No your being a help, looking at the list
These are fine
Lever not set to fully “ON”.
Hose lines polluted.
Hoses buckled or too long.
Too many additional devices in the hose system (e.g.: CO2, UV clearer, etc.).
So I will check the basket first and see what that does and then if thats ok its onto the Filter
Suction basket polluted
Filter polluted.
