So since the beginning of my 20 long reef build I have been contemplating the addition of a sump. I have a brand new 10 gallon aquarium that has been laying around my house for about 6 months. Originally it was going to be a planted tank in my bedroom until the wife rearranged furniture and left no room for it. So after watching a few videos on Youtube I decided to build a DIY overflow. Here is a link to the video that features the design I will be using: HOW TO: DIY Overflow - YouTube
I have a few questions though before I get started. The whole idea for a sump is very new to me as I have never had one before. My first and main question is, what size pvc
should I use I am thinking 3/4" will be sufficient but I wanted to see what others thought. I am pretty sure I have seen others on this forum who have used the exact same design. Thanks in advance for any insight you all can provide.
