Unclenorm,

Please tell me your kidding with "needing" both LR and a DSB... if so that
is just plain garbage! Ajay can have almost whatever setup he chooses
provided he understands how it will function and is willing to deal with
it's pro's and con's.
U.V. isn't evil either, but has it's place, certainly hang on to it. I
agree with the assessment on the "wet/dry" process though unless your
running one with no media. That might make a decent sump out of it. The
canister filter may come in handy for cleaning the tank so don't just hurl
it into the trash bin or something.

Hi Ajay,
LR and DSB isn't an either or, you need both, and 4000
litres per hour is way to low for flow, I said 4000 gall per hour not
litres, in litres it would be 18000 or more. The normal recommendation
for most good reefs is 20 times the volume of the tank per hour. some
people would use a good bit more than that. A low flow will inhibit the
functioning of the live rock, having said that the flow through the
refugium needs to be on the slow side for the DSB to work efficiently.
regards,
unclenorm.
