compact fluidized-bed biological canister filter, suitable for all types of
aquariums up to 1000 liters. The resealable canister design includes an integral
flow regulator to optimize the fluidization and a non-return valve to prevent
back- siphoning of the media in the event of a power failure. The unit can be
completely disassembled enabling easy access for set-up and maintenance.
options: Hang-on or freestanding external
filter, in aquarium, filter compartment or sump.
Merlin requires a pump rated at 150 gal/hr, 5ft. head pump (not
supplied with the unit).
Capacity - over 20 times the filtering capacity of the same volume
Efficiency - optimum availability of
oxygen, ammonia and nitrite to the nitrifying bacteria maximizes the total
conversion from ammonia to nitrate.
Response - at least 35% faster than a
trickle filter with 5 times the volume of filter media in total conversion of
ammonia to nitrate.
Constant motion-ensures a thin
bio-film (bacteria colony) and prevents build up of detritus that can cause
clogging (channeling effect) and anaerobic areas.
