sterilizers aren't worth the effort in my opinion.
exactly. for small aquaria it's a catch 22;
you need ALL the water to be processed, but it has to be done at a flow rate much, much lower than proper filtration calls for.
So you essentially need two filter systems, one for filtering the water in general and another to filter the water prior to going through the UV
Overall not worth it beyond using on a hospital tank.
and the first time you break the quartz sleeve and have to replace it, you'll probably just stick it in the closet.
