Im using the Custom Sealife T2 velocity pump...
And Im not getting the difference... Only way I can think of to ventilate it would be to stick a fan infront of the pump (or below it) which again is just cooling the housing not the actual motor coil. The outside casing of the pump is completed sealed. no way for air or even water for that matter to get in.
Thats where I came up with the idea of using the water to contain this heat so it doesnt heat up the inside of the case....
PS. patience is a virtue. newbie alert
