Possibly among the few that are on the market
I loved it mainly because it is almost among
the only few internal filters in the global
market which support both a huge sponge
attached and a big box which can carry a
pretty large size of cylinder ceramic media
for the culture of beneficial bacteria which
cycles the aquarium water.
Also it looks very reliable with high quality
materials and has a durable construction .
It is also qiet when in comes in small flow
rates.
The only drawback is that it gets partially
clogged if I try to put a resin for absorbing
nitrates or dissolved organics that
accumulate in the water. Other than that
it is great for holding the ceramic cylinder
media.
