Full Version: What Filter For My Tank
RafflesGold Forums > Discussion Area > Green Water, Filtration and Tank Setup
I am preparing a new tank 3 footer (200L) for my goldfish

i have 9 medium size ranchu

want to know what size of cannister filter can i use, do i need a 2400l/hr filter or less in consideration of the water current.

please feel free to advise.

200L if you fill it to the brim,I think it is only abt 160 to 180L (depending on width).

You are overstocking.Keep a max of 3 in the tank.

If you want to use cannister or OHF,try not to exceed 4 times water turnover per hour to prevent excessive current.So if your capacity is 200L,the pump shd not exceed 800l/hr.However do take into consideration the head loss of the pump which should be available from the manual.There is normally a pump performance graph which shows the effective pumping capacity with ref. to the height that it is pumping.
there are better filter out there suitable for goldfish and are also cheaper options....

OHF, sponge filter etc....
