You have a filter problem. How old is your filter, and what model is it? It could be as simple as not enough sand, or it could be damage to laterals inside the filter. What you vacuum should never come into the pool.

One possibility is that the sand became channelized, ie paths developed that let water go through the sand without really being filtered. Removing and then replacing the sand will take care of any channelization.
The height you fill sand up to varies from model to model. You should look it up in the manual for your filter.
