Finished installing weir in far skimmer. Had to break off a bit of concrete that oozed in the corner. Removed leftover rod of a spring-loaded weir.

Installed weir in near skimmer. Removed last bits of float valve o-ring. Could not remove check valve for inspection. Could not figure out where check-valve-pipe leads. Presumably, it's connected to alternate water intake, but I didn't see any water moving in the pool when i fed high-pressure stream (garden hose) into it; the water did flow somewhere and it was not towards the pump. So the mystery remains till I can see pool bottom clearly.

Ran filter for about an hour. The filter wasn't pristine, and previously (5 days ago) filter pressure reached 35 before I put pump in recirculate and left for long weekend. Somehow, it recovered.

Wanted to run filter for its daily exercise. Due to crack in the manifold and abundance of DE in the water, I decided to use only 2 lbs (1/3 of normal) of DE. And I forgot to switch filter from Recirculate to Filter. Thus I've added 2 more lbs of DE to the pool. Cloudiness of the DE-rich water coming from returns was similar to general murkiness of pool water.
Ran filter with old manifold for 30 mins. Leaving pump in recirculate mode overnight.

at this point, I'll aerate the pool. And then, maybe, repeat acid application. RN, TA is within range.

*Filter quickly built up pressure 30psi. First backwash showed whitish DE being washed away. * Multiport valve definitely needs spider gasket replaced: it can't seal properly when I switched it to RECIRCULATE mode (after several FILTER ->BACKWASH ->FILTER cycles performed after cleaned filter was installed. Before, I had flow 90. now I can get ~45, at most. * Filter housing gasket shrank during the day - while I was washing grids, - and i had trouble putting the dome back on. * Turned pump off; scheduled it to come on at midnight for 5 hrs - to stir up bleach again.
