I think this needs to be stickied soon...........this has got to be asked weekly !!!! I know I asked this when I got my first 9005.
What do you think Roger ??? :thumbsup:
Since the search feature rarely works........the "hole question" should warrant a sticky !
Anyway.......... When using the 900? with the sump kit........you can plug the hole, so you wont get that annoying, dripping, running water sound. It doesnt seem to affect performance at all in my opinion. When using the 900? inside the tank........the hole needs to be left open.
