My Herbie overflow write up. (pics/beware)

It effects it in a good way. Lower level equals less suction head pressure on the pump, equals less flow, which means the level in the overflow drops because the gate valve is open too much for the lesser flow.

The gate valve is not static, as the level rises in the overflow, more head pressure on the opening, which flows more water. So there is an equalizing factor in play. As the overflow begins to rise, more head pressure flows more water for the given valve opening. Sort of self regulating to a point.

Now I only like my water falling no more than an inch, so water will back up and hit the emergency in one inch. If you kept the overflow say 4 inches low...(more noise) then it would have a much wider range of regulation.

 

Dude.... Im bout to give this a try.... Im tired of microbubbles and noise

 

Question.... do you need the split return line to tank? if not why you choose this way instead on a single return?

 

You don't "have" to. I came off my pump with 1" flex, then tee'ed to two 3/4" inch lines on each side of the tank. I was really just looking for max flow and least resistence.

 

Powerman... just to confirm everything ive read in this thread...

1" main drain is perfectly fine?

Place ball valve after the tee to fuge. ball valve will control drain to sump. ???

Ball valve is not necessary to fuge after tee?

 

Uh.. not sure.

1" is fine.

Mine goes ...tee to fuge then regulation valve then skimmer section.

Ball valve for fuge control.

GATE valve for Herbie regulation, water level in overflow adjustment. A Gate is a must. A ball valve is a headache.

 

What you not sure about?

ok cause Im sticking with my current bulk heads... 3/4" for emergency drain. 1" for main drain.

So im gonna have line coming in from main drain bulk head to a tee. then tee to gate valve. gate valve to sump (skimmer section). For fuge dropping down to a 3/4" line then gate valve then fuge.

I meant gate valve in previous post.

Im gonna go with gate to fuge just for kicks. It will drive me crazy knowing that I have a gate and ball valve. Reef OCD ;D

 

Too funny. Nice to know I'm not alone.

 

1" is more than adequate for 99% of reef tanks out there since it can almost handle 1000GPH.

 

WOW!!!!! This is absolutey awesome... SILENT AND BUBBLELESS. Im happy
