Pool still cloudy but can just see bottom now! From 9:00PM last night to 8:00 AM this morning the FC dropped from 26 to 24. CC was .5, I have been testing 4 times a day and brushing and vacuuming every day. I really don't think my 250 lb sand filter is doing the job. I changed the sand 2 years ago. I think I will put some DA in it. Pressure was holding at 17 then slowly went to 19. Pool color is a medium/light blue.
Fantastic site! Never saw it before! Algae is killing me,HELP!

Sounds like you are getting close to the end, keep up the good work.
Adding DE to your sand filter will help with the smaller particles. One thing to remember is that sand does not wear out, the only maintenance it should get once and a while is a good deep cleaning.

CYA does not change in the short term unless you drain a significant amount of water from your pool. So no need to test every day. Once a month is fine.
Take care.
Take care.
Thanks for your reply mknauss, things are looking up! Drop of FC from 8:00PM last night to 8:15AM this morning of 1 (26 - 25).
FC = 25
CC = 0
pool much clearer, not as clear as my daughters pools (inround pools put in last month) but I can clearly see the bottom. vacuumed brown residue from bottom of pool (not a lot). Brought FC up to 26 again this morning. How would you proceed now?

Am I done? Pool is crystal clear, FC drop from 8:15PM to 8:00 AM this morning was 1, CC = less than .5. There is still a little brown residue in the center of the pool this morning (the pool water circulates around the pool in one direction so stuff congregates in the pool center) heavy rain expected this afternoon. Should I continue one more day? A lot of work, BUT IT WORKED! Now to my neighbors 20,000 gallon inground next door! It is dark GREEN! Going to order a test kit for him. Thanks!

Good for you being a wonderful neighbor! Are they ready to accept TFP! Be careful using the 'bleach'
word around them.
The only issue I see is the residue you see. You have a sand filter so I suspect it is just not capturing the really fine stuff.
I would think you can let your FC drop and then stay within the Target level for FC. As you add your liquid chlorine manually be sure to add enough that when you test the next day you find your FC in the Target level. Assume your daily loss is 4 ppm right now and then adjust if your FC rises.
Good job --

Thanks mknauss you have been a great help! I am going to go one more day at the high level to make sure, plus wanting to see what the heavy rain this afternoon does! I gave up last year and just closed it down! not this year! Take care and THANKS AGAIN, and yes I am a believer!Good for you being a wonderful neighbor! Are they ready to accept TFP!

Pool is still CRYSTAL CLEAR after a week! Fantastic! Thanks so much for your help. Keeping FC about 9. Am going on vacation tomorrow for a week so I will raise FC to about 14 and have one of my daughters drop in a gallon of 10% on Monday and Thursday. Is it safe to keep the solar cover on at that level?

Should be no harm to a solar cover. It will reduce your FC loss due to the sun. I assume the pump will still run some each day.
Pool still crystal clear!!! Going to shut it down tomorrow. Got my neighbors pool clear too! ordered a kit for him and we got it cleared up. He has a DA filter and I couldn't believe how much faster it filtered the algae out compared to my sand filter. Thanks again for all of your help! Water too cold to swim now.
It would be best to wait until the water temp is steadily below 60°. I won't close mine until October unless we get a big cold snap. You could set the pump to run 3-4 hours a day and maintain your FC until temps drop more.
