I don't seem to have the flow that I had last year and the water just will not clear up.
When you wrote this, I took it mean that your flow rate had decreased but if the pool just won't clear, that is either a chemistry issue or it could be that debris is passing through the filter due to an issue with the filter. If the pressure is the same, the flow rate should be the same as well.
If you can be a bit more descriptive on what you mean by "will not clear up" (e.g. cloudy, green, can't see bottom, etc).
Some history might help too. For example, did you just open the pool?
Lastly, can you see any debris coming back out of the returns?
