I am determined to get the pool right this year, last year we were not consistent or knowledge enough so Algae 1 - Us 0.
Background
Our normal Pool cover ripped 2 years ago so we used a Solar cover over that winter. Last year when we removed the cover to open the pool a lot of leaves and crud went into the pool. We attempted to shock / open and managed to spend a lot of time and money but never followed thru. At best water was opaque, never clear.
This year, THANKS to this site I actually think I know what i'm doing !!
Last week, before removing the solar cover I removed all the leaves from the cover then I removed the cover (filled up 4 leaf bags 1/2 full). I removed any leaves from the pool (not many)and then I brushed the pool walls and vacuumed. Water looked very dark green / blackish with many, many, many visible small particles. I am running the pump and after backwashing when needed the PSI remains at @12.
Test results using @1year old leslie's 18-576
PH 7.2 (I had raised it from 6.8 the day before, hindsight should have waited until after the CYA / TA)
CYA no reading. Black dot still visible (done twice using 2 different leslie kits, above and a Leslie deluxe - age unknown although reagent looked clear) added 4lbs CYA Goal 35
TA 40 - added 42oz baking soda, will test again and raise to 60
Ordered a Taylor 2006c, should arrive on Friday. Hopefully Friday / Saturday start the SLAM
Started a deep clean of the sand filter today. At first the water was black with many, many, many small particles floating out. After 30 minutes (see pic) the water looking in was semi clear, I was able to see the bronze hose fitting but not the top of the sand. Still had visible particles floating around, granted not as many

Question ???;
Should I continue with the sand cleaning / give up and just replace the sand / or keep the sand, stop the cleaning now and after the slam is done clean and/or replace sand.
SLAM plan
Test TA / PH and get in range (60-80 / 7.2-7.5)
Test CYA Friday (added CYA Monday night, at least give me an idea of where its at) ??
Start Slam Friday if Kit arrives or Saturday / using CYA 35
Test FC every 10 minutes (read the ammonia thread ) ???
(using Walmart Pool essentials chlorinating liquid 10% at $2.50 gallon)
Thanks again to all for the wealth of knowledge. I have notes upon notes and am very looking forward to enjoying my pool more than the resident Ducks (which drives my Shepherds crazy)
