Having algae blow back into the pool is a problem. If the algae is DEAD, this indicates you have a filter problem. If the algae is ALIVE, you'd be better off vacuuming to waste.

Looked at your Pool Chart data.

If you want a clear pool on Aug 4, you probably should:

1. Vacuum the algae to waste;
2. Purchase and use a SINGLE dose of a locally available pool clarifier;
3. Open and check your filter for adequate sand, and for lumps and channels.
4. Report COMPLETE test results (do you have a K2006, or have one ordered?)
