I decided to do a running water feature in my tank that I am currently build up, and yes it is a vanity feature and not needed. However a feature that got my wife involved in the planning and building so I am ok with it. I have however run into the issue that John discussed in the past and had to tear the whole background apart to get to it. This time I built my enclosure where a dead pump is a 5 minute fix. I went with an external pump/filter system. water is filtered, and no electrical in the enclosure. Beats the 2 week fix on an old build that the pump was inside.
