I have a tetratec 700 and an eheim ecco 2234 (I returned a eheim pro about a year ago). Got to say I haven't had any problems with the eheim, but the tetratec seems to filter better and the filter compartments are better thought out. Will be throwing the white filter pad though once its clogged and probably sqeezing in another bkack filter pad in its place.
