Thanks a lot guys..I read up a bit also and basically understood that
wet/dry needs to go and I need to rely on either Berlin or Jaubert. I guess
that means either LR or DSB based setups. I am adding LR ..have disconnected
the Wet/Dry and UV..also now looking into water circulation of 4k litres an
hour! That seems too much though..

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.

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 Benjamin,
I don't talk garbage I talk from very many years
of experience and I wasn't kidding to have a successful reef in your
tank replicating nature you need both as nature has, if you research
the whys and wherefores of DSB's and what they accomplish maybe you
will agree with me.
Certainly Ajay or anyone else for that matter can
have whatever set-up they choose and it may work after a fashion.
My recommendations are for a pretty much self
sustaining system that will just require the replenishment of some
essential elements now and again when they have been depleted by your
corals etc. Not one that requires regular water changes and multiple
chemicals all the while to try to correct problems
I didn't mention 'trash bin' nor did I call UV
evil, I said it did more harm than good and I stand by that statement.
I do advocate the use of a good protein skimmer,
by good I don't mean expensive, there are plenty of cheap one that work
perfectly well if properly set up.
regards
unclenorm.

Unclenorm,
Your stating that Ajay needs a DSB as a fact but the reality is it only your
opinion. I'm not saying that a DSB can not be beneficial in some
applications, but you seem to be making one mandatory "to have a successful
reef " which is simply not fact and why I called it garbage. I think there
has been enough DSB debunking done at this point in time that I can't even
see how your pushing this stance.
Yes, a DSB can be a relatively "self sustaining system" but it still has
requirements and it *is* a biological nutrient sink that *will* fill up.
It's not a "set it and forget it" solution. It has it's own pro's and
con's. What happens when the sink fills up unclenorm? I'm sure Ajay would
want that information as well.
I know you didn't mention "trash bin", or call UV "evil"... I did! :-) I
did so because that's how I'm hearing what your saying. What you said was
"it did more harm than good" which is yet another *opinion* stated as
*factual*. UV can have it's place, and even be desirable, in a reef tank
and isn't only to be relegated to a fish only setup. Ajay stated that he
wanted to "shift completely to a reef setup". From my view that simply
isn't enough information to start recommending much other than possibly
chucking the wet/dry bio material and getting the canister filter out of the
system.
Oh, and before I forget, your not going to *replicate nature* in an
aquarium, simply isn't going happen. I can't say it's never going to be a
possibility in the future, but it isn't any time soon. I certainly don't
expect it in my lifetime.
