Andrew, if you don�t like what people says in this list maybe you should
change to a cibersex chat or something like that.
I think Shane is right in many points, and if I don�t agree with her I just
don�t do what she says, instead of insulting her.
This is a friendly list, avoid those manners please.
Marco

Subject: RE: silica sand ?
Andrew,
Maybe you could chill out a bit with the sarcasm. Is there a problem with a
discussion to the upsides and downsides to keeping both types of systems? Is
it just that you and someone with Dr. in front of their name know the one
and only way to set up an aquarium? Do you really think it is okay to give
partial information to aquarists and let them figure out the rest for
themselves? Why is it that you insist on letting everyone know how outdated
they are and if they arent keeping a system a certain way, your way, that
they dont know jack?
Maybe you didnt see the three or four times I have written that sandbeds can
be an effective way to set up a tank? Or is it that I just didnt agree with
you 100% that you dont like? Do you really feel like a DSB with a refugium
is the only way to set up a successful reef aquarium?
On a final note, I dont advocate packing the tank full of LR, using a large
UV or using crushed coral. I dont use either, although I do know many people
who have quite successfully. Maybe you should go back through the emails
and read the discussion.....oh never mind.
