This pool was handed over to its new owners just a week before the below image was taken.  The owners were shocked, however upon closer inspection we found a faulty pump and underperforming salt water chlorinator.  

After replacing the old Hurlcon pump with a new AstralPool P320 eVo we commenced the pool clean up.  On day one we shock treated the pool with liquid chlorine, acid and a Lochlor algaecide.  The pool was then left running long hours for two days before we returned to vacuum any remaining debris from the pool.  You can see the result was spectacular.
