Hi,

The problem (not that its a really big problem) is that the mechanical filter can collect organic particles in the pad. Over the course of a couple of days, small bacteria will begin to break it down. In the end, you'll have a bit of nitrate. Sort of like a nitrate factory.

Ideally, you want your live rock or sand to do this work. With a DSB, you don't actually see nitrates because it gets processed directly to Nitrogen gas in lower layers of the DSB.

UV : Yah...so if you ever make a trip to J&L or Big Al's (anywhere around Lougheed Mall), just send me a message. I'll buy the unit from you.
