Can I see pics of your dual overflow plumbing/pipe routing?

    I am working on my return plumbing on my 180 and I am getting some noise and bubbles etc..
    Was wondering how everyone was getting the pipes in the water, elbows etc..
    The cap on the durso have been drilled to 1.25" to eliminate the surging/flushing
    Here are the durso pipes I made
    [​IMG]
    ok, here is the right hand side plumbing..
    I am getting waterfal noise from right here
    [​IMG]
    then it goes down a bit and tees off
    [​IMG]
    I have it going down to the fuge and its still puts out some bubbles even with the pipes so high lol. yes I have a vent in the cap, without the cap it makes alot of noise and splashes everywhere
    notice both valves open, on this side.. if I close one or the other it puts out alot of bubbles
    [​IMG]
    here is where it goes into the water, notice the bubbles.. notice the bubbles.. it makes noise and eventually bubbling is gonna make alot of salt creep everywhere
    [​IMG]
    here is the left side plumbing

    this my first plumbing DIY so I dont know if the bubbling in the sump is normal or the noise lol

    IMO the noise is inherent in plumbing of this type. I have some bubbles come from my drain too. It's really subjective though, I don't mind the noise, others may think it's really loud.

    I can get the bubbles nearly silent, I just think that it will be an issue down the line with the bubbles popping and getting salt creep everywhere.
    I was thinking of switching that drain to a spa flex, but I am not 100% sure that this would cure it. I have no experience with pvc for the drains so I wasnt sure if this was normal noise/bubbling.

    I have similar problems with waterfall noise in my plumbing. I am pretty sure it is the 90 degree elbows like you have, I have the same thing. I think that using flex hose would eliminate alot of it. I might redo mine one day but the noise doesn't really bother me

    The only way to eliminate bubbles entirely is to use the herbie method (or something based on that method) which uses a siphon drain line along with an emergency drain. Otherwise your standpipe is always going to be adding air to the mix on the way down to the sump.
    There are things you can do to slow down/eliminate salt creep, like using bubble towers and filter socks and stuff but it all needs more maintenance/work to get done.

    Your issue can be easily solved by making a simple gurgle buster. I will have to take pics of mine because this is the third time recently that a gurgle buster made of PVC will alleviate the sounds ad spray.

    The issues are not from you tank mounted overflow, but rather how the water enters the sump.

    Here's mine.

    [​IMG]

    It is simply a tee, with a street El, and a length of pipe with a cap with a hole in the top.
    There is no need to glue these as friction fit will hold them in place. Also, you may need to adjust the angle of the gurgle pipe. Mine needs to be pretty much staright up or it will gurgle.

    it works pretty good, for gurgle and noise eradication, but it does nothing for microbubbles. I am engineering a 2" pvc gurgle buster to trap the bubbles as well, but have yet to finish it.

    The hofer gurgle buster does work well, but it will still allow gurgles and bubbles from the water entering the sump.

    Do both and you should have a silent system. FWIW, my durso standpipe is actually pretty quiet.

    I know this is 5 months old, but I'm very interested in this method you mentioned to silent the Overflow, and specially, the part where you mentioned the reduction of the bubbles going in the sump. My overflow box is pretty silent, with some occasional gurgling sound... not too frequent to annoy me, but believe me, it's the air bubbles going in the sump (at faster flow rate) that annoys me with the noise and it creates lots of salt creep I would like to eradicate both if possible or drastically reduce.

    I know about the Herbie method, but it only works with Reef Ready Tank (ie. pre-drilled tanks) and mine isn't, so a hang on back overflow box was a necessity for me. Is there anything I can do to reduce the bubbles other than reducing the flow on my drain which I know it's bad, but I have a pre-filter and snails can't get in the drain. In fact, I have two Dwarf Ceriths living in my overflow box (they were trapped in there before I put finer mesh on the intake) that won't/can't get to the drain pipe... I kind of like it, it keeps my WEIR box clean of algae.

    Thanks for any help.

    - Magnus.

    Really it is only a pipe, with kind ogf a reverse durso on it.

    I have since changed toa massively oversized 2" version and it made it even beter.

    I drilled a bunch of holes int he bottom area of the 2" pvc toward the bottom.

    It seems to work pretty well, but I drilled holes too high into the gurgle buster to keep the bubbles in the pipe.

    While the durso overflows do work, and are much quieter than many other options, the herbie standpipe seems to be the ticket to making the overflow silent.

    I have not yet tried to make a herbie (or 2), but I suspect I will soon.

    Did it reduced your sump bubbles?
    If I had a pre-drilled tank, I would go with the Herbie design in a heart bit. That would also increase my turn over flow at least to 20 X per hour or so. I have to slow down my return pump to probably 20% or less of its total capacity, and of course, my flow in the DT is great because of the power heads, but as far as turn over goes.... not so good at all. I need to be able to open my overflow box fully, or figure something else out without all the sump bubbles and salt creep.

    I think I've seen somebody improvised a Herbie with an overflow box and some PVC, I can't seem to find it again :(

    I thought the same thing too. It was pretty slick. I think it was on RC. I'll try to find it for you.

    Darn it, it is not where I thought it was. Out of ideas except google.

    I'm so used to hearing my tank that it's eerily quiet when I turn the pumps all off... I wouldn't have it any other way...
