What model/size of pump? A more complete signature really helps. See mine.
I just got my test kit, and for the salt test it says use sample tube # 9198 to the 10ML mark. I can’t locate tube # 9198
FC .5

Most of us find that our pools like the TA a tad low. Where is yours? If pH is stable, don't raise the TA.Got all my levels pretty much in line except TA is a tad low but I’m working on it.... I will update you on what I have done

You need FC, but as you did not test CYA , do not know how much. Keep a minimum of 3 ppm FC if no CYA in water. See [FC/CYA][/FC/CYA]
If your CH is really 30, then you are dissolving your plaster pool. What is the pH, TA, and CH of your fill water? How much do you use fill water?
You need a minimum of 250ppm CH in the pool.
Need a test for CYA.
Take care.
The 1.5 hp SuperPump will hit about 90 gpm during a backwash. That's about 29 gpm per square foot of sand surface area.
Ideal flow is about 15 gpm per square foot of sand surface area.
So, your flow rate is almost double ideal.
It might be worthwhile replacing the impeller with a smaller size.
A SPX2607C or SPX2605C would work.
Also, get a k-1766 salt test kit.
Does the debris disappear when you try to net it out or can you net it out?
