Tom,
The tank that has no macro, it is the one in the other message that you
described as follows (snip)
"the 90 has about 5-7 inches of LS with a 1 ¼ inch plenum installed. On
this system, I have an Iwaki md 100 RLT running the show from a Custom
Aquatic sump, along with an ETSS DualStack 1200 skimmer powered by a GRI
1500 GPH pump."
What types of animals are in this system? Fish, corals etc? The reason I
ask, is because I am curious if there are any other animals in that system
that may be helping with the export of nutrients. I mean, anything besides
that badass freakin skimmer you got!!
Also, I have also never heard of caluerpa helping with the toxic gasses that
build up in a sandbed. From what I read in shimecks article, the build ups
that happen in a sandbed in a tank could never reach toxic levels and that
this is a false rumor. I don't know about that....
Shane C.
PS. Busy day for you on the list huh????

Shane, while your reasons (export of nutrients) for using Caulerpa
are tried
and true, not ALL of my refugiums have Caulerpa in them....Some just
have
hundreds of peppermint shrimp and (can you believe it ?) MORE Live
Sand.
Don't forget, I'm talking about LIVE sand here, not just crushed
coral or
dead substrate, this may or may not make a difference with nutrient
export.
Also, while Caulerpa DOES take out organics and heavy metals, along
with
nitrate, I've never seen anything that says Caulerpa helps remove
toxic
quantities of Hydrogen Sulfide (?) or any other noxious gasses
created by
excessively deep sand, and this is why I told that other dude that I
doubt a
deep sand bed killed his reef.
I have definite necrotic areas in my sand beds that can be seen thru
the
glass (black and gray areas that smell like rotten eggs) and they
have been
there a long while....
Like I said, this whole discusssion started because (someone told
?) that
guy the sand bed killed his tank..Did it entirely consist of
Dolomite, or
maybe BEACH-Collected sand, who knows . Even with the (1000 lbs ? )
of live
sand I use, phospate, silicate, and nitrate remain very low,
including the
system with no Macro.
I don't even change that much water in these systems. I really
believe that
if you start with great water, you'll keep the great water.
Tom
