Long time lurker, first time poster. Please excuse the length of this post... I hope I get things right. I understand folks like photos -- so here you go.
Quick intro. House purchased September last year; got to enjoy a few months of pool after getting water clean & clear. I have no idea what I did, so now I keep a log. Had scheduled opening for mid-may, however due to MIA pool guy I ended up doing it myself. (And saved $400.) This will be my first SLAM & TFPC experience.
I've read Pool School up/down/sideways/front-to-back so I hope I'm on the right track.
Water was green/murky upon opening - lots of dust/dirt and algae I assume. Deep end was black.


Didn't have my test kit yet so I shocked the heck out of it (12.5%) just to keep things from going to swamp before my kit arrived. Initial cartridges were ones that came with the house that had seen better days. The green began to clear. I brushed & vacuumed to waste a few times a day. Lots of rain here, so no need to add water. Cleaned filters, repeat. Kept adding chlorine. Lots of brushing. LOTS.

Here's a progression:
So - there's where I am. I'll do the OCLT tonight; I have a feeling we might pass.
My question is this: the water is very cloudy; it looks kinda clear in the shallow end, but can't see the main drain in the deep end. How can I clear it up fast? The pool is painted (not by me) and it's chalking -- lots of brushing took place.)


We also have our first pool party of the year scheduled for next weekend so I'm in a pinch. I'd like to be able to swim and see my toes.
Looking for critique on my methods so far; and any suggestions -- obviously next year I will SLAM as soon as the cover is off.
Also have questions on raising CYA after passing OCLT, but that can wait.
