Just got a new liner installed yesterday and am in the process of filling with city water. Prior to old liner being removed, the water turned into a chunky green swamp. Plumbing is all still winterized as the pool was never opened this spring (hence the swamp). While the pool itself it crystal clear with the new water, the skimmer and the bottom drain both have some algae residue on the walls. Once I get the water level up high enough to begin circulation, should I still SLAM the pool? Currently both FC and CYA are at 0. If i do SLAM, should I first establish baseline levels - say CYA 50, FC 6 - for a few days before SLAM? Or should I dump everything in at once or adjust one parameter at a time (if so, which order?)? Thanks!!
Current Levels with city water:
FC 0
CC 0
pH 7.3
TA 40
CYA 0

Also, levels I was going to target were:
FC 6
pH 7.3
TA 60
CYA 50

Sound good??
 
Nobody scrubbed the skimmer and drain while it was empty? Too bad.

I'd be tempted to slop some bleach in the skimmer and scrub and rinse while filling. If it isn't too cold, maybe even the drain. If the water level is still low enough, you can avoid diving por awkward brushing from a distance.

Just follow the SLAM article. Circulate water, test. Adjust pH, add CYA, reach for the bleach. With zero CYA, shock level is 10 FC. You can target that initially, but as the CYA dissolves, you'll need to raise that. I suggest only aiming for 30 CYA initially, and SLAM at 12 FC. You might even pass the OCLT before the CYA is done dissolving and registers. But when you're done, add the rest of the CYA you want.

Thanks for the speedy reply! Would adding some algae treatment (poly) be wise?
