    Hi guys,

    I received my 2nd new sump yesterday - and boy do I have a problem now.
    I need some advice here.

    The whole they drilled on the side of the sump so that I can connect my 1 sump to my second sump is far to hi up and now they want to charge me more to drill another whole and this could weaken the side panel. What this means is that water can't flow up a pipe to the 2nd pump!!!!!

    So I was wondering - could I pump the water from one sump to the next with a powerhead? I take it that the powerhead will have to be the same lph as the one returning water to the tank.

    I can't raise or lower any of the two sumps within my cabinet and don't want the sumps outside the cabinets.

    My second idea was to use this "problem" to help my chiller - I mean, use a pump to pump from my 1st sump, then through my chiller and into the 2nd sump.

    My first sump is where my TS2 protein skimmer is, and the second is now for my DSB, heater and return pump.

    Please see if you can help me here

    Even if you got two pumps rated for the same lph you would never get it right. You would constanly have to tweak the pumps to get them at the same flow. Also then if one fails you have a flood on your hand. Drill another hole it's the easiest. How much do they want to charge you?

    Without a pic its hard.

    But can you not raise the new sump higher then the other sump? The thinking is you pump water from the first sump up to the new one, and the hole they drilled you use as overflow, back down to the old sump?

    can't turn the panel around cause then the whole will be to far down and won't get flow - hmmmm but you got me thinking - the new sump looks square so maybe I can take the panel out and turn it so the whole is to one side maybe???!?!?!?! Can only check that tonight though - work work work:whistling:

    You can just let the water levels in the sump be that high or you could just drill another hole below that one. If the holes are more that 50mm apart it shouldn't be a problem to drill

    Do this, it works like a charm. No need to balance pumps...
    50mm pipe, with thin 6mm micro irrigation pipe stuck into top part.

    And suction pipe goes

    Just put the powerhead with venturi ALSO in the sump. Else if power go, it will syphon the tank, flooding the sump.

    hmmm now there is a plan - if the power goes off then it won't flood due to the venturi not working - if power comes back on does it do it's thing by its self? as in start filling the otherone again?

    If i do decide to turn the panel can one use clear silicon to glue the panel back or must it be a special silicone? what is the difference between the two anyway?

    Just a clarification. The venturi DO NOT suck the water over. It only starts the syphon, by removing the air inside. Both pipes run down to the bottom with slots cut at the bottom to prevent blocking it. And if any bubbles do enter the pipe, highly unlikely, the powerhead will suck that out. The water flow through the black 6mm pipe is very low. If power goes, every thing just stops.
    You can even use your mouth to start the syphon. Just suck untill you taste salt water. Then you can block it off.
