Im new to this site and just wanted to share my on going project. I have been putting a 250gal ply/glass tank together in my spare time just to do it and have learned alot of new stuff along the way. I have a pic and will post it to show what it looks like.
I would like to say that the stand is realllllly strong. I had this tank full of water and my friend and I were standing on it as we test filled it and we had 2-5yr olds swimming in it. LOL I had a few problems with the epoxy I used and found out after I had a small leak form on the 4th day it was filled. I had to stip all the epoxy off and have not yet resealed it, but found that westsystems epoxy or sweetwater epoxy is the stuff I should have used. Both will work great, after lots of research and e-mails to these companies I have found that you really do get what you pay for and both of these companies have sent me info that is very impresive. I just thought that this was some good info for you all to have.
I will explain anything you would like to know about this tank as for pics in progress I didnt have a camera at that time but Im planning on another big tank down the road once I have worked out all the bugs on this one. I used 10" pvc (sewer pipe) cut in half for my overflows, at the bottom of those is 1" pvc for drains to the sump. I used the same pvc for the return plumbing and everything is drilled through the bottom of the tank so I have nothing hanging off the top. I made the top slop so I could put the lighting in a plexy box inside so it dose not show aswell. I have redone the plumbing atleast three times to get it to work the way I wanted it to, the biggest thing I had problems with is the overflow tubes didnt have big enough holes drilled so the water went over the top of them insted of where I wanted the water line to be. I also made the return tubes come in from the bottom but realized the back presure would not be good and if the pump failed it would drain the tank. oops I fixed this by making the return pipes go to the top of the water line and then back down. I think this is enough info but please feel free to ask more questions.
