I have been considering adding an Iodine supplement to
my 60 gal reef .  I was reading both Thiel and Tullock's
books on supplements and they both suggets using Iodine
if keeping macroalgae.  I don't.  However I use ozone
with my skimmer.  Any experience reef keepers out there
have opinions about adding iodine.  If so is Thiel's
supplement the best?

Please post on Netnews I use someonelse login.

Thanks

I don't use ozone and I'm not sure of any adverse effects when using iodine, 
but I use iodine in my reef.  I've heard it helps calcerous algae.  It seems to
help my soft corals and shrimp, especially during molting.  It also supposedly
helps prevent certain fish diseases.  I'm currently using Kent iodine.  SeaChem
also has a new concentrated iodide that looks promising.  It's an additive 
that I add on occasion but I do use it and I know of others that swear by it.

Hi,

I am thinking about getting an oscar, but I have a few questions first.
The main question is how much do they eat?  I know they eat alot, and
I don't have a problem with that, but  how often should you feed it? 
How do you know when the fish is hungry?  Also, could someone give me
a rough estimate of how much it will cost a month to feed the fish?
I have the money for a tank, etc, but I don't want to get the fish and 
end up starving it to death, due to lack of funds/poor planning.
 
Thanks in advance.

SMiles!

Just sos you know, I have 3 100w and 2 250w Visitherm heaters.  In my

It sounds like the sensor or the switch is malfunctioning.

I asked Mr. Pet Store about Nitrate filters during a conversation we

the tank slow flow canisters, sort of like the ones Moe has drawn into
his tank set up diagrams in his handbook.  Instead, he mentioned the
Nitrex stuff and the proper use of it in a Nitrex Box.  He said that
one of his other customers already had reported success in reducing
nitrates with it.

Do any of you have any experience about the effectiveness or harm of
using a Nitrex Box?  I would put it within my UGF, effective choking a
good part of it off (by eliminating the flow through the gravel that
covers the box).

Subject:    DIY skimmer- help on design

I'd like to get some feedback from those of you that have built
(and designed) your own skimmers. I've looked at the DIY plans
(not sure I understand it all), and I've looked at other people's
designs also. Big questions- is there a formula for computing
waterflow (volume) by airflow (volume) over that waterflow to
see what size is good for an aquarium? I want overkill, and am
designing a 3-4 ft tall skimmer (3-4 inch diameter) for a 55 gal.
would a 2 foot tall still be overkill? is 4 inches too wide?

My design question- most of the skimmers I've seen have the
water flowing into the chamber at an angle, causing a circular
motion of the water in the tube. One person I know who has built
a lot of skimmers now builds his water intake pointing straight
down- he claims that the extra agitation of the water in other
designs causes more of the protien and organics to be knocked
loose and is less efficient. Any comments?

I just had a 48 incher do the same thing.  If you look at the add for these bulbs
it sez something like "shuts down when usefull life is over".  I've never been
very comfortable with that.  Sounds like whatever technique they are using 
could cause pre-mature death.  And besides, I use "old" aquaria bubls around
the house for us humans so I get annoyed when the bulb "decides" that it's

What kinds of problems?  Not even two-pass assemblers will allow or fully
handle forward references on equate's or org's (because they can lead to
inconsistent circular references).

On the other hand, even a one-pass assembler will be able to handle forward
references in bytes in the generated memory image, since all this requires is
deferring evaluation of some expressions to the end of the first pass and then
backpatching holes in the object file.  Then all the linker has to handle are
holes involving external references, just like with any 2-pass assembler.

 Think about using one of the more self-contained microcontrollers
 (Motorola 6811, Intel 8031, etc).

 There are shareware compilers available, for the 6809, etc.  Your
 local BBS likely has some of them.  But, a real problem in cross
 developement is i/o, unless you gave an [in-circuit] emulator.  I
 found myself using the 8031/8051 because single board computers
 are cheap and plentiful, as are development software.  Try to
 find an issue of Circuit Cellar Ink, or Computer Craft magazine;
 they have lots of informative ads.

 If you have an MS-DOS 80x86 PC: There'd be a distinct advtange in
 developing your device around the 8088, from both the software and
 hardware point-of-view.

Neither the 6800 nor the Z80 are all that good at C.  I would consider
also the 6809, which is well-suited for it, or the (gack) 8088.  I
think there is a PD C compiler for the 6809 available out there,
like on the C user's group disks.

The Z-80 is one of the better interrupt-handling processors, at least
so far as handling lots of them quickly.  You need to use assembler
though.

IBM started doing this in their original AT BIOS.  286s were so much faster
than previous CPUs that the commonly available peripheral chips couldn't
respond to back-to-back IOs.  If you want your code to work on the
general case of a "PC compatible", you'd better keep the IODelays.
They probably aren't necessary on IOs to different devices, but it
is pretty hard to be certain which physical devices any given
combination of port addresses may be on in the general case.

Are you certain about this?  My understanding is that ANY branch clears
the execution pipeline and thus results in a CONSIDERABLE delay.

Yes, any branch taken does clear the pipeline, but on a 486 it only takes
3 clocks until the next instruction starts executing.  3 clocks @ 40MHz
is only 75 ns, not what I'd call a very considerable delay.  The 486 will
not use its write buffers on an OUT instruction (it does on REP OUTS)
so you will see this delay at the CPU local buss, but it may only be 75ns
or so of buss idle time (plus the time for the next OUT to start).
Contrast this with the 386DX where the JMP takes 7+ clocks, and there
will be a memory fetch to start filling the instruction queue, between the
two IOs.
