Tidepool 2 sump can be seen on
www.marineland.com go to consumer prducts and there is the picture of the sumps as well as dimentions. The pump is a power jet 5000 made in Italy for Laguna ponds . It moves at least 1500 gph at 0 head. It is only a year old and has only been used for nine months. Made to last and not cheap. It by far is nothing fancy but works very well. Sorry I haven't caught up with times and don't have a scanner or a digital camera. But if you go to any pond sites I'm sure they would have a picture. If you have any more questions pls ask. HTH
