Thanks for the reply Janet.

Sorry for the delayed response. We've had a lot of rain so it's been tough to tend to the pool.

Good news is I can see the bottom!! At least in the shallow ... and partially in the deep. Also, Ca Hardness is within acceptable range: 130ppm on 6/21 and 150ppm as of 7:00 tonite. Bad news is it seems to be rising. Here are the rest of my readings from the last couple of days:

FC: dropped from 10.5 on 6/21 to 4 tonite.
pH: still too low, but rising. Added 1.5 boxes Borax in the last 24 hrs.
TA: holding steady @ 20
CYA: gone from no reading to 40 as of this AM

Here are the answers to your other questions.

-Pump: Based on the label I can read, A.O Smith Century Centurion 230V / 6amp.
-No particles blowing back into the pool
-Pressure gauge is completely shot. I've ordered a new one that will hopefully be here soon.
-I have backwashed a lot because of the algae and it seemed to help the leak on the top of my filter. Initially once a day, but now maybe twice a week.

The sand probably needs replacing since it's 10+ years old, but I really don't want to have to undertake that right now if at all possible to avoid.

So, what should be my next steps? Keep getting the pH up obviously, but should I focus on the TA? Should I add a puck to the skimmer since the chlorine's dropping? Oh, also, I spread the stabilizer directly into the deep end, and it looks like a bunch is still just sitting on the bottom. Guess I should've diluted, but nothing about that on the package label. Thoughts?

As always, thanks for the help.
