250 litres of water suitable for a submersible pump with a filter
The filter flow required for rearing large fish or adapted to a torrent environment is 5-10 times as much as the tank's water capacity.
its power consumption is the same; in raising ornamental fish aquarium in (not as long as the bottom cylinder, the lift of basic filter) can be ignored, so the filter configuration of the filter pump flow can be considered as long as.
These are usually configured filtering rules, in addition, in theory, power flow and filtration pump pump head of said filter, the greater the power of the filter pump flow is bigger,
(your fish tank 250*5=1200-2500L/H can be equipped with a 1200-2500 litre / hour flow filter pump or filter bucket)
