75G herbie plumbing photos
had the camera out from cars and coffee so I decided to add some photos. I didn't really find a lot of photos regarding a 75G tank. So here some are. I'm no where near professional but learned a lot along the way. If I can optimize anything, please let me know
The sump is a 30 gallon. First baffle is 9", then the 2nd is 1 inch from the bottom of the glass and is also 9". The last baffle is 8 inches tall. I'm running the herbie method. I found the quietest point to be 1/4" away from the emergency drain. I was thinking about getting an U shaped clamp to make sure that the return line can never come undone. That's my worst nightmare |

Did you leave the emergency drain above the highest possible water line of the sump? I can't tell from the pictures. I like the final product. Glad it is working out.

It is not above the water line at the moment. I'll probably unscrew the union and cut it off in the near future. It'll take 3 minutes top. I'm really glad with the outcome. Thanks for the kind words.

Bum,
Do you have a link to the Herbie method?

Thanks for the pictures. Are you running the herbie with a trickle through the backup drain? I hear that helps with "self tuning" in response to different return pump flow rates.

It was a system popularized by an RC poster named herbie that involves using both holes on "reef ready" tanks (intended for a drain and a return line) for drains -- one drain is completely submerged but restricted with a gate valve, while the second drain is an emergency drain in case the primary drain clogs. Some people also trickle some of the flow through the emergency drain because it results in "self tuning" when the return pump flow rate changes. The benefit of the herbie method is that it's silent, doesn't introduce bubbles in the sump, and is reasonably failsafe.

Wow, the first photo looks so clean compared to what it looks like again. So far, so good!

You should take that metal clamp off on the return pump. It will eventually rust away. Get a nylon clamp or zip ties.

Indeed leeit. My next order from BRS will include the plastic clamp. I don't really trust zip ties.
