Hello. I am new here but not new to pools. I have been self servicing my 13,000 gallon in ground pool since 1998. The last refinish we had pebble tech surface and field stone surround added. I use a sand filter, pentair pump, Hayward Salt system and a Raypak 8450 Heat Pump. I have a Dolphin pool cleaner that we call “Petety”. Petety originally was a Polaris that ran a second pump motor. The new Dolphin is much more effective and consumes much less power. Looking forward to learning from the community. Bill.
