Herbie Method for DSA 65 Rimless- Need Help

[rchavez]

Hello, I would like to see if the Herbie overflow method would work on my new tank build. The tank will be in my living room and I would just like a quiet tank.

Specs:
65 DSA Rimless (Reef Ready)
2 x 3/4" Return holes drilled, 1 x 1 1/4 Drain hole drilled
PM 30 sump with 2 drains
Tunze adjustable return pump
I would prefer to hard plumb it, I'm tired of leaks and salt creep. (Open to suggestions)

Questions:
1. Can it work with the current holes drilled?
2. Should I use the 3/4 returns as the 2 Herbie drains?
3. Should I use 1 3/4 and the 1 1/4 holes for the 2 Herbie drains? (which one for the main & which one for the emergency)
4. Is this a good idea?

I have posted some pictures below. Thanks for your help! :dance:

I would use the 1 1/4" for the emergency and the 3/4" for the herbie. I have a 40b plumbed almost the same with 3/4" herbie and 1" emergency. The return is over the back. If i would have known about the herbie setup when i built that tank i would have done it just like yours with three holes, the third to accomidate the return.

Agreed on the 1 1/4 for the emergency.
Fine tuning the drains requires a Ball Valve.
I read that combining the drains and then a valve will help eliminate constant adjustments on a dual valve set up.
I can attest to this fact!
Someday I just might have to redo mine.

Thanks for the responses guys. I was thinking using 1 of 3/4 drains as the gate valve drain and using the 1 1/4 drain as the emergency drain. The second 3/4 hole would be used for the return of course. Phxreefer, how did your setup turn out? Is it quiet?

Hey, definitely go with the ball valves on the drain and return. Don't leave out unions either. I have unions on both my drains and also my return. They allow you to disconnect parts of your plumbing easily. I never used mine for the first year and a half but then my drain got fully clogged and got it unstuck by simply unscrewing the union and cleaning it out really quick.

I would run the syphon straight through the bulkhead with no standpipe; and use the larger bulkhead as your backup standpipe. 3/4" has a rather small area but it shouldn't have any problem syphoning what a pump through the same size pipe can send it.
