Yeah, I did at first then a buddy of mine got one and he told me it is a pain to swap stones out. He also has the Vertex and he says it's so much easier to deal with than the Vibe and wishes he would of never wasted his money. That is good enough for me not to buy one. Then the other reason I decided against it was, I didn't want to run a manifold or another separate pump in the sump, plus use up another spot on my EB8 and have all the cords hanging around. I'm trying to keep this as clean as possible. And the vibe also can't sit in the sump, it needs to be outside of it somewhere.
Makes sense. I love all things vertex so can't go wrong there.
