Do not know...............you mentioned that you were looking for a 1200 g/hr. pump the other day.
I would recommend the Turbo Sea or the Gen X. The price seems to have went up on the Turbo Sea, not sure about Gen X. They were in the $125 or so range........low heat, low noise, low energy.
I have been running each on closed loops and are very happy with them.
That Fish Place (Turbo Sea) and Premium Aquatics (Gen X) carry them.
