    Advice needed, how powerful do you set the filter and I guess a good way to gauge is whether there are any water splattering sound, whenever I set it high (with splatter sound) I can see the water flowing in the tank by the small white particles churn up by the wave but whenever I set it low (water trickling out from the rainbar) I can see dead water with debris hanging in midwater and not moving, any suggestion which is better?

    that depend on what fish you are going to keep and if there is co2 or plant. for the latter, you need strong water flows to eleminated dead spot and bring the co2 to all corner of the tank, if your tank is big. but if you are keeping some fishes or shrimps which prefered more of still water, then gentle flow will not stress them

    Set it to the highest that your fauna can handle.

    Are you using a diffusor or a reactor?
    If you are using a diffusor, you need to remove the rainbar and point the point of the out let at the diffusor to encourage the co2 to spread evenly, or you can place the diffusor under the point.
    for a reactor, the you have to turn up the power cos then there will not have any dead spot. and you have to place the rain bar for best co2 spreading.
    but must see how big is your tank. for what i know, shrimps need gentle flow water, it mostly stay on the bottom of the tank. i think you can use a diffusor vis a point outlet. cos only the surface of the water will move and the bottom will have minimum movement.

    If you are worried about a strong outflow, just faced your rainbar inwards towards the glass instead of out.

    Been running at higher power since last night and can see more of the debris either settling or already suck into the filter. I am jus using a CERAMIC ATOMIZER and is it normal to see a stream of co2 even though 1 can see 1-2 bubbles being suck into the tube in the bubble counter?

    This is normal. Since the debris is settled, you should leave it as it is cos you need the water movement for having no dead spot
