Yeah that link is basically what I am talking about I think.


The only thing I worry about with that one is how the water drains down to a "U" and then back up. I don't like the idea of having anywhere in the drain line with back pressure or a place for things to get stuck easily. I think I will do something like this but without that "U" in there.

Thanks again, that gives me a good idea.

Plumbing is always interesting, one thing I've seen posted on RC about durso style, is they quiet down over time once you get a 'slime coat' on the inside of your pipes. My nanocube is running a 1" herbie and is almost dead quiet. It makes splashing noise entering the overflow box though, hopefully going to fix that tonight :)

Not sure if you saw this link I posted in some other threads, but it's a very neat concept I'm going to put on my 75g;

Yeah I agree, there is a different style... but I cannot find the diagram for the life of me! I think I have it in my favorite's at home though...

So whats the plan for backup drain? :razz:

No back up drain since I am not doing the herbie. Just the traditional single drain plumbing. Same as if say I bought an already drilled tank from the store with a single overflow.

You don't need an emergency as long as the drain keeps up with the pump. The reason for the emergency with the herbie style is because you are restricting the drain pipe so much that all kind of stuff could get stuck in there. Although on my big tank, the herbie is dead quiet and nothing has ever been stuck in it. The emergency drain is never used.

But I am sure you already know that :)

You just need to adjust the valve to get the water level higher and eliminate the splashing. With mine, it doesn't even look like water is going over the overflow I have matched it up so perfectly.

I was under the impression that the flow rate through a durso can change very easily, especially caused by salt creep blocking the air vent.

Personally I'm just a paranoid freak when it comes to a tank overflowing! Knock on wood I've never had a spill yet! I just prefer to have a measure of safety, "just in case".

Man I would love to have a cube tank... or a shallow cube like yours :)

Haha, you're killing me with this "I post 2", "You post 2" !!

The problem with the nanocube is I'm using the built in 'false wall', which has three chambers .. the center chamber runs at a different height (which has the drain), than the chamber where the water enters..

I'll post pics once it's all done, and I'll resist hi-jacking your thread :drinking:

Oh I see....yeah thats a tricky one then. Do you have an idea of how to deal with it?

The flow rate can and will change with any drain but as long as the drain can handle the maximum flow your pump can put out then your fine. In my case, the pump is so small it will never be a problem. So the only other problem really is things getting into your plumbing like snails and clogging it up. Which of course would flood your display. But with mine, there is no way anything big enough to clog a 1-1/4" pipe can get through that small opening in the overflow, so anything that may get into the overflow should just end up in the sump. If I had a herbie though, it would probably get stuck in the gate valve and slow the drain down making the water level in the display rise. The herbies are just much more sensitive to things getting into the plumbing because of the restriction. I love them though and wish I had the second hole for an emergency drain!

This is the drain plumbing coming off the back of the tank.

And here is what I decided to try near the end of the drain. Just another durso type thing. I don't know if it will do much but I seem to remember people doing this and saying it was quieter. I think I will cap it still and drill some smaller holes in the cap like the other one.

Anyone using this stuff? Does it regenerate well? I bought it because I like the idea of being able to recharge the media. Hopefully its worth $50!
