Seeing as Albert just built my tank in the fall, thought I would offer my 2 cents. I am fairly new to this hobby (< 1 year) and am realising a lot of it is trial and error. When I had my tank/stand built, I thought I had everything exactly the way I wanted it, and wouldnt want anything done differently. Now that is is set up & running, there are several things I would have done different on both the tank and the stand. Overall I am definately happy with the tank the way it is, but when I upgrade
I know what I will do differently.
Seeing as you seem to know exactly what you want, I think you will be fine. They herbie for overflow is awesome as many others will attest to, but I recommend tracking a gate valve down, even though Albert will tell me to suck it up and be patient with the ball valve
Goodluck, cant wait to see the build thread!
