Good price, but I could only find one review of it. He gave it 5* at Amazon, but in reading his review, it seemed like he had issues getting it going (YMMV).
As for the UV
built into the filter? In my research if the water moves too fast past the UV
bulb, it does little to no good. I got a standalone UV
so it can control the flow, which is no where near 370 gph
and it seems to be doing the job.
