URGENT...Need help.. grad party 7 days...cloudy foamy pool not holding chlorine level

[PoolDoc]

I'm afraid the foam is from the algaecide you added -- and those algaecides are blended to be chlorine stable, for obvious reasons. Keeping the chlorine high may accelerate the breakdown, but I wouldn't expect it to disappear rapidly.

You can get a silicone based defoamer at pool store, however, those break down faster than the algaecide will. So, if you get some, apply it maybe 6 hours before the party.

It *will* come out on the filter, as you vacuum dirt. So backwashing frequently may help.
