Question: Durso Or Stockman Pipe?

[Headless_donkey]

We are working a new 110 and I am trying to decide what kind of drain pipe to install. Initially I was set on a durso, but the drain is 2". This large plumbing means a full durso is going to take up a lot of tank space. So I was reading about the stockman pipe and thought it would be a good alternative.
Does anyone have experience with these? Are there distinct advantages and disadvantages to each?
thank you

durso = silence in my exp. the no sucking or waterfall noise if the tank is already drilled reef ready thats what i would do but after seeing several tank setups with a calfo style i think thats the way to go there.

I dont like the stockman setup cause it looks like you can get more flow outa the dursos

I talked with Louis from Aquatic Warehouse, because I am having this problem with my 240. He suggested I go with the durso incorporated with my calfo to provide the quietness which Chris was refering to.

Those weren't the answers I was hoping for, but thank you very much. I got some parts from savco and their 2" plumbing pieces aren't quite has big as homedepot's. I am going to put it together and see exactly how much room it takes up.
Does any one out there use stockman? In theory I would think you could get more flow from a stockman because it has more smaller holes. The total combined diameter of the small holes has to be greater then the diameter of one big durso. Therefore I would think more flow. Is that not right?

Just remember one thing. Regardless of the size of your durso or stockman your only going to get the flow the bulkhead and pipes leaving can handle. There's a calculator out there somewhere that lets you know what the max you will get through your drain pipes.

One thing I prefer to do with my dursos is use one size larger pipe than the bulkhead, it appears to help keep down any gurgling sound and the occaional flow that goes up and down in the overflow.

One other thing to think about on these is if you have large snails make sure you have some sort of way to keep thm from getting into your drain pipe and causing a flood in your house. I use use plastice wire ties and tie on a small piece of eggcrate to the durso inlet.

Is the stockman like the GurgleBuster? Can you post a link so I can see what the stockman is, I googeld it but came up with a lot of cow stuff...LOL

the easiest way to google anything pertaining to sw is to do as so
stockman saltwater

That's how I found it. Most times you'll get excess garbage, but if you add saltwater to the end, no problem!

A good link on the durso's is www.dursostandpipes.com

ok the point of a stand pipe is to eliminate the crashing sound of the water as it plumits towards the bottom of your tank to drain. so to eliminate that we use the standpipes. becuase of the design of the stockman found here http://www.rl180reef.com/180/pages/standpipe/mods/stockman.htm
you will most likely recieve less flow because of the restrictions unlike the open design of the durso found at captexas's link above. im not sure what you plan on doing down inside of your overflow but im not sure you should be mainly concerned with conserving space.

you or the mfg put a 2" bulkhead in the bottom of that tank for a reason... to get max turnover and drain it at an efficent rate
IF in your case after putting in the durso you dont have enough room to put in the standard return that most people have on their tanks(comming back up inside of the overflow) then get you an ocean motions 2 way and drill an output in each corner of the tank to distribute filtered water and help solve your never ending flow problem that all of us have.

as for your theroy of more holes in the stockman = more flow WRONG the diameter of the pipe is still going to be the same so you wont get more flow ie a baseball stadium lets say has an stairway that is 30' wide and fits 30 ppl /second well we can use an entrace the same size (durso) and get a flow of 30ppl/second. but if we used the stockman style entrance and had a whopping 100 turnstyles and could fit 1 person/second or 100 ppl/second total, they will still be stuck because your stairway or in your case your bulk head can only fit 30 ppl/minute

Nice explanation! Thank you for clearing that up. Obviously, the opinion around here is to go with the durso. I think that is what I will do. I will have to go home, take a look at the everything, and figure out a way to make it work. I might be worrying about something that doesn't matter. I am trying to save a few inches on a six foot long tank.

[Headless_donkey]

If it matters It is going to be a durso. The tank is off getting drilled.

[5.0Stang]

I can't recommend it. But people have claimed to reach rates as high as 800 to 1000 GPH with 1 inch bulkheads rated for 600 GPH.

If your durso is still noisy - and they can be if they drain thru a "T", drill a couple of holes in the top of a cap and put it on. Then put a couple of pieces of small tubing thru the cap and down past the turn. It will help release any trapped air.
