    Understand that for plant tank, we should use external canister filter as compare to overflow filter as the CO2 which is dissolve in the water will tend to dissappear from the overflow filtering.

    Anybody can comment on this?

    it will depends greatly on the fall/drop of the water and the disturbance of the surface

    Exclamation

    One other concern is that does the smaller fish gets suck into the overflow filter outlet, as it is normally quite a big gap as compare to the canister filter?

    Somehow, I think with overflow filter, I think the water temperature will tends to be lower as compare to canister filter, it's like the Teh Tarik effects which one use to pour the water from 1 cup to another to cool down the drink.

    But in the case of the canister filter, the casing is enclose, therefore water temperature will tends to be higher.

    Can anybody verify this?

    Cheers

    Last time I went to Y932, the boss also says his temp is lower because of the overflow effect.

    agreed with cooler temp with overflow effect but the con is the loss of co2. Not much planted want to use overflow bcos of this. At least for me. I rather used the fan to cool the tank instead.

    OK... My tank is 6 ft by 2.5 ft by 2.5 ft but actual water height is 2 ft (After tanking off top and substrate height)

    Sump is 3 by 2 by 1.8 ft. I use a Dymax 3000 pump but it goes through a few 90 degree bends (PVC Piping) and also a one way valve (Allows water only one direction) The water pressure back into the tank is thus slow... thinking of changing to a bigger pump....

    From my understanding... many people use sumps for bigger planted tanks in the States...

    Its difficult to explain but if you wanna drop by can show you the set up I have... I am living at Telok Blangah Heights....

    I started to investigate the sump system (Overflow) and its more natural way water filtering. The benefits are many folds.

    Personally, I think Planted tank not really require a sump system because the filtering as not all that important as compared to people who keep gold fishes, Koi , arowana or Pleco for example. For planted tank, the bio-load is low and a simple Eheim External Canister filter is enough.....Even the output can't be too high as it will dissolve the CO2.

    In my next tank, which likely to be a 5ft intended for Pleco tank, I'm planning to use the internal sump system. The sump is open system and can see anything in the medias whether dirty or not. And changing of media is very simple.

    Thanks for the open house I will pop by one day... its near my office.

    Why i ask because from the dark side where I came from turnover is important due to the oxygen requiremnet. Guess planted tank is different ya... and your pump, after the head loss for such a big tank, i can imagine how little water movement you have.... my 3ft tank already uses a 2500l/h return pump last time... anyhow, thanks for the info. I will let you know when I have free time to go by
