murph, thanks again, no it's not a pre made sump, it's how I have my DIY 55 sump/fuge now and it works pretty good, also have a DIY skimmer that it fed like the last diagram, also works very well, the only reason I'm tossing around a new sump build is because the 4 foot 55 gallon won't fit through the doors on the new 180 cabinet, and I refuse to re-lift this tank off the stand to get it in, so I'm going to use a 3 foot long tank as the new sump/fuge, as it will slide right in... I'll do some searching for some of sign guys sumps he has on here, and then probably go with one of his designs, But hey thanks for all the great insite every little bit of help in this build will make it much better in the long run, mainly because the wife says you wanted a 8 foot tank one day now you have it so that's it, no more, do it the way you need to because this is it..
little does she know I really want a 10 footer someday.
Thanks Greg
