Hi all,

Was referred here by a friend, what an amazing community. My pool (20339 gallons) had a few super-unreliable pool guys, the pool turned green, and I decided to maintain it myself. The pool was somewhat neglected for a few months, and while I was cleaning debris out of it, I didn't bother with the chemistry at all (knowing it's wrong).

After reading pool school last week, I fixed my metrics and started SLAM:
1. Brought pH down with Muriatic Acid to ~7.5 (was 8.4 or higher prior)
2. Brought CYA up to 40 (was 0 prior)
3. Brought FC at 16 ("SLAM" level in PoolMath) with liquid chlorine only
4. Replaced my cartridge filters (old ones were not replaced in 3 years, completely fallen apart) and noted the new clean PSI

I've been keeping FC at 16 for 5 days now. Brushing daily. Running my pool robot. I don't have a vaccum.

The water looks A LOT better, but I still have some stains / areas that look green - mostly in the center of the pool.
Brushing the walls/floor of the pool does occassionally bring up a green cloud, so I suppose I'm not done.
But curious how I'm doing so far, and any tips on where to take it from here?

Congrats on the progress.

You need to identify the stains to figure out next steps...
