    Actually I ask cos was wondering if i upgrade to 4ft, without chiller, with sump tank and sump pump, what would be the temp.
    compare with my current 3ft setup of total around 30W (wo lights), which i am getting around 27deg.
    that's why was thinking getting a pump to test out the temp diff.

    question: for a 4ft tank, what should be the flow rate of the sump pump?

    Wat is ur current pump brand?

    As much as u can if u plan to keep SPS eventually. Typically, at least 10 x turnover.

    Can't remember wat brand cos threw away box liao.
    bought from sea life, 1000 ltr/hr, my tank volume ard 150 ltr.

    question: my pump for ugf can work both ways. Current setup is used for conventional way.
    Shd i reverse the flow, changing to reverse ugf, would this be better in nitrate control?
    Then install a wave maker to take over the current pump's function? as my pump serves to power the ugf, plus making some waves...

    Hi JC, my 3 ft tank with undergravel filter is VERY high in nitrate.
    was thinking switch off ugf, put in a wavemaker (what you have mentioned some months ago!)
    What's the adverse effect of doing so? Worst case scenario?

    Hi Darylyap, to remove nitrates u need some methods to export it from ur tank. Removing the UGF will only prevent it from rising but do note that feeding also will contribute to ur NO3 build up.

    If u intend to remove ur UGF, make sure u have a decent skimmer and the wavemaker to help ensure that there are no died spot.

    Since ur tank is small, u maybe able to control ur NO3 by doing regular water change (e.g. 50%).

    Cheers

    Having a FR works better than just leaving the media in the sump. It optimise the media better coz the media is suspended in water column and does not remain compact, this means that the absorption of wastes like phosphate are more evenly distributed as compared to just leaving the media in the bag and dump inside the sump
