    Hey guys

    I recently built a 600 cube and have just started the cycle process. As this was my first time building a tank i made a slight mistake. i have a corner over flow with a box that is 150cm x 150cm. Now the mistake i made was not putting a pipe in the outlet. So it only has a fitting which is small in height. Now when the water flows out it drops really fast making it very noisy. I do have valves for the inlet and outlet and have played around the adjustments but no luck. Any ideas on what i can do. I really dont want to remove the box and fit a pipe since the tank has rocks and water, and that means i will have to re silicone.

    please advise me if you can.

    Thanks

    Definitely going to need a pic, I can't quite picture what you are saying.

    You say you have a ball valve on the outlet, if you close this gradually until the water level rises in the overflow box then that should stop most of the noise.

    Will upload a pic later or tmrw of that specific area. I tawt abt the floss but i cant get my hands in there since the tank has bracing on the top. So my best bet is to remove the bracing and fit the pipe and then re silicone. But really didnt wana go that way.

    But thanks for the advice.

    Basically it sounds like there is no stand pipe in the overflow, causing the water to fall all the way to the bottom and making the noise. You dont need to silicone a pipe in the fitting. You can just push it in. This will raise the waterlevel in the overflow box and lessen the noise.

    Google durso standpipes. It is what you are looking for.

    If you cant add a standpipe then you will have to add a ballvalve to the outlet and throttle it back so that the waterlevel in the overflow box rises.

    Depending on the fitting you used, you might be able to pvc cement a durso in, which will only require an hour at most to dry

    It's never a good idea to throttle the outlet by the way, you stand the chance of flooding :)

    i think i have a similar issue... i'm thinking about putting some valves in to control the flow rate, i'm just scared that they block up though, I might put in some kind of override though although i still haven't got it completely figured in my head yet. One thing i did do to reduce the "sucking" noise was put a piece if 1/4" hose in one of my overflows. might need to take pics to explain that one....
