Localised bleaching - cause and impact?
Went away for two weeks so put an extra (but, so I thought, not excessive) number of chlorine tablets in a floater and left pool as is. Not pumping during that time.
On return, a small area of the floor (BESTWAY) has bleached, apparebtly below where the floater settled for the period (alternative theory is somehow it got concentrated sunlight during the two weeks of constant heatwave conditions).
Was the chlorine the cause?, and what is the potential short and medium term impact? Is the floor, now more likely to give out this season and/or crack during winter dry storage?
