Filling pool tomorrow

[xJustin]

The fire department is bringing us a hose tomorrow so we can fill the pool. I've gathered that using bleach to get the chlorination to an acceptable level is the best option, is this correct? We spent this week refinishing the tiles and acid-washing the walls and floor.

You certainly don't want water sitting around for long without chlorine. Bleach is great, but, how big is this pool It might take an unwieldy amount of bleach.

[xJustin]

150k gallons.

And it looks like the upstairs guys don't want to spend any money, so meh. Looks like the granulated shock is all we got. I hate using it because it doesn't mix well and settles as a sludge on the floor.

Bleach is not practical for this pool. Ben is the best one to advise you on a commercial pool. He is the only one who has the experience dealing with these huge volume pools. He'll be around later.

What's in the granulated shock, cal-hypo or dichlor?

[xJustin]

Calhypo. In previous years we've had to use 50 lbs a day just to maintain a steady level of chlorination. We have two chlorinators that use the round tabs, but I'm not sure if they work full strength. One seems to empty out the tabs daily while the other takes about a week(both turned on the max setting)
