:wave: You-hoo....over here....Red Coral again...we have bulkheads.:mrgreen:

Both of my bulkheads were from red coral, other aquarium shops or a hot tub supply store maybe. Not sure. As for attaching a filter head just use pvc fittings. If I'm understanding you right you could just use a length of 1 1/2 pvc pipe to a threaded fitting which you could attach the filter head. And yes bulkheads come with threaded ends as well if you wanted to purchase new ones. What I would recommend is to go through some of the tank build journals on this site to see how others have gone about their builds. Useful tips and tricks, it alleviated many of my issues. the 1 1/2 inch drains are good, have you looked into a herbie style overflow (search this forum). the return lines will depend on your return pump. If you have a pump that has 3/4 inch output I would recommend running that the majority of the distance if not the whole way.

Fishytime, what kind of a deal can you get me for 4 holes and 4 bulkhead fittings? :p I live in the south east, driving up there... gotta be worth my while lol.

I am not familiar with very many "drainage/overflow" models at all outside of a typical overflow?. I was planning on basically having just this inside my two drain holes (One with a 1.5" diameter)

Thatd basically be it for drainage as it'd be at the desired water level line.

As far as my understanding of herbies goes it just limits the drainage so that no air goes with it, thus lessening the sound? Is that it? I really am lacking knowledge on the design but am open to other options. I would like to keep as much tank space as possible though and feel like this design is close to as good as overflow boxes based on what Ive heard and Ive seen it in LFS's as well. Seems like a great design to save space in the tank and still oxygenate the water and skim the surface.

By the way, I just wanted to say that so far, Canreef is kicking the snot out of Reef Central for being helpful. I love how this is local and I can get some real good advice on where to find deals and what not. Much appreciated.

And the search function works too:lol:... I will pm you with a quote.

Hi ,
Welcome to the best board going. :D

You would likely do even better taking the discussion to the regular forums for it, like reef forum or equipment. And then when you start your build, start a thread in the journal forum.

Thanks
and good luck with the new tank. Lots of help and info on here. We also have greta info in our library.

Yup...lots of great info......spelling sometimes isnt the best but hey:razz:..... Sorry Doug couldnt resist.:mrgreen:

Ok, read a bit more about herbies. Still havent read as much as I could about actually constructing one, but got a general understanding. Gate valve is installed to "fine tune" water flow to the sump so that can get a bit of an equilibrium in the overflow box where there is hardly any water sound to help make the tank silent.

Sounds good, but wouldnt I get the exact same effect with my design? I feel like the herbie results in lost air injection into the water. How is this remedied?

Ideally Id like to get a drain pipe that is turbulant inside it and a bit larger than needed so the water sloshes around, mixing with air, but remains quiet inside the pipe, rather than sloshing around at the surface in an overflow.
