I have small 8×30 easy set up pool. Is that ok to leave the blue tarp cover over the pool to keep from leaves falling from the trees and bugs out each night during filter pump running? Also when add three chemicals same night and turn on filter pump to run through the night? I use 1"tablet super chlorine put in filter pump (design for pop up pool),shock and algae once weekly is that correct?


Sounds like you have a good plan going. It is usually going to be ok to leave the cover on at night while the pump/filter is running. However, if you add chemicals (other than slow dissolving chlorine tabs), leave the off for a few hours to let the chemical adjustments "off-gas". This will help save on the life of your filter as well.
