Here in this pool there is nothing to complain about. Constructed and filled with lightning speed, the fun already begin soon. The accessories can also be seen. Only the cartridge filter, I would not want to connect. Unless you like greasy water and much Work and money the cartridges daily to clean / every 14 days to buy new. Here at the hardware store they were to High season ever sold. (4 years cartridge filters were the nightmare;)) Have connected a sand filter. This also does not have to run all the time. Have they been 10 hours a day let run. Water is crystal clear. Now go to the runtime down slowly. Have fun splashing :)
