Are there any parts common among these tanks?
At first glance the glass tank for the Atlantis 2 is the same as used for the Triton 2.
The seals for the glass are different, with a thinner seal on the Triton 2.
Are the connector pins and insulated rings physically interchangeable? (Triton 2 is gold, Atlantis is stainless steel)
I'm putting together an order including some common repair parts, and this would help.
@Tina can you forward these questions to the Engineering Department?
After checking with our engineer, Now answer your question:
The glass tube for the Atlantis 2 is not the same size as the Triton 2,they are not compatible.
The seals on the triton2 is not compatible with other Atlantis series tank.
The only compatible thing is the connector pin and the insulator ring under the base hardware.
