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

[poolprobe]

Close yet so far away definitely describes how we feel at this point. The patience part is getting more difficult as we watch this water. It's clearer but again foamy. Can we still have a live algae bloom after all of that bleach?? can algaecide added almost 2 weeks ago still be the cause?? It truly is frustrating and all consuming.

So, after the 48 hours of pump off and waiting for floc to do its thing, we vacuumed to waste and refilled. Chlorine dropped to 1.5 after re filling so we added 3 gallons of bleach last night and let the pump run normally. This morning we woke to foam on top of the water again
Water test results this morning: Chlorine=5.10, Ph= 7.3, CYA= 40 (these are still from Walmart 6 in 1 test kit...still waiting for the one ordered off Amazon)
As of this writing we are planning to vacuum regularly and then backwash because of 19 pressure gauge reading. Then we'll refill and check chemicals.
After that we're unsure what to do to get rid of the foam.
Note: when water cleared there were leaves and debris on the bottom that we couldn't see before and didn't get cleaned up with prior vacuumings. Those have been removed for the most part.

My husband wonders what would happen if we just double or triple shocked...add 6 gallons of bleach to try to get rid of the foam and then deal with other chemicals later?

Would appreciate instructions from here...graduation is Friday/party is Saturday.

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.
