First let me start out that I don't use strip testing. Buttttt I received these free strips from pool time I think and decided to try them. Anyways it says my hardness is "high" which shows to be 1000 at the most. Should I be concerned? I have a vinyl liner pool 33' ROund.

First, the strips are testing total hardness which is going to be higher than calcium hardness!
Second, the strips are just not as precise as a drop based kit. What is your calcium hardness reading from a drop based kit. If it is very high then you might run the risk of cloudy water or scaling.
