The only reason lr
rubble is recommended for canister filters instead of the usual media is because excessive waste tends to build up on the sponges/bio-balls that typically come with them and can cause no3
problems if not properly cleaned. Lr
rubble cuts down on that but even that can build up waste, just not as fast.
I have a ton of lr
in my 55 (almost too much) but still use a Magnum 350 with bio-wheel so I can transfer the wheel over to my qt
tank at any time and for added water circulation. IMO lr
alone is fine and a canister filter in addition to lr
is fine also as long as you keep it clean. (I clean mine every two weeks)
I have 2 media containers for mine and keep lr
rubble in one and use the other for ac
, chemi-pure, phosguard & any other chemical filtration I might want to use. I donâ€™t use the filter sleeve personally but even that can be used if you clean it regularly.
