I love my Eheims but those green tubes just don't sit well with me. Not the flexible stuff that leads from the filter, but the rigid intakes and outflows. Is there any easy, inexpensive way to replace them with black?
In other words, is it better to go down in diameter or up?
Will using an inlet tube that is larger cause the motor to have to work harder?
The Eheim installation kits are colored gray. They look alot better, and work better.
