Final: Mame update

having tested the overflow in a spare tank with freshwater i found the venturi tubes inner diameter to be too small. Though the system did work during the priming stages the water in the tank would get close to the rim and i didnt want to take the chance of it flooding. So in an attempt to bore out the venturi the bit caught the acrylic and cracked both venturis down the middle of the pipe. For those that are planning on building a replica down the line i would recommend buying 1/4" thin walled tubing for the venturi. Overall though the project has been fairly easy to do and the cost was only $25 for all the material cost that is buying the tubing at full length as well (6ft). For the time being I'll be going a different route with my personal reef tank and hope you guys enjoyed the build.
