Here's the final piece!!!

I see my frags there......there.....and over there.......ooh yea and that one right there too!
Looks great, I'll be by to check it out in person. PM me when its convenient.

Merv it looks amazing did you figure out what your doing with the 55

Sweeeeet!

Hey Merv, is this how you currently have your setup (out of your gallery)?

I'm using a similar design except that I have a longer horizontal run that goes through the wall to my sump room (you can check my gallery). Anyway, I am having a tough time with my durso's, but from what I have seen you do in this thread, my design is not all that different.

I see you have a ball vavle...do you use it at all?

You use the 3/4" as emergency only? All water exits through the 1" drain? What happens as the water exits the 1" drain and meets up at the "T" junction...does it 'back-up' into the 3/4" durso?

Mine is kinda Pi$$in' me off and I'm thinkin of disconnecting the two so they drain independently. I think that with the Megaflow mod, the 1" drain should be able to handle the flow of my MAK4.

Thanks...

Nice Pics :eek1:

I see you have a ball vavle...do you use it at all?

Yes, that is my current setup. The Ball valve is simply used to regulate how much water flow I need in the refugium, which I haven't really started yet. I'm gonna give the Tank a week or two to start producing some kinda waste, as I added 30-35 gallons of fresh seawater during the move, so any kind of waste had to have been diluted.

You use the 3/4" as emergency only? All water exits through the 1" drain? What happens as the water exits the 1" drain and meets up at the "T" junction...does it 'back-up' into the 3/4" durso?

Actually, the 3/4 did end up having water coming down of it, but not at "full force" if you know what I mean. Majority of the flow is taken care of the original Durso. The T junction does not seem to have any problems with water backing up, I also used 1 1/2 inch pipe so that there is less pressure. What size durso did you make? Mine is made out of 1" pipe then reduced to 3/4 to fit in the smaller bulkhead. Don't forget to use airline tubing up top as well. They will completely cut out any gurgling (I used 3/8 silicone pipe from HD, about 24 inches long)

1" Drain: Durso is 1.25" reduced to fit the 1" drain, then back to 1.25".

3/4" Drain: Durso is 1" reduced to fit the 3/4" drain, then back to 1", "T"-ed into the 1.25" connecting it with the 1" (now 1.25") below the tank.

Rest is 1.25" to the sump.

The "top" of my two durso's are exactly as yours (I believe) except I can't remember if they are 1/4" or 3/8". I have "airline" tubing connecting...if I close them off completely, the level on the overflow DROPS and all I get is sucking...If I leave them both open all the way, then level is fine (sort of) except it fluctuates up and down about 1" with no sucking, but still loud.

Whats that sound like to you? Not enough air getting in? Some ideas and advice would be nice!

 

[concept3]

definitely not enough air. what size air line tubing did you use? I'm using either 1/2 or 3/8 I think. I'll check when I get home later tonite.

 

[RichT]

I'll check when I get home later tonite.

hmmmmm......lets examine this......not at home.....on the computer during the day. Quit goofing off and get to work !!!!!! Wait a minute, I'm doing the same thing. Ssshhhhhhhhh:bum:

That would be I.D.

definitely not enough air.

What gives it away...is it the fluctuating level?

Rich, behave...... or No frags for you!!!



I'm the boss at the store here, remember?

 

[concept3]

That would be I.D.




What gives it away...is it the fluctuating level?

Yes, I.D. on the tubing.

and yes, it shouldn't fluctuate all that much, just minor with no gurgles, you may have a lot more flow that the durso can compensate with air.

Looks fantastic Merv, I'm envious

...you may have a lot more flow that the durso can compensate with air.

Do you mean that I may have too much water flowing through the durso's in general? Or.....that the flow that I currently have is simply too great for the amount of air that I am able to supply...restricted by the size of the airline tubing?

Do you think changing the air intake opening (I mean the whole air-line tube adaptor) at the top of my durso to a larger size will help?

Any ideas on what I might try first...then next...before I start thinking of ripping in down and starting over?


Thanks for the tips.

Yes, not enough air. The durso that originally came with my AGA RR had a conical shaped air intake. I sawed off a little off the top to make it larger and jammed the larger tubing on it. My second durso sports a 3/8 barbed fitting on it jammed with the same hose.

You need more air to compensate for the water flow, basically, your durso's gurgle because the water level fluctuates up and down, which means there is lack of air compensation.

Try this: If you have a long enough airline hose, you should be able to blow air in it without too much exertion as the water goes down. You'll hear that it's quieter as well. Or you can try hooking up a spare air pump on it if you don't want to blow in the hose

It got very frustrating in the beginning since I couldn't figure it out, but now I know the specifics, it's awesome how much a little bit more of finagling helps.....

If it keeps on gurgling some more, raise or lower the second durso until it stops. That took me like 4 days to figure out as well, it should take you 20 minutes.

Have fun!

Thanks Francis.... how're the frags doing?

 

[concept3]

Uhhhh Tony, the Inside Diameter is actually 1/4"......he he he, now I see why I have no gurgling noises.....

Closeup

Here's them in full flow.

Now thats interesting!

Last night I changed to 3/8" then 1/2" ....:eek1:

Helped TREMENDOUSLY! :dance:

So much so, that I was able to increase flow from my MAK4 to the display...if you look carefully in my gallery at the sump, you can see I had to valve down the MAK4 and also re-direct some to the sump to keep too much flow from going to the display.

With the medgaflow mod, the water level is just below the very top of the teeth openings and both durso's are completely submerged running full tilt. (btw...I did the megaflow mod EXACTLY like yours...you took such nice pics, I was able to duplicate them almost exactly) Not the flushing noise I heard previously...just the sound of alot of water flowing through the pipes. Keep in mind that I am running through quite a few turns and about 4 feet horizontal.

Anyway, I am pleased with how it sounds now.

What pump you using as return?

 

[concept3]

Awesome!

Awesome!

I'm using the Iwaki20 @ 600 gph only because the Iwaki40 was creating so much water flow in the sump (Im using a 20L due to height and space issues). I might redo the sump using a 38 gallon, then I'll use the iwaki 40. The 40 is also a little louder than the 20, and I need my peace and quiet in my 8' X 8' dining room! Glad the MEGAFLOW MOD and DURSO MOD and TUBING worked out for ya!!!

Another success story.

You Da Man!

Thanks for all the help...So....I thought I'd show you a few PICS of my own :

Yeah...I'm gettin tons of flow (close to 1000 gph) but my baffles seem to do the job sith this setup (36"x12"x18"):

Here are a couple pics of my overflow:

See any similarities to your setup

And finally, just a bunch of rocks, but its the begining...

Gotta tell you, although I'm not in this group, this thread has been very helpful (actually started all with the "Concept Mod" to the Megaflow).

Thanks again :fish1:
