The filter pressure is 5. I backwash and rinse it every time I attempt to vacuum the pool. This morning there is still sediment on the bottom of the pool. It's less than yesterday but I feel as though the vacuuming just stirs it up more than vacuums. I will order a good test kit per your recommendation, however for now all I have are the HTH test strips. Everything is dead on except for the chlorine which doesn't even register.
Here is what I found for ingredients for Bioguard Smart Shock:

Multifunctional formula

The only other "chemical" added to the pool is the Bioguard chlorine block I place in the skimmer.
