I have been wanting to build a sump for my 135 turtle/sunfish tank but didnt know how and there are not many "how to's" on the web just finished projects. i found this the other day and thought it was a great idea and very useful. let me know what you guys think. My idea to hide it is to hollow out a stump and disguise the overflow as a tree submersed http://www.3reef.com/forums/i-made/n...low-140523.htm
