    Hi

    Have a look at this pic, you will see that there is lots of bubbles from my overflow pipe... any suggestions to fix this?

    If the bubbles dont make their way back into the DT i wouldnt worry about it. Some would even say it helps with CO2 exchange

    the problem is that the salt creep is a lot more, and I think its because off the bubbles bursting and splashing...

    Yeah thats a downside for sure

    What you can do is what worked for me, I added a ball valve on the sump inflow pipe so that i can regulate the water flow coming into the sump. Its a much more streamlined flow now with less bubbles. Also you can try a filter sock

    I do have a ball valve, but I need to keep it open fully so that the DT not overfill. How does a filtersock work?

    Well my inlet pipe stops about 20cm above the sump's water level. There i have a filter sock which catches all sorts of debris coming down the overflow. Its also an effective way of dampening noise and bubbles... Just google filter sock ;)

    Most of the LFS's sell them but they easy to DIY also. I made mine from a spent 1.5L juice bottle and some fine mesh material which is filled then with filter floss... The amount of gunk i take out every second day is truly amazing

    So will any mesh material work? Does it need to be above the water or submerged, seeing that my overflow pipe is in the water almost at the bottom

    My pipe was in the water so i cut it off above the water line to install the filter sock, just checking to see if i saved any pics of it somewhere, otherwise PM me your cell and i will mms u a pic later when i get home...

    You get these bags from the LFS, its used to house stuff like carbon, purigen etc in flow pumps. Thats what i use

    wow you lazy...
    click the link, go to bottom of page 1.
    :)


    ok,
    copy and paste - just for you ;)
    A 100mm PVC pipe. With end cap. Opened up with dremel so that downpipe fits snugly into it. Downpipe goes down inside about 150mm. 2 small 4mm holes drilled into end cap to allow the air to escape. Basically the same size as my TS2 skimmer lid breathing holes. At the bottom of the 110mm pipe, it is cut at 45 degrees angle to allow the water to flow out and to prevent itself from sealing the flow against the sump base.
    Actually the end cap was the base part of a soil vent valve. The valve itself I used as the Durso. The base as an end cap.

    PROBLEM SOLVED.

    no more bubbles escaping.
    no more noise
    no more salt creep
    :thumbup:

    like a car exhaust. :)

    Water gets diffused in the 110mm pipe. Less flow. So that the water cannot pull the bubbles further down. Bubbles get a change to move up.
    The bottom end of the pipe got 2 slats cut at 45degree angle. So the pipe ends on the sump floor, but cannot close the flow. So water exits normal at the bottom.
    The plus side is that it does stop the bubble noise as well.

    Come around one day. And I can take it apart for you.
