Adjusting chemistry with 100% water replacement

[cpoplsc]

Checked the chemistry tonight.

pH 7.0
Chlorine -- 0
TA 90
Ca 260

The water is clear. Some scum/algae at water line (at corner that cover has cut straps). The chlorinator is after the DE filter. I missed the pool store but I have a fair amount of shock (calcium hypochlorite), some pucks (tri-chlor), soda ash and baking soda. The water level is below the skimmers so I can't start the pump until water is added (pump is very touchy w/ air). It will take 4-5 hours to add enough water. I'll see how long I can hold off on pulling the cover tomorrow while we are working on the filter. It is supposed to be cloudy and rainy. The pump is disconnected from the filter.

I'll prepare to shock as soon as we get the pump running.
