Pool School

We installed 15' Intex above ground pool recently. We have followed the chemical care plan as recommended by the manufacturer. Needless to say, we are very unhappy with the results.

Their plan is very expensive. The chemicals are harsh. We still ended up with a terrible algae problem.

1) After working for days to try and get pool cleaned up, we are still having problems. Can we fix, or???
2) Should we drain pool and start over?

Heard of Pool School. Can we "attend" through this forum, or is there a fee for this. Please advise. Tired of this pool!
