip Poplar trees within 15 feet of my pool, when I uncovered this spring (sometime around April 20) it was totally black. It looked like a freakin' mirror it was so black.
Using my TF test kit and following the directions on the post about clearing up a swamp, I managed to get it from black to green within a few days. However, it has been several weeks and there has not been much progress since then. I am able to clearly see about a foot or so down in the pool (along the sides), and I can see a dark spot in the shallow end when I use the net/vacuum/brush, but the change over the past few weeks has been minimal.
I would estimate there were about 8 inches of leaves in the pool when I opened, but I have gotten most of them out. I know there are still some leaves in the deep end, but because I can't see them, it is very difficult to retrieve them.
My test results today were:
FC - 4
CC - .5
TA - 70
PH - 7.4ish (I'm not a good judge of color on the PH test)
I didn't test the CYA, but it has been holding steady at around 30-40.
I was backwashing several times a day, but due to a lack of rain and my home water source being a well, my water level is pretty low so after reading on this site that you only need to backwash when the pressure reaches 6-10 psi above normal, I have reduced the frequency. The crazy thing is, my normal psi last year was around 20-22 (with the heater connected) and when I first started this spring it was at about the same psi (without the heater), however over the past two weeks the average psi has dropped to about 15?!?!
Anyway, does anyone have any advice?
