Can you make a skimmer too tall? I was thinking about adding some height to my EuroReef or just making a taller recirculating needlewheel.

I think its only too tall if the pumps can't handle it.

A needle wheel can be to tall. A needle wheel pump is only capable of injecting water so deep. Look up Spazz's DIY Dart Needle wheel. The water height impeeded the pumps ability to draw air. Admitedly his chamber of water was quite tall, but it is a consideration. From a reaction stand point, the length of the bubble rise is very important. The longer the verticle rise, the better the bubble dwell time will be. So as long as your air injection system can handle the height, then add all the height your system design will allow.

I believe someone has posted pics, here, of a 6 feet tall skimmer.

Yeah. Many of the counter current skimmers are very tall. But, it uses a very different concept.
