Plumbing question ?

[IanWR]

I think what you have would work, I don't know if it is optimal. For example, with the herbie I don't think you will need a bubble trap off the drain since you shouldn't be getting bubbles there. Not knowing what all your equipment is, it does look like it could be simplified. You seem you be using your eheim to run a skimmer and uv? You could scrap the cannister and t off the return to run uv and/or reactors (I assume the skimmer actually has its own pump ).

As for the herbie specifically, looks like you have it right. Your 2 drains are not tied together, you have the siphon lower than the emergency, and you have the drains terminating a couple inches below the water in the sump. Looks good!

Hi Ian,
No the skimmer doesn't have his own pump this is why I use the eheim canister... Will be upgrading skimmer eventually.

I am reusing my previous sump which has already the bubble trap

The tank came with the plumbing and one of the tube is larger than the other one...should my emergency drain be the larger of the two ?

I'm thinking yes ...

two things i notice that i would change but arnt life or death and just personal preference

one is the emergency i would have it just above water level in your sump so that when its in use you know theres an issue , if its submerged youll never know its running only to look to see if water is goling down the pipe, if you plan to have a trickle going down it then run it just at the waters surface.

the other is i would feed my fuge with the return pump and a valve to control the flow , that ways your not diverting water away from your herbies drain and you can control how much flow you want in your refugium and fine tune it.

my 2 cents:P

Personal preference ...
I'd use the larger drain as the main

And ya, about the self-priming pump, good catch Cal

I'd recommend the heater be after the pump so it's pushing not pulling through it. Any air that gets into the heater may become trapped and cook it ... maybe never happen, but a thought

Thanks Guys... great info here.

Found a foot valve

Will be dry plumbing the tank on Friday or Saturday but got to move it into the fish room first.

Hopefully things go well.

I may consider using a Durso for your main siphon drain. The reason is, you will have stagnance at the bottom of the overflow. Using a Durso will create flow in the bottom, and all you need to fo it place a siphon break at the top (assuming your sump cannot handle the volume of your overflow. Secondly, I would use the emergency as a trickle, since protein will build up on the surface of your overflow otherwise.
