Finally finished the plumbing. Not sure I mentioned it before but the buckhead is 1". Therefore I use all 1" pipes and fittings. Let's see some pictures...
I decided to have only 2 holes drilled because I wanted to implement a herbie style overflow. I knew all about beananimal and its variants. For simplicity and less risk of breaking the glass, I chose herbie. After filled the tank with water and ran it for a week, I am convinced that my decision was correct. Herbie is quiet and doesn't need constant tweaking like some people say. At least I don't have to tweak the valve in 2 weeks that I run it. I will post my running herbie in a later post.
Return is from the top. 2 reasons for that, 1. coast to coast overflow. 2. didn't want to risk breaking the tank by drilling an extra hole.
Talking about the C2C, it's running better than I anticipated. I will have another post later.
From far to near are emergency drain, main drain and return pipe.
Bottom of the pipes. Since they are on the side, I built some support structure to support them.
You can see the section of the plumbing inside the stand. This picture was taken from the top trough the bottom tank glass. From left to right are return pipe, main drain and emergency drain. Main drain and return pipe are controlled by gate valves. You can also see refugium feed below those 3 pipes. For the "last mile" (last piece of a plumping section), I use spa-flex to have a more nature bend.
Return pump is a eheim 1262. It's quite. The only way I can hear it is to turn off all fans and pump from my other tank in the same room. Even that, it is only a slight hum.
Return is split to feed refugium section of the sump. Flow is set by a ball valve.
That is all for the plumbing. Let me know if you have any questions.
